COVID & Doctor Suicide: Converging Epidemics

Doctor suicide is a painful reality that hospitals, clinic networks, and medical schools go out of their way to deny.

But with the emergence of a documentary called Do No Harm, and a surge of media attention following the suicide of Dr. Lorna Breen during New York City’s first COVID peak, healthcare leaders are finally being forced to reckon with the ugly truth that in many institutions, medicine has become culture of abuse.

American physicians kill themselves at an alarmingly high rate. A least one doctor commits suicide every day in the US, according to research presented two years ago at the American Psychiatric Association’s annual meeting. Investigators at the Harlem Hospital Center in New York conducted a systematic literature review of physician suicides and identified a staggering rate of 28 to 40 per 100,000––more than twice the general population’s suicide rate of 12.3 per 100,000.

The review also showed that doctors have the highest suicide rate among all professions, including jobs in other high-stress fields like the military or law enforcement. 

Those statistics were identified before COVID-19. In 2020, the pandemic is only accelerating existing trends. Stories of medical professionals lost to suicide in the last 5 months are shining new light on long-standing and dangerous shortcomings in our systems of medical education and practice.

A Doctor a Day

The Accreditation Council for Graduate Medical Education (ACGME) estimates that 300 American doctors die by suicide each year. These deaths rarely make the news, are seldom fully investigated, and often go unacknowledged for what they truly are.

Hazards of duty? Part of the deal? Comes with the territory?

Only if that “territory” is the United States.

Medicine is a high-pressure job anywhere. But doctors in other countries are not killing themselves at nearly the rates of their American counterparts. According to a 2019 systematic review by Dutheil and colleagues, US physicians are far more likely to commit suicide than their peers worldwide. Medical suicide rates have been rising in this country over the last decade; in Europe, they’ve actually been decreasing.

Why do so many American doctors and medical students take their own lives? And why aren’t their deaths more widely publicized?

Dr. Pamela Wible, a family physician by training, runs a helpline for physicians and med students contemplating suicide. Her recent book, Human Rights Violations in Medicine confronts the abusive medical culture that underlies physician suicidality

Pamela Wible, MD, a family physician by training, has spent most of the last decade documenting and studying physician suicides.  As a part of that work, she runs a suicide helpline for medical professionals and students. She’s personally documented nearly 1,500 cases since 2012.

Wible believes guilt, bullying, and exhaustion are three leading causes of suicide in medicine. Physicians, med students, and other healthcare personnel are often subjected to abusive, even dangerous, working conditions. Overwork is common; self-care is penalized.

In many hospitals and clinics, the inevitable pressures of medical practice are compounded by conflicting administrative demands, hostile work environments, retaliatory office politics, racial discrimination, and sexual harassment. It all adds up.

“‘Burnout’ is victim-blaming, and deflects attention from the hazardous working conditions that are illegal in any other industry that values safety, and the human rights violations that are rampant in medical education and beyond.”

—Pamela Wible, MD

Hazing & “Pimping”

It begins with the rigors of medical education, and extends through insurance-based medicine’s emphasis on volume over quality. Young physicians in training are frequently subjected to sanctioned abuse and public humiliation in lecture halls and hospital wards. They’re also severely sleep-deprived—itself a form of torture.

For some suicidal doctors, the problems began when they entered medical school. Med students are typically high-achievers accustomed to ranking at the top of their classes. Once in med school though, some feel for the first time in their lives that they might not really be smart enough, tough enough, or brave enough to become “good” doctors.

Within medical culture, there’s a pervasive fear of being weak, unintelligent, or incapable. That fear drives people to hide their mistakes and imperfections and shy away from seeking help, even when it’s desperately needed.

Some level of pressure and anxiety is to be expected in a career as demanding as medicine.  But Dr. Wible sees shockingly toxic elements in US medical culture.

Bullying, humiliation, and hazing are tolerated, sometimes even encouraged as acceptable training strategies. Many doctors can tell stories of getting “pimped,”––an aggressive, rapid-fire style of testing students’ clinical knowledge by asking difficult or intentionally unanswerable questions in class, in the clinic, and even in front of patients.

All that takes its toll.

A 2016 study of med students by the National Institutes of Health and the US Department of State found that, “overall prevalence of depression or depressive symptoms among medical students was 27.2%, and the overall prevalence of suicidal ideation was 11.1%.” Among those who screened positive for depression, only 16% sought treatment (Rotenstein, L et al. JAMA. 2016; 316(21): 2214‐2236).

“There seems to be more mental health distress among first and third-year med students, and definitely for unmatched graduates. In some residency programs, 75% of residents meet criteria for major depression,” Wible says.

Med students experiencing depression, anxiety, or suicidal thoughts avoid seeking care because they worry they’ll be “outed,” stigmatized, and punished if they do.

The stress and pressure––and subsequent mental health risks––only increase once they transition into actual clinical practice. 

They enter an extremely hierarchical system in which they’re often forced to “earn their keep” by filling the most undesirable shifts. Long hours without breaks; weekend and holiday shifts with little time off; isolation from friends, family, and crucial social support—these are not exceptions, but rather the rule for many young doctors.

Sleep Starvation

Sleep deprivation is also a big factor, says Wible. 

Going without sleep for extended periods is comparable to alcohol intoxication. Exhaustion erodes cognitive and motor skills, slows reaction times, and compromises task performance. Doctors who are sleep-deprived are also at heightened risk for motor vehicle collisions and hospital-related injuries.

It is not hard to find a physician who can tell tales of falling asleep, or witnessing colleagues drop unconscious to the hospital floor, while making rounds, treating patients, or conducting surgeries. Perhaps you’ve been one of them.

In other high-stress professions–pilots, air traffic controllers, even truck drivers, for example–there are regulations and work-hour restrictions that limit shift lengths, because everyone recognizes that sleep deprivation and overwork impair performance.

Yet our medical system drives doctors—who routinely deal with matters of life and death that hinge on clear, quick judgment—to the point of exhaustion.

Current ACGME requirements permit interns’ duty shifts to run for 24 consecutive hours––up from a previous cap of 16 hours––and 80 total hours per week. 

Not only do we permit sleep-starved doctors to administer potentially dangerous drugs, monitor patients on a complex array of equipment, and perform surgeries that require great skill––we expect them to do it all flawlessly––and to be nice about it.

In other high-stress professions…there are regulations and work-hour restrictions, because everyone recognizes that sleep deprivation and overwork impair performance. Yet our medical system drives doctors—who routinely deal with matters of life and death that hinge on clear, quick judgment—to the point of exhaustion.

Exhausted doctors are more likely than well-rested ones to make medical errors, which sometimes kill patients. A 2018 Mayo Clinic study found that physicians who made errors were more likely to exhibit symptoms of fatigue, burnout, and recent suicidal ideation (Tawfik, D et al. Mayo Clin Proc. 2018; 93(11): 1571-1580).  

When Epidemics Collide

COVID-19 presented new and unusual stressors for clinicians in viral epicenters like New York City, Washington, DC, and Chicago, where prevalence was highest during the early months of the pandemic.

Emergency medicine physicians and nurses are particularly vulnerable. In centers with very high caseloads they’re working under constant duress, sometimes without adequate protective equipment, in hospitals that were understaffed even before the pandemic. As they treat their patients, they worry about their own risk, and the potential for carrying the virus home to their families.

Dr. Wible, who has provided counselling for suicidal clinicians for nearly a decade, says that since the coronavirus, she’s seen a dramatic increase in the number of calls.

“Volume doubled, and I led group support calls on Zoom to handle the uptick in requests for support,” she reported.

On April 26, Dr. Lorna Breen, a well-respected ER doctor at New York Presbyterian’s Allen Hospital in New York City died of “self-inflicted injuries” at age 49. Her story got the media’s attention, as it represented the convergence of two epidemics: COVID and doctor suicide.

Lorna Breen, MD, an ER physician who committed suicide at the height of New York’s COVID spike, was an accomplished orchestral cellist

Prior to her death, Dr. Breen had treated many coronavirus patients, and she herself had recently recovered from the virus.

“Make sure she’s praised as a hero, because she was,” Breen’s father, also a doctor, told the New York Times. “She’s a casualty just as much as anyone else who has died.” The elder Dr. Breen also stressed that his daughter, “did not have a history of mental illness.”

In its official public statement, New York Presbyterian used similarly valiant language. “Dr. Breen is a hero who brought the highest ideals of medicine to the challenging front lines of the emergency department.”

But an email to hospital staffers did not immediately identify the cause of Breen’s death, reflecting an attitude of denial and obfuscation that Wible says is the rule, not the exception, among hospital administrators.

Breen’s family and hospital “had to use ‘healthcare hero’ propaganda on her immediately, so that she wasn’t forgotten or thrown to the wind as weak,” Wible told Holistic Primary Care.

“They gave her the hero spin because she was in New York City and had a high position in her hospital. Her family made it clear that she never had any preexisting medical conditions and instead suggested her death was due to the coronavirus, to distance her and the family from the topic of mental health issues.”

This denial contradicts evidence Wible has gathered from the nearly 1,500 cases she has recorded. She finds that ER doctors rank among the top three medical specialists most likely to die by suicide. Psychiatrists, surgeons, and anesthesiologists also have a higher risk than others.

Secondary Trauma

Wible believes secondary trauma plays a big role, at least for the latter two specialties.

Breen’s family insists that she never suffered from prior mental health challenges, but Wible says it’s hard to imagine that a doctor who spent her entire career in the ER never suffered a single blow to her emotional or cognitive wellbeing.

“I believe all emergency medicine doctors have mental health wounds,” Wible said.

It is common to hear clinicians say that experiencing or witnessing a catastrophic injury or illness early in life is what inspired them to pursue medical careers. Wible finds that “many EM doctors have experienced significant trauma in their childhoods––then they go into emergency medicine and are re-traumatized every day.”

Even those who did not experience childhood trauma will invariably incur “occupationally-induced mental health wounds” while working in the emergency department. “If they have not sought appropriate care, then they are still wandering around with those wounds every day,” she said. 

It’s Not “Burnout,” It’s Abuse

“This is tough work, even on the best day,” Wible says of the medical life. “Even in the parts of medicine that seem like they could be happy, there is unforeseen, extreme tragedy.”

In our current systems, the inevitable stresses and pressures of caring for sick, injured, and sometimes dying people, are amplified by factors unrelated to patient care.

Micromanagement by senior doctors or hospital administrators; incessant demands for documentation; veiled threat of punishment or legal consequences for errors; poorly managed and understaffed clinics; incessant time pressures. All these factors leave many physicians feeling not only emotionally exhausted, but cynical towards the profession they once loved.

We call it “burnout.” But Dr. Wible warns that this term obscures the abusive nature of our medical system itself.

“‘Burnout’ is victim-blaming, and deflects attention from the hazardous working conditions that are illegal in any other industry that values safety, and the human rights violations that are rampant in medical education and beyond.” 

Hospitals treat physicians in ways that “break the UN Declaration of Human Rights,” she suggested. Other medical professionals also experience extreme pressure, overwork, and abuse. But statistically, the suicide risk is much higher for physicians.

Hidden in Plain Sight

Part of the problem is physicians’ uncanny ability to hide their suffering not only from colleagues and supervisors, but from family members and friends. Doctors who experience depression, anxiety, or suicidal ideations often view those symptoms as flaws that must never be exposed. Some worry that admitting psychological or emotional distress will call into question their fitness to practice or, worse, might lead to dismissal.

There may also be expectations from family and friends that someone who has “made it” in such a high-status profession must surely be reaping rewards. Some doctors feel a sense of duty not to disappoint parents, spouses, or other loved ones who’ve also invested and sacrificed to make their medical careers possible.

As a result, few people know when a doctor friend or family-member is contemplating suicide.

Dr. Wible—who had her own struggles with anxiety and suicidality earlier in her career—says there are a few red flags: “Excessively happy doctors are often hiding their emotions and pain.” Additional warning signs may include a recent medical liability case, medical board complaints or investigations, and major life events like divorce.

Denial: A Double Assault

Denial by hospital administrators, family members, and colleagues has only compounded the problem of doctor suicide.

“We create the scenario that takes these wonderful young people and puts them in a situation where they can see the only way out is death––and then we bury their suicides,” Wible said. “It’s like a double assault.”

She pointed out that a number of doctor suicides involving ingestion of prescription drugs were misleadingly reported as “accidental” overdoses. It is certainly possible for physicians to unintentionally take too much medication, but this explanation stretches credibility. MDs get extensive training in pharmaceutical use; that makes them some of the least likely people on the planet to unknowingly over-consume a drug.

Doctors do, however, have ready access to controlled substances, which heightens risk of abuse. According to a 2013 study published in the Journal of Addiction Medicine, 69% of doctors reported that they abused prescription drugs “to relieve stress and physical or emotional pain” (Merlo, L et a. J Addict Med. 2013; 7(5): 349-53).

Physicians also possess an intimate and detailed knowledge of human anatomy, increasing the chances that they will complete a suicide if attempted.

Concealing doctor suicides protects medical schools and hospitals from having to address systemic problems. But sweeping the dirty secrets under the rug only puts other health professionals––and their patients––at tremendous risk.

“Suicide is not the problem; censorship is,” Wible argued. “If we would just speak openly about this crisis, it could be easily solved.” 

Effective, evidence-based suicide prevention tools exist––and they can help avert the needless loss of doctors’ lives. “We have the resources to solve this problem. But if we censor it, we can’t make it better. We can’t solve a problem that nobody is acknowledging.”

Get Up, Stand Up

Wible says that to truly shift medical culture in a healthier direction, “we need to normalize the conversation about suicide risk, just like we’ve normalized conversations about blood pressure.”

Education is also vital. Two resources she recommends are the documentary “Do No Harm” by filmmaker, Robyn Symon, and her free audiobook of doctor suicide notes, Physician Suicide Letters—Answered, in which she shares her correspondence with numerous clinicians whom she’s helped to avoid suicide.

The key, she says, is providing a forum for self-expression without fear of rebuke or humiliation. “The system of medical education and practice should be set up in a way where people are able to connect with each other honestly, emotionally and spiritually, without punishment,” Wible said.

Fixing the situation will also require system-wide reforms to create more humane working conditions within medical institutions. Wible believes doctors, nurses, med students, and other health professionals need to stand up and fight for those reforms.

To that end, she recently published Human Rights Violations in Medicine: An A-to-Z Action Guide.

The book documents a spectrum of abusive situations–from food and sleep deprivation to threatening foreign-born doctors and trainees with deportation–that routinely occur in American clinics. It also gives guidelines to help doctors chronicle their own experiences of abuse, and practical action steps for confronting and resolving these situations.

Dr. Wible is certainly not the only physician concerned with doctor suicide, and pushing for change.

Keith Frederick, an osteopath who also served for eight years in Missouri’s House of Representatives, introduced a bill to address mental health in Missouri medical schools after learning that a fourth-year osteopathic student in his community died by suicide just days before graduation.

In the film Do No Harm, Dr. Frederick described suicide as an unacknowledged “occupational hazard” in medical settings. During his years as a legislator (2011-2019), he also sponsored a bill requiring hospitals to examine mental illness and burnout among staff.

Not surprisingly, Frederick’s proposal met initial resistance from Missouri medical institutions. The deans of all six of the state’s med schools co-authored a letter urging legislators not to pass the bill.

Kevin Dietl (2nd from left), with his family. In April 2015, the 26 year old 4th year osteopathic studen took his own life. His parents, John & Michelle, have become leaders in the effort to reform medical education and practice, and to destigmatize mental illness within the culture of medicine.

Ultimately, though, Frederick and his supporters won-out. The “Show-Me Compassionate Medical Education Act” (MO Senate Bill 52) was signed into law in July 2017. It requires medical schools to provide incoming students with information about available depression and suicide prevention resources. It also granted medical institutions the authority to conduct internal research, without penalty, on rates of depression, suicide, and other mental health issues among medical students.

Thank a Doctor, Save a Life

In addition to raising awareness around suicide risk and prevention, expressions of gratitude can literally help keep doctors alive. 

Wible encourages people to “please show appreciation and give thank you cards to your doctors, and ask them how they are doing.”

It might seem simplistic or even silly, but she believes it can be life-saving.

“It can be very hard to reach doctors––they’re often so closed off emotionally. It’s important that they feel validated, normal, and appreciated.” A thank you letter may give a doctor a much-needed dose of positive reinforcement that he or she may not otherwise receive.

Verbal thanks are nice too, but Wible says that penned messages carry an even greater and longer-lasting power. “Thank you notes are huge––especially if they are written. They have a lifespan that goes on for decades––doctors will read and reread them, sit and stare and really soak in the words.” 

Clinics and hospitals might also consider setting up anonymous compliment boxes where staff and patients alike can submit thank you notes to their doctors or colleagues.

She also urges medical practitioners to prioritize their own health and self-care. She herself does this by “spend[ing] a lot of time in nature, hiking, gardening, and with my animals.” She also stressed the importance of strong social connections, like the one she shares with her loving partner.

“And most important,” she added, “I get therapy WEEKLY.”

She holds that all med students and doctors should receive “non-punitive, 100% confidential therapy” every week. Whether it’s for preventive or active treatment, breaking down the barriers around mental health support could help avert the tragic doctor suicides on which our current systems prefer to turn a blind eye.


Remote Patient Monitoring: From Luxury to Necessity

The COVID crisis has catapulted telemedicine and patient remote monitoring onto healthcare’s center stage

Patient self-assessment tools, along with remote consultation technologies, have evolved rapidly over the last decade. Until recently, they’ve been considered luxuries for highly motivated patients and future-forward clinicians.

In the post-COVID world, where many physicians have closed their clinics and patients are deferring all but the most essential in-person visits, telemedicine and remote monitoring are no longer luxuries, they’re necessities. And they will shape the future of clinical practice—especially in preventive medicine.

Here are a few home monitoring and self-assessment strategies that allow patients to take more active roles in their care, while providing practitioners with pertinent information to guide them along the way.  

Befriend Technology

The current situation is obliging all of us in medicine to befriend new technologies. I have found a few basic tracking devices particularly helpful. These gadgets are user-friendly and built for ease-of-use at home. They can accurately track various health measurements and are compatible with many different wireless and internet platforms. They make it easy for patients and their practitioners to view and manage health data together as a team.

Omron blood pressure remote monitoring device

Blood Pressure Monitor: Maintaining a healthy blood pressure is essential. I suggest using a device like the Omron wrist blood pressure monitor. It is lightweight and portable, allowing patients to track their blood pressure on the go. It stores the readings, and the app interfaces with the patients’ computers, so they can keep and share comprehensive records of their recordings. I personally find the wrist version less cumbersome than the arm version.

Digital Stethoscope: Digital stethoscopes such as Eko stethoscopes use Bluetooth to pair with smartphones and tablets through the Eko App. Clinicians can listen to, visualize, and share auscultations of the same quality as if they were listening directly to their patients’ hearts in person, through ordinary stethoscope earpieces. This foregoes the need for close doctor-patient contact. Wireless stethoscope technology makes telemedicine exams much easier.

Assessing Cardiovascular Function

Heart Rate Monitors: The Resting Heart Rate is the number of times the heart beats per minute when someone is at rest. A good time to check this is in the morning after a good night’s sleep. For most of us, the RHR is between 60 and 100 BPM. But this can be affected by factors like stress, anxiety, hormones, medication, and level of physically activity. Athletes and highly active people may have RHRs as low as 40 BPM. When it comes to RHR, lower is definitely better, because it means that the heart muscle is in better condition and doesn’t have to work as hard to maintain a steady beat. Studies show that a higher RHR is linked with lower overall fitness, higher blood pressure, and overweight.

The Peak Heart Rate is 85 to 100 percent of someone’s maximum heart rate. I like to strive for a resting pulse rate of 50 BPM or less while asleep, and not more than 100 BPM when active. 

Most of the current generation of smart phones come with the capacity to monitor both resting and peak heart rates. There are dozens of heart rate monitoring apps that make use of this built-in capacity to provide quick and easy analyses, no math required. I recommend looking for one that suits your patients’ needs. They are very useful.

AliveCor’s Kardia smartphone-based EKG monitoring system

Detecting Atrial Fibrillation (AFib): The irregular heartbeat patterns associated with AFib can lead to blood collecting in the heart, which can form a stroke-causing clots. Tracking Afib at home is pure common sense. Just over two years ago, the FDA approved the AliveCor Heart Monitor— a smartphone app plus a special phone case with a set of sensors. Together they convert the phone into an EKG machine that patients can carry around in their pockets or purses. It allows you and your patient to see a simple version of the heart’s electrical activity in real time on the phone screen.

The system is very easy to use. A patient activates the app, places the index and middle fingers of each hand on the sensor pads, and records an EKG tracing.  In the latest version, called Kardia, the sensors just need to be near–not necessarily on– the phone.

Heart Rate Variability & Autonomic Nervous System Assessment: The effect of heart activity on brain function—and vice versa–has been researched extensively over the past 40 years. Early research mainly examined the effects of heart activity occurring on a very short time scale – over several consecutive heartbeats at maximum. Scientists at the HeartMath Institute have extended this research by looking at how larger-scale patterns of interaction between the heart, the brain, and the nervous system.

Heart rate variability (HRV) is a measure of the beat-to-beat changes in heart rate. The normal variability in heart rate is due to the synergistic action of the two branches of the autonomic nervous system (ANS). The sympathetic nerves accelerate heart rate, while the parasympathetic (vagus) nerves slow it down. The sympathetic and parasympathetic branches of the ANS are continually interacting to maintain cardiovascular activity in its optimal range and to permit appropriate reactions to changing external and internal conditions.

HeartMath’s Emwave system measures heart rate variability, providing a valuable window on autonomic nervous system balance.

With that in mind, analysis of HRV over the course of someone’s day therefore serves as a dynamic window into the balance of the autonomic nervous system. While this seems complicated, it can be tracked fairly easily via a set of user-friendly smartphone-based tools. I recommend looking at Heart Math’s devices & apps that patients can use to monitor their HRV and self-entrain healthier, more coherent, and balanced physiological states.

Remote Lung Assessment

Spirometry & Lung Function Assessment: For patients with asthma, and others in need of frequent and regular spirometric testing, the Aluna Spirometer is the perfect solution. It enables patients to measure their lung function at home, which is a great asset for those who’ve had COVID or who are at high-risk, as it can potentially eliminate clinic visits. 

The Aluna remote spirometry device was designed especially for kids with asthma, but it is also helpful for anyone–young or old–who needs frequent assessment of lung function.

The Aluna system consists of a special breath test device that links wirelessly to a smartphone, and an app for collecting the spirometry data. It calculates FEV1 instantly, and records, stores, and shares the readings. The app also has a medication utilization tracker, and a video game component—particularly well-suited to children and young patients—that explains what the readings mean and allows users to set lung function goals. 

Aluna gives doctors an online dashboard on which to monitor their patients’ spirometry data as it is being collected. Alternatively, patients can choose to share the results over the internet. Aluna can help doctors and patients work together to build a more precise, customized treatment plan that keeps patients engaged in their own self-care.

In addition to these helpful devices and smartphone systems, there are 5 low-tech self-assessments that I recommend that we all use routinely. You can find complete protocols for these simple self-assessments at

Low-Tech Options

First Morning Urine pH: The first morning urine pH is a good indicator of the body’s mineral reserve and its acid/alkaline state. The body routinely uses overnight rest time to excrete excess acids. One’s capacity to do so varies based on toxin load, individual ability to inactivate toxins, and to excrete them. Using a pH test strip, this is a simple, inexpensive at-home test.  Maintaining a pH within 6.5- 7.5 is ideal, indicating that overall cellular pH is appropriately alkaline.  Cells in all tissues of the body function best in an alkaline state. 

Digestive Transit Time: The state of one’s digestive system affects all aspects of health. Measuring digestive transit time gives an idea of how long it takes for food to be digested and for waste to be eliminated. The ideal transit time is between 12-18 hours. Most people who eat the standard American diet have transit times of 36-96 hours, which is detrimental to overall health.

With the help of a few charcoal capsule, patients can easily and painlessly find out how well their digestive organs are doing their jobs. This can help guide decisions about the amount of fiber, probiotics, and other digestive support they need.

C Cleanse: This test uses buffered vitamin C (ascorbate)–the body’s universal antioxidant—to identify a person’s risk of oxidative stress and extent of antioxidant protection.

The process involves taking buffered ascorbate powder in increments of 15 minutes till there is a complete evacuation of the GI tract, or a flush/cleanse is achieved (watery stools). In people who are generally healthy and getting enough vitamin C, this “C cleanse” protocol will give a result of ≤4g. But it is not uncommon to see results of 50, 75 or even 100g, indicating that someone is very deficient in ascorbate. I recommend doing the C cleanse every week.

The skin-pinch test is a simple way for patients to assess their hydration level

Wrist Skin Pinch Test: Drinking enough water each day is crucial for many reasons: to regulate electrolyte balance, support kidney function, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. Being well-hydrated also improves sleep quality, cognition, and mood.

A simple self-test for hydration status that I like to recommend is called the wrist skin test:

– Gently pull up about ½ inch on the skin on the back of the wrist with the hand extended out (not flexed either up or down).

– On releasing the pinch, if the skin immediately flattens, it is a sign of well-hydrated tissues. However, if the skin maintains a little ‘tent’ i.e., stays pinched and then slowly goes back to normal over 5-10 seconds, it is usually a sign of significant dehydration

Urine Specific Gravity (SG): Urine specific gravity is another important measure of hydration and kidney health that can be used to assess the kidney’s ability to concentrate or dilute urine.  Ideally, urine SG measurements will fall between 1.002 and 1.030 if the kidneys are functioning normally. Numbers above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated someone will likely be.

Measuring specific gravity of urine with a refractometer

I like to use a refractometer for this test which projects light into the sample and helps determine the density of the urine.

There’s no question that the COVID pandemic has moved telemedicine and remote monitoring from the margins of healthcare into the mainstream. In many ways, this shift provides new opportunities for patient empowerment and practitioner emancipation.

Office visits will always have a prominent place in medical practice, but they need not be the default setting for everything.

Telemedicine is not the be-all, end-all solution to the problem of healthcare access—many people do not own smartphones or computers—but this technology can help many people improve their health and wellbeing in ways that are convenient and affordable. It open exciting new possibilities for how we practice and experience healthcare—possibilities we are just beginning to explore.


IFM: We Must Expand Access to Functional Medicine in Vulnerable Communities

In medicine, racial and economic differences determine both the quality and the type of health care an individual receives, and this is unacceptable. The disparities in health outcomes between whites and people of color are exceedingly stark. This is true across the field—from conventional medicine to Functional Medicine and beyond. At The Institute for Functional Medicine (IFM), we believe that this must change, and that change must begin now.

Amy R. Mack, CEO, Institute for Functional Medicine

Closing this health care gap begins by examining our core values and mission to ensure the widespread adoption of Functional Medicine. This mission, perhaps once loosely defined, has become clear. It does not mean to ensure the adoption of Functional Medicine for those who can afford it; it does not mean Functional Medicine for the elite or those who have been born with a certain skin color. It is all encompassing. Our mission is to ensure the widespread adoption of Functional Medicine for all.

Why now? One might attribute this clarity to COVID-19 or to the recent unacceptable deaths of George Floyd, George Floyd, Breonna Taylor, Ahmaud Arbery, and others, and certainly, these cataclysmic events have propelled our thinking forward. In health care, the flaws that have been apparent for decades are amplified in this environment, particularly inequities in access to care. The system is irrevocably broken, and in today’s environment, the cracks and the fissures are bigger than ever. Inadequacies are laid bare, and they are undeniable in their form.

And, yet, again we ask truly, why now? The answer: Simply put, because it is long overdue. It is time to be bold and take decisive action to ensure that a zip code, net worth, or skin color is not a determinant of one’s health.

“For certain, those who need Functional Medicine the most are not receiving this care. Many of those who are the most susceptible to COVID-19 are also facing chronic disease; these qualities encapsulate the essential worker—those at the front-line who cannot work from home. Statistics show that minority populations in the US disproportionally make up essential workers.”

COVID-19 has turned the spotlight on public health issues, and in particular, the public health crisis of racism. It did so by highlighting the root causes—the social determinants of health. We know that the disparities seen in health and health care are not the result of personal health and lifestyle choices alone. Much of this stems from implicit biases and unconscious stereotypes that can negatively influence patient-provider communication and result in worse healthcare outcomes for the most vulnerable populations.1

Social determinants of health often start before birth, in the prenatal period of previous generations through epigenetics, and are complicated by a lack of availability of healthy food, a lack of access to equitable health care and a lack of trust in the healthcare system. The medical literature shows that people of color are less likely to receive preventive health services, and that they experience poorer quality medical care than whites.2

Middle-aged Black adults start at a higher level of chronic disease burden and develop multimorbidity at an earlier age, on average, than their white counterparts.3 Despite the fact that minority groups will become the majority nationwide within 30 years,4 13.8% of Blacks report having fair or poor health compared with 8.3% of non-Hispanic whites.5

This issue may be compounded by the fact that the makeup of physicians in the U.S. does not mirror the population. Just over 6 percent of recently graduating physicians are black, perhaps due in no small part to the lack of diversity among academic medical faculty: just 3.6% of faculty at U.S. medical schools are black, while nearly two-thirds are white.6,7

“It is time to be bold and take decisive action to ensure that a zip code, net worth, or skin color is not a determinant of one’s health.”

For certain, those who need Functional Medicine the most are not receiving this care. Many of those who are the most susceptible to COVID-19 are also facing chronic disease; these qualities encapsulate the essential worker—those at the front-line who cannot work from home. Statistics show that minority populations in the US disproportionally make up essential workers.8

According to Sharrelle Barber of Drexel University Dornsife School of Public Health, as reported in an April 2020 edition of the Lancet, the pre-existing racial and health inequalities already present in the US are being exacerbated by the COVID-19 pandemic. These front-line workers typically don’t have the privilege of staying at home.8 Grocery store and restaurant staff, front-line healthcare practitioners, delivery drivers, factory and farm workers, and others are putting themselves and their families at great risk to themselves and their families to protect and bring comfort to others.

In order for this to change, there must be a renewed focus on improving access to quality care across all sectors of the health care system. In the Functional Medicine community, we must agree that in order to truly meet our mission of the widespread adoption of Functional Medicine for all, our evolved primary focus must be on access to care.

To improve access, we need to ask the right questions. We need to learn why many in the population who could benefit the most from a Functional Medicine approach, including essential workers and their families, aren’t aware of or able to access this kind of care.  And we need to identify and act on what we can do to build trust between the Black community and clinicians. We look forward to locking arms with all branches of healthcare in this effort.

To do this critically important work, we will find partnership in clinicians and others from across the field to help inform and implement our decisions and our direction. Driving systems change requires a village of diverse thinkers, innovative disruptors, and risk takers. IFM is fortunate to have many of these types of leaders among us already, but we need so many more, especially leaders of color.

The 2021 E/M Coding Overhaul is Good News: Here’s What You Need to Know

Physicians and practice managers rejoice! For the first time in 30 years, the outpatient

Evaluation and Management codes (E/M) will undergo an historic overhaul by the American Medical Association (AMA) and Centers for Medicare and Medicaid Services (CMS). Many of the changes are for the better.

Any physician or coder who has felt frustrated when trying to tabulate the level of an E/M visit will feel relief at the new guidelines, which take effect January 1, 2021. The new E/M coding overhaul will decrease administrative burdens on doctors and practice managers.

The changes include updated requirements for documenting medical necessity and exams, elimination of “note bloat” by reducing redundancy in copying and pasting case notes, and consideration of the total time a physician spends on a patient.

“While these significant changes will require preparation and training, the overall benefits will be immense. The reduction of complicated coding structures and redundant paperwork will help reduce the hassle-factor, prevent physician burnout, and lead to better overall patient care.”

The Prolonged Visit codes have undergone a transformation as well, though those guidelines have not yet received final approval by CMS.

After extensive surveys of practitioners to determine what changes were needed, the AMA Workforce formed its Guiding Principles as follows:

1. To decrease administrative burden of documentation and coding.

2. To decrease the need for audits.

3. To decrease unnecessary documentation in medical records not needed

for patient care.

4. To ensure that payment for E/M is resource-based and has no direct goal for payment redistribution between specialties.

Times are Changing

Medical Necessity: Under the new guidelines, documentation for medical necessity of a home visit over an office visit will no longer be required. Also, the frustrating prohibition for same-day E/M by physicians of thesame group or specialty has been lifted. These changes will eliminate inconvenience for patients, who will no longer need to space appointments or delay medical care. It will also reduce the number of physiciansgoing unpaid for their exams.

Reduction of Redundant Documentation: No longer will physicians be required to copy and paste irrelevant notes fromprevious visits. This is a very good thing, because the requirements to e-enter outdated information unrelated to a chief complaint (CC)

led to “note bloat” and created a lot of  additional work for auditors and coders. After January 1, 2021, physicians or Qualified Health Providers (QHP) may simply notate “the PHI has been reviewed and verified.”

Simplified Exams: The 1995 and 1997 Guidelines both include extensive Review of Systems (ROS)checklists. These requirements took a considerable amount of time, and were oftenirrelevant. The 2021 Guidelines now require only a medically relevant exam. For example, agynecologist will no longer be required to check eyes and ears.

Choose Your Coding Path: The 1995 and 1997 Guidelines had very complicated point systems for determining the coding levels for History, Physical Exam, and Medical Decision-Making. Time was only a factor if the time spent counseling or coordinating care for a patient was more than 50% of total face-to-face time with the patient or patient representative. Non-face to-face time such as consulting with other practitioners or reviewing charts, labs, and images were not considered at all.

“With the new 2021 Guidelines, physicians may now choose to code based on either the complexity of Medical Decision Making (MDM) or Total Time spent on that particular patient. This is the most significant change, and will truly enhance patient care.”

With the new 2021 Guidelines, physicians may now choose to code based on either the complexity of Medical Decision Making (MDM) or Total Time spent on that particular patient. This is the most significant change, and will truly enhance patient care.

“Total Time” encompasses the following:

• Preparing to see the patient (eg, review of tests)

• Obtaining and/or reviewing separately obtained history

• Performing a medically necessary and appropriate examination and evaluation

• Counseling and educating the patient/family/caregiver

• Ordering medications, tests, or procedures

• Referring and communicating with other health care professionals (when not reported separately)

• Documenting clinical information in the health record

• Independently interpreting results (not reported separately) and communicating results to the patient/family/caregiver

• Care coordination (not reported separately)

Prolonged Visit Codes: Many physicians are unaware of the Prolonged Visit Codes. Under previous guidelines allowed physicians to be paid for extended face-to-face time with the patient. But coding for this involved wrangling with very complicated time-tables

The new guidelines streamline the timetables for the primary E/M codes and prolonged codes. The E/M code levels increase by 10-minute intervals, and the prolonged codes are in increments of 15 minutes. See the improved timetables below.

I have spent thirteen years in medical administration and the last two working as a Corrective Exercise Specialist under both a Naturopathic Doctor and Medical Doctor. I know how onerous coding can be, and I believe these new guidelines will be a big improvement. I applaud the AMA and CMS for their openness and cooperation with practitioners across many different specialties.

While these significant changes will require preparation and training, the overall benefits will be immense. The reduction of complicated coding structures and redundant paperwork will help reduce the hassle-factor, prevent physician burnout, and lead to better overall patient care.

Likewise, the lowered need for audits will decrease administrative and financial burdens on the healthcare system.

Take advantage of the training tools the AMA offers at to prepare yourself and your staff.

Balancing the Vaginal Microbiome: An Unmet Women’s Health Need

Virginia Commonweath University recently launched the Vaginal Microbiome Consortium, a massive cross-disciplinary research initiative (image courtesy Vaginal Microbiome Consortium)

Discussions about the microbiome in human health usually focus on the gut. But what about the microorganisms that reside in other parts of the body––like the vagina? The vaginal microbiome is a critical, yet largely overlooked, aspect of women’s health.

That’s in part because scientists know far more about the microbes in the digestive tract than those in the vagina. Then there are cultural factors like taboos surrounding female genitalia and sexuality that limit open, honest conversations about vaginal symptoms.

Yet some of the most common complaints women bring to their doctors are directly or indirectly related to imbalances in the vaginal flora. Many vaginal symptoms are treatable with natural therapies that rebalance the microbiome and heal symptoms just as effectively, if not more so, than conventional antibiotic or antifungal drugs.

Vaginal Dysbiosis Ups Infection Risk

Though the gastrointestinal microbiome still dominates in research circles, scientific interest in the vaginal microbiome is growing.

Recently, Virginia Commowealth University launched a major research initiative called the Vaginal Microbiome Consortium, to foster cross-disciplinary studies on the vaginal flora and how it influences women’s health, sexuality, fertility, and infant health and well-being.

The vaginal microbiota consists primarily of bacteria, yeast, and fungi. As is the case with the gut microbiome, each individual’s vaginal ecosystem is unique, and influenced by a host of factors: age, diet, environment, hormones, and genetics. The quantity and diversity of microbes in the vagina “have significant implications for a woman’s overall health,” said Liisa Lehtoranta, PhD, manager of research and development in the Global Health & Nutrition Science division at DuPont Nutrition & Biosciences.

Liisa Lehtoranta, PhD, Research & Development Manager, DuPont Nutrition & Health

Lehtoranta, who specializes in research on probiotic bacteria, explained that in healthy women, the vaginal microbiome is usually highly populated by a few species from the Lactobacillus genus. “As a key feature, vaginal lactobacilli produce lactic acid, which creates an acidic [low pH] microenvironment and prevents the overgrowth of potentially harmful bacteria,” she said.

But a host of environmental and lifestyle factors can upset this optimal microbial makeup. Vaginal imbalance or dysbiosis, Lehtoranta said, is a known risk factor for yeast infections and bacterial vaginosis (BV).

“BV is in turn associated with urinary tract infections, increased risk of infertility, fallopian tube inflammation, adverse pregnancy outcomes and preterm birth.”

Vaginal dysbiosis also correlates with sexually transmitted infections like HIV, human papillomaviruses, herpes, chlamydia, and gonorrhea, she added.

Drug-Induced Infections

Vulvovaginal infections account for millions of physician visits annually, ranking among the top conditions for which women in the US seek medical care. Treatment typically involves simple lifestyle modifications plus a course of antibiotics or antifungal drugs.

In the case of a single infection, a standard antibiotic regimen will generally alleviate symptoms. But these powerful pharmaceuticals also disrupt the delicate vaginal microbiome, potentially setting the stage for recurrent future infections that are far harder to clear.

“A classic and unfortunate 3-step sequence of events is often the starting point for people with chronic vaginal infections,” Amy Day, ND, founder and medical director of the Women’s Vitality Center in Berkeley, Calif., told Holistic Primary Care.

Dr. Amy Day, ND, founder and medical director of the Women’s Vitality Center, shares her expertise on supporting a healthy vaginal microbiome

The pattern begins when a patient develops a urinary tract infection (UTI) which is treated with antibiotics.

Hard-hitting antibiotics “throw off the vaginal flora due to killing the good bacteria along with the bad ones that are causing the UTI,” Day explained. They may knock out the UTI, but in doing so, they create the perfect environment for fungal pathogens to grow unchecked.

As in the gut, certain microbes in the vagina are “critical for maintaining the balance of good bacteria to help fend off bad bacteria and yeast,” Day said. It is normal and even healthy for small amounts of unwanted bacteria and yeast to appear, provided there are enough beneficial flora also present to prevent pathogenic microbes from causing harm.

Lactobacilli, for instance, keep infectious yeasts like Candida albicans––the main cause of genital yeast infections––from reaching dangerous levels. Antibiotics or other forces that disrupt or destroy the Lactobacilli, create conditions for Candida overgrowth.

Rebalancing After Antibiotics

It is crucial to rebalance the vaginal flora after a course of antibiotics. Otherwise, the very medications intended to treat one infection might just end up causing another.

“The Battle of Winter and Spring” by Ana Tsittsishvili, a Georgian biologist and artist who “paints” with microbial cultures

Day said that in her practice, it is “very common” to find that patients with long histories of chronic vaginal infection experienced their first symptoms following antibiotic treatment.

“If the pharmaceuticals always worked and didn’t have side effects, I probably wouldn’t see any of these patients because they would just get an insurance-covered prescription and be done with it.”

“That works for some people,” she acknowledged. “Diflucan can knock out a yeast infection and a patient can be fine. But it’s a hard-hitting drug and it doesn’t always work, and it often requires re-treatment and re-treatment if you’re not rebalancing” the vaginal flora.

What makes the UTI-antibiotic-yeast infection sequence even worse is that in many cases, it’s preventable.

Teaching women how to support their own healthy vaginal ecosystems can minimize the likelihood of recurrent infections.

“This is definitely an unmet need in the medical field,” Day suggested. Patients with vaginal infections are frequently, “handed a prescription without finding out first what is truly going on and what needs to be treated.” Others receive antibiotics or antifungals that do not effectively clear their symptoms, which sends them “to the internet to try and research what else they can do for themselves. It’s very frustrating.”

Fortunately, “most doctors are now being more cautious about prescribing antibiotics without first confirming the [presence of a] UTI, so that is a step in the right direction,” Day noted.

The Maternal-Infant Microbiome

Conventional medicine does recognize some additional aspects of the vaginal microbiome, particularly in the context of pregnancy and childbirth.

Take Group B Strep (GBS), a prevalent bacterial vaginal infection with potentially serious consequences for newborns. Physicians routinely screen expectant mothers for GBS in the late stages of pregnancy and provide treatment as needed to prevent mother-to-infant transmission.

But beyond that, there is also the broader idea of a shared “maternal infant microbiome” (Dunn, AB et al. MCN Am J Matern Child Nurs. 2017; 42(6): 318-325). A baby’s gut flora begins developing in utero, but the birthing process will significantly influence the “initial colonization process of the newborn microbiome.”

During vaginal delivery, infants are inoculated with microbes from the mother’s vagina while passing through the birth canal. Exposure to healthy––or unhealthy––vaginal flora can affect a baby’s health even long after birth. Studies indicate that babies delivered by Caesarean section have distinctly different microbiomes than those delivered vaginally. C-section infants frequently carry higher levels of opportunistic pathogens at birth, as compared to vaginally delivered babies (Shao, Y et al. Nature. 2019; 574: 117–121).

Given that a mother’s vaginal flora directly influences an infant’s gut microbiome, some holistic medical practitioners recommend that expectant patients supplement with high-quality probiotics during the last trimester. Supporting healthy intestinal flora after birth is especially important for babies delivered by C-section.

Hormonal Triggers

Bacteria and yeasts thrive in damp, warm environments, so conditions like high humidity or wet clothing can promote pathogen overgrowth. Diets high in refined carbohydrates provide an ideal fuel source for sugar-loving yeasts, increasing the risk of vaginal dysbiosis.

Hormone fluctuations can also trigger infections. Some patients consistently experience monthly flares in chronic BV or candidiasis at specific points in their menstrual cycles.

Right around mid-cycle, “there’s an estrogen spike that happens as part of the ovulation process,” Day pointed out. Recurrence during ovulation is not uncommon in patients who experience frequent yeast infections. For others, infections arise shortly before the bleeding phase when hormone levels start to drop. Still others notice that symptoms return right after their periods, as menstrual blood both adds moisture and feeds vaginal microorganisms.

Low estrogen later in life can be problematic as well. “In the post-menopausal years, some people experience an increase in UTIs and vaginal infections,” Day said. Declining estrogen in the vaginal mucosa correspond with weaker immune responsiveness, likely resulting from decreased circulation. Treatment with local estrogen therapy can help boost immunity and prevent additional infections.

Medical Red Flags

Some women recognize that their symptoms appear at specific times or under specific conditions, but others do not.

You can help by asking patients to carefully track and document when their infections occur. When evaluating a patient’s flare ups, make sure to ask about dietary habits, clothing choices, menstrual timing, and environmental conditions. Do infections occur predictably at a certain stage of the menstrual cycle, or after certain vacations or certain types of meals?

Taking the time to ask those questions may yield vital insights about a patient’s vaginal microbiome.

In cases where the infection triggers aren’t immediately apparent, dig deeper. Chronic infections of the genital tract––or anywhere else for that matter––are medical red flags for underlying problems.

“Yeast overgrowth in the vagina can occur on its own, but I do think about yeast in the gut in cases where the vaginal yeast infection keeps recurring,” Day noted. “The bowel can act as a reservoir, and even after treating a vaginal yeast infection, any remaining yeast can travel from the anus to the vagina and cause another infection.”

For this reason, Dr. Day says she often pairs local vaginal treatment with systemic oral antimicrobials.

Chronic vaginal infections may also signal a compromised immune system. Always “screen for any signs of recurring infections that may indicate an immune deficiency state.”

Test Thoroughly

When treating vaginal symptoms, try to determine the exact cause of a bacterial or yeast infection and treat accordingly. It will mprove the likelihood of successful eradication, and also reduce risk of recurrence.

A sample report from Doctor’s Data’s Vaginosis Profile

Unusual vaginal discharge marked by changes in color, consistency, or smell, as well as redness, swelling, rashes, and itching or irritation of the vagina or vulva, are the typical indicators of vaginal dysbiosis. But “symptoms depend on the infection in question,” Dr. Lehtoranta cautioned.

There are a number of different testing options now available–including home test kits—to characterize the vaginal microbiome and determine what type of infection may be present. One example is the Vaginosis Profile by Doctor’s Data, which patients can complete at home and send to a lab for analysis.

Testing is “a fantastic way to get more information, especially in women who struggle with chronic and recurring infections,” Day says. Results may take several days to return, so testing is somewhat less useful in acute cases requiring immediate treatment. But generally, “it’s so useful to know about [a patient’s] levels of good and bad bacteria and yeast…to help guide treatment decisions.”

Natural Alternatives

A host of natural therapies can effectively treat many symptoms of vaginaly dysbiosis without causing harmful side effects.

Begin by encouraging patients to drink more water.

Supplements like d-mannose, vitamin C, probiotics, or herbs such as uva ursi and berberine are great options for patients with UTIs.

For confirmed yeast infections, Day’s go-to treatment is boric acid or Yeast Arrest, a natural vaginal suppository made by Dr. Tori Hudson’s Vitanica supplement line. The product is a homeopathic suppository with a cocoa butter base and supportive natural ingredients including boric acid, tea tree oil, neem oil, Oregon grape root, Lactobacillus probiotics, and homeopathic botanicals, in a base of cocoa butter. “It is highly effective at relieving uncomfortable symptoms and usually clears the infection completely with twice a day use for 7-14 days,” she reported.

Botanical anti-fungal supplements like CandidaStat (Vitanica) or Biocidin (Biobotanical Research) may further benefit patients by providing additional systemic support during infection treatment.

“If the infection is severe enough that antibiotics truly are needed, then the patient should always be given probiotics along with that prescription,” Day urged. Using “high dose probiotic supplements during the course of antibiotics––taken at a different time of day, two hours away from the antibiotic doses––and then for two to four weeks afterwards, can help to maintain the healthy flora and prevent a vaginal yeast infection.”

She added that vaginal probiotics make good sense “no matter what treatment is used to kill off [an] infection.”

In a recent double-blind placebo-controlled clinical trial involving 40 healthy women in Italy, Profem® was demonstrated to be well tolerated and lead to better probiotic colonization of the vagina in nearly all subjects receiving the probiotic complex compared to those who did not. This leads to an increase in beneficial bacteria in the vagina.

Supplementing with oral probiotics may also help to maintain or increase healthy levels of vaginal lactobacilli. DuPont’s HOWARU® Feminine Health combines Lactobacillus rhamnosus HN001™ and Lactobacillus acidophilus La-14®, two bacterial strains offering “beneficial effects in regards to BV and vulvovaginal candidiasis recovery as an adjunct to antibiotic or antifungal therapy, respectively,” Lehtoranta said.

“Unlike antibiotics and antifungal drugs intended for killing harmful bacteria and yeast, which may be harmful to intrinsic vaginal microbiota as well, probiotic strains in HOWARU® Feminine Health are intended for maintaining the good lactobacilli balance in the vaginal tract,” she said. The probiotics in HOWARU® promote lactic acid and hydrogen peroxide production, which lowers pH levels in the vaginal environment.

Jarrow Formulas’ Fem-Dophilus is another widely used vaginal health probiotic that can be swallowed orally or inserted vaginally once a day at bedtime to help restore beneficial flora and prevent infection recurrence.

The Gut-Vagina Axis

In the same way that diet affects the intestinal microbiome, it also affects microbial diversity in the vagina.

Reducing or eliminating carbohydrates, sugars, and alcohol often alleviates vaginal symptoms and prevents them from recurring. Patients with persistent yeast infections may need to follow a strict zero-sugar anti-candida or low-mold diet. Others with less severe or less frequent infections can tolerate modest amounts of sugar or other carbs.

“There are implications that the Westernized diet and high saturated fat content may cause systemic inflammation, which may have an unfavorable effect on the vaginal microbiota composition through the so-called ‘gut-vagina axis,’” Lehtoranta warned.

Equally important as what’s removed from the diet is what stays in it. In addition to plenty of fresh or lightly cooked vegetables, it is wise for women to incease their intake of fermented vegetables, yogurt, or other Lactobacillus-containing foods.

Patients at risk for vaginal infections can further reduce the likelihood of recurrence by wearing underwear made of cotton or other breathable fabrics, and changing out of tight-fitting swim suits or sweaty workout clothing promptly after use.

It is also a good idea to avoid douching and instead wash the vulvovaginal area with water only.


How Insurers Profit From the Pandemic: A Conversation with Wendell Potter

The COVID pandemic has wrought unprecedented economic strife worldwide. Despite the public hardship, one sector profits handsomely from the pandemic: health insurance.

Healthcare plans are poised to make record profits this year. They continue to collect premiums, but their coverage of COVID care is spotty at best, and with so many clinics closed and non-COVID care deferred, their “medical losses” (aka spending on actual care) are at an all-time low.

Wendell Potter, former head of corporate communications for Cigna, understands the machinations of the insurance industry like few others could. After a long career seeing firsthand how strategic PR and lobbying unfairly tilt the scales toward corporate interests against the needs of practitioners and patients, Potter left the board room to educate people about the realities of the medical-industrial complex.

With his 2010 book, Deadly Spin: An Insurance Company Insider Speaks Out on How Corporate PR Is Killing Health Care & Deceiving Americans,Potter went from being one of the industry’s star spokesmen, to one of its worst nightmares. His second book, Nation On The Take, co-authored with Nick Penniman, reveals how special interest groups now co-opt and control all levels of government.

Potter is now the president of Business Leaders for Health Care Transformation, an advocacy group for meaningful healthcare reform.

Join Holistic Primary Care’s editor, Erik Goldman, for this special live interview with the man TIME magazine called, “the ideal whistleblower.”

We’ll explore:

  • How insurers have taken advantage of COVID to further concentrate wealth and power, while spinning “good guy” tales about themselves
  • How UnitedHealth Group—the largest for-profit insurer, and the nation’s biggest employer of physicians—came to be in charge of billions in federal aid for hospitals on the COVID frontlines.
  • What is likely to happen as the pandemic drags on, and more people lose their jobs–and their coverage
  • What we can do to restore health and sanity to the nation’s healthcare systems

Honeybees May be Allies in Fight Against MRSA

Swedish researchers recently discovered 13 unique lactic acid bacteria in fresh honey and in the honey-producing organs of bees that are strongly active against several virulent human pathogens, including Staphylococcus aureus (MRSA). The findings suggest that honeybees could be valuable allies in the human fight against MRSA.


The investigators, led by Tobias Olofsson, of the Department of Medical Microbiology, Lund University suggest that these unique microbial symbionts found in the bees’ honey stomachs and also in the honey itself could be used as an alternative for antibiotics, with implications not least in developing countries, where fresh honey is easily available, but also in western countries where antibiotic resistance is seriously increasing.

Dr. Olofssons group has been studying honeybee microbiomes for a decade. Theyve discovered roughly 40 lactic acid strains in the honey stomachs of the bees, and have characterized 13 unique Lactobacilli and Bifidobacteria that proliferate in massive amounts and are transferred into the honey itself (108 LAB per gram of honey).

They pitted these probiotic organisms from three different types of honeybees against several drug resistant pathogens cultured from chronically infected human wounds. These included methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, and vancomycin-resistant Enterococcus (VRE). They also tested a number of conventional antibiotic drugs against these same pathogens.

Outperforming Antibiotics

The honeybee microbiota showed marked activity in inhibiting the growth of the pathogens, and in most cases outperformed the antibiotics.

“We can hypothesise that the lactic acid bacteria (LAB) in this case are better than or just as effective as many of the widely used antibiotics in wound treatment today. Combined, the 13 LAB have another advantage over antibiotics: a broad spectrum against a wide variety of pathogens. As we know now, many antibiotics are active only against certain bacteria, for example, metranidazole and anaerobic bacteria,” Dr. Oloffson reported (Olofsson et al. Int Wound J. 2014.)

Of the 13 organisms tested, Lactobacillus mellifer Bin4, inhibited all 14 pathogens tested, and L. kunkeei Fhon2 showed the most potent antibiotic activity. But Dr. Olofsson stressed that it is the combined synergy of the various organisms present in honey that holds the greatest potential for wound-healing and infection control.

The antimicrobial effects of honey or honeybee-derived microbes have not yet been demonstrated in actual human studies, but they have been tested in horses with chronic, infected wounds. Ten horses were treated by topical application of honey enriched with LABs, and the investigators observed rapid resolution of the persistent wounds.

New Chapter, Old Saga

Dr. Olafsson’s work is the latest chapter in a story that is centuries old. Honey has been used around the world as a natural antimicrobial agent for millenia. Its high sugar content but low acidity and water content act as barriers to microbial activity. In numerous studies, researchers have used honey to successfully inhibit the growth of a wide range of bacteria, fungi, protozoa, and viruses (Tan et al. BMC Comp Alt Med. 2009; 9:34).

Previous research has suggested that one of the primary contributors to honeys antimicrobial activity is hydrogen peroxide. When most honey types are diluted, the enzyme glucose oxidase is activated and oxidizes glucose to gluconic acid and hydrogen peroxide (Deb Mandal & Mandal. Asian Pac J Trop Biomed. 2011; 1(2): 154-160).

The Lund University work characterizing the anti-pathogenic activity of lactobacilli within the bees and transferred into the honey adds a new dimension to our understanding of this healthy and delicious food source.

Though promising, it is important to keep in mind that the amount of microbial symbionts and the antibiotic compounds they produce varies very widely in store-bought honey. As with many foods, the fresher and the less-processed the honey, the more likely it is to have potent antimicrobial properties. Highly refined, processed honey will not likely be active.

Profiting from Pandemic: How Insurers Turned COVID into a Goldmine

While many sectors of the economy suffer from the impact of the COVID pandemic, the health insurance industry is poised to make record profits in 2020 (Image by Philip Steury/

For health insurers, the COVID pandemic has been a goldmine. At least so far.

Across the nation, ordinary people and small businesses struggle with both the disease itself and the fiscal consequences of prolonged economic shutdown. Healthcare plans, on the other hand, are poised to make record profits this year.

According to a mid-April NASDAQ report, seven of the biggest for-profit players—UnitedHealth Group, Centene, Cigna, Anthem, Humana, Molina, and Magellan–are expected to turn “positive earning surprises” in 2020. For all of them, stock performances are surpassing previous years’ projections.

UnitedHealth Group (UNH), the nation’s largest employer of medical professionals, saw a nearly 7% revenue rise in Q1 2020, reaching $64.4 billion.  During that three-month period—as COVID spread across the country–UHG’s medical loss ratio decreased by 1% compared with Q1 2019. In laymen’s terms, “medical loss” means money spent on actual medical care.

Bull Run for Some

Like other major insurers, UNH’s stock price remained high throughout the first months of the pandemic. At the close of Q1, UGH was trading at $277.50 per share, up 2.6% from the beginning of the year; it continues to generate earnings and dividends.

According to the company’s Q1 report, “Return on equity of 23.6% continued to reflect the company’s strong overall margin profile. Dividend payments grew 19.1% year-over-year to $1.0 billion and the company repurchased 6.2 million shares for $1.7 billion in first quarter 2020.”

Yes, that’s right. Instead of using its Q1 windfall to reduce premiums for furloughed workers and businesses tottering on the brink of bankruptcy, UnitedHealth bought back its own stock, to ensure that its stock prices remain buoyant.  

It is also noteworthy that UnitedHealth’s president, Sir Andrew Witty, also CEO of UNH’s highly profitable Optum division, took “a leave of absence” this Spring to work with the World Health Organization on COVID-19 vaccine development. Prior to UNH, Witty was CEO of the drug giant, GlaxoSmithKline.  

Aetna, is also having a bull run, despite the pandemic—or perhaps because of it. CVS—which owns Aetna—reported a net income of $2.01 billion in the first quarter.

In his Q1 2020 report, CEO Larry Merlo stated, “Consolidated revenues increased 8.3% year-over-year with growth coming from all segments. Our business performance exceeded our expectations due in part to strong execution and our ability to meet elevated consumer and member needs resulting from COVID-19. We generated $3.3 billion of cash from operations and returned approximately $650 million to shareholders through cash dividends in Q1.”

Merlo’s personal compensation package in 2019 was just shy of $22 million.

Second Wave? No Problem

Not all health insurance companies are booming. But most are doing just fine, prompting Moody’s Investor Services to report in late May that, “Coronavirus-related costs did not “materially impact” seven major health insurance companies’ first quarter 2020 earnings, which increased slightly over last year.”

That’s why Moody’s predicts that the majors will remain profitable even if there is a second wave of COVID.

Several factors play into the insurance industry’s COVID cakewalk:

  • Despite the economic shutdowns, insurers continue to collect premiums from employers, the federal government (for Medicare Advantage and other privatized federal insurance plans), and insured individuals.
  • For most plans, the medical loss –that is, the percentage of premium revenue spent on actual care for beneficiaries—is down significantly since the pandemic. That’s because so many clinics have closed, and so much sub-acute, elective, and ‘non-essential’ care has been deferred.
  • Prolonged quarantines, bans on large gatherings, and travel restrictions mean fewer auto and motorcycle accidents, sports injuries, and episodes of non-COVID infectious diseases. All of this translates into fewer people racking up medical bills that insurers must pay.
  • The actual costs of COVID care are falling most heavily on federal payors, not private sector insurers. That’s because people with severe COVID are disproportionately elderly (Medicare), poor (Medicaid), or uninsured.  

Fed Bears the Brunt

To be sure, insurers face storms on the horizon. More than 40 million Americans have lost their jobs since the pandemic began, and several big employers have declared bankruptcy. That means significant losses in employer-based insurance revenue. It remains to be seen how many companies rebound, and how many of those jobs are restored once “things go back to normal”—if ever they do.

There could also be a massive surge in medical spending once clinics reopen and people who deferred office visits and non-acute care feel safe enough to return.

But even in the face of these threats, the insurers have done much to ensure their future profitability (they are insurers, after all).

For one, many newly unemployed people will likely end up on the federal tab—either in Medicaid or Medicare—or they will scrimp and save to buy private insurance on the open markets. Even if the big plans lose revenue from employer premiums, they’ll likely save even more on reduced medical spending for beneficiaries they no longer have to cover.

Further, a significant chunk of federal healthcare spending will end up going to the for-profit plans anyway, via the Medicare Advantage plans.  

According to Moody’s, COVID-related unemployment “will hurt fully insured commercial risk books of health insurers most, because membership will decline.” But the unemployment “will benefit the Medicaid and individual market [insurer] businesses, which will gain members.”

“HEROES” for Whom?

The insurance industry’s lobbyist sous-chefs have made sure the House of Representatives baked plenty of protections into the $3 trillion HEROES Act currently under Senate review.

Title page of the HEROES Act (HR 6800). The bill, currently under review by the Senate, contains signficant protections for private for-profit insurers

HEROES (Health and Recovery Omnibus Emergency Solutions Act), a proposed follow up to the $2 trillion CARES (Coronavirus Aid, Relief, and Economic Security Act) includes subsidies for continued coverage of furloughed workers, or those using COBRA to extend their insurance while unemployed. It would also provide other funds to support employer-based plans.

In an April 28 letter to Senate and House leaders, a coalition of 32 medical organizations and trade groups—including the US Chamber of Commerce, and several insurance industry advocates—called on lawmakers to ensure that the employer-based coverage system does not collapse.

The coalition states that roughly 180 million Americans depend on job-based insurance—a frequent insurance industry talk-point– and urges Congress to “take immediate action to support employers and workers by protecting and expanding high quality, affordable health care coverage.”

The requested “action” includes:

  • Subsidies to corporate employers that have lost revenue due to the pandemic and are forced to cut employee health benefits
  • Full-cost offsets for COBRA coverage of people who’ve lost their jobs
  • Expansion of “qualified expenses” in Health Savings Accounts, enabling people to use their HSAs to pay their insurance premiums
  • A special enrollment period allowing people to buy insurance in the Health Insurance Marketplaces created by the Affordable Care Act.
  • Subsidies for insurance purchased through the Marketplaces

Of course, it will take heroic efforts to get HEROES through the Republican-controlled Senate. The bill is a Democratic party initiative, and Senate Majority Leader Mitch McConnell has already voiced his opposition.

Whatever the fate of HEROES, it is a safe bet that the insurance plans will remain profitable.

“The one thing these companies know how to do is to make money, to assure their shareholders of a return on investment that Wall Street expects,” says Wendell Potter, a former insurance industry communications director turned whistle-blower.

Wendell Potter, founder Business Leaders for Health Care Transformation

Potter spent 15 years as the Vice President of Corporate Communications for Cigna, before a crisis of conscience obliged him to leave an industry he now sees as rapacious and only out for its own good, usually at the expense of patients and practitioners.

Protecting Profitability

“Insurance companies are really going to have a stellar year this year, because of the pandemic. And one of the reasons for that is because of all the elective procedures that have been cancelled or postponed. They’re not going to happen this calendar year. Some of those will never be rescheduled because unfortunately some of those individuals have died by now, or will die,” Potter said in a recent interview with Holistic Primary Care.

His experience in the corporate board rooms over decades has shown him that insurers are quite capable of weathering social and economic storms.

Deadly Spin, a 2010 book by Wendell Potter

“Since the ACA was passed, insurance companies have made a lot of money. They’ve made record profits even with the restrictions that the ACA brought to the industry. The insurers can no longer refuse to sell coverage to people with preexisting conditions or charge people more because of their health status. But they can still charge older folks more than the younger people. And they’ve really ramped up prior authorization requirements. They’ve shifted more and more people into high deductible plans. They’re increasingly refusing to pay for coverage if you go out of network willingly or unwittingly,” says Potter, author of the 2010 book, Deadly Spin, which chronicles how the insurance industry manipulates public policy to its own advantage.

“So, there are things they put into place that are barriers to care, that protect their profits. Even if revenues drop next year, they will still have these things in place: people will still be in high deductible plans, probably more of them. And they can manage “medical expenses” in a certain way that, I would imagine their profit margins are not going to be adversely affected. Even with the drop-off in health plan enrollment and revenue, they still know how to convert their revenues to profit.”

COVID & Collusion

After several decades in the health insurance business, Potter says he’s rarely surprised by the degree of collusion between the big plans and the government.

But even he was taken aback when the Trump administration announced in April that it was contracting with UnitedHealth Group to oversee and disburse $26 billion in federal relief funds to COVID-stricken hospitals.

Rather than running the money through its usual Medicare and Medicaid payment channels, the government chose UnitedHealth—the country’s largest private, for-profit insurer–to administer and distribute the massive sum to hospitals and clinics that are running aground financially, owing to the impact of COVID.

UNH claims it is not profiting on the deal, and that the $1 million administrative fee that the government is paying will be donated to further hospital relief.

Friends in High Places

In his announcement of this arrangement, Health and Human Services Secretary Alex Azar claimed that UNH was better positioned “to expedite” the distribution of the money to hospitals where it is needed.

Alex Azar, Secretary, Department of Health & Human Services

Potter says he smells a rat.

“The government, through CMS, makes payments to healthcare providers every single day. They’ve been doing it for more than 50 years. Why would you think that a private company could do it more expeditiously when they don’t even do business with all the hospitals in the US?

“They (UNH) are big. But they’re not as big as Medicare. They don’t have as many doctors and hospitals in their networks as does the Medicare program. So why in the world would the federal government turn to a private company that actually has fewer doctors and hospitals in network than Medicare? There’s no logical reason for that, except that it was a favor. It’s an example of what happens when you have friends in high places.”

The insurance industry is one of the largest sources of political campaign funding. United, being the biggest player on the field, doles out a lot of campaign cash on both sides of the aisle.

According to the Center for Responsive Politics’ website, UnitedHealth—through its political action committees and through donations by individual executives—is ranked number 126 in a list of 5,500 biggest Washington lobbyists, and 111th in a list over 19,000 sources of campaign contributions.

Potter points out that President Trump himself, as well as Vice President Mike Pence, CMS Administrator Seema Verma, who was a close advisor to Pence, and many top officials in the administration are, “very favorable to private industry, to private insurance companies.”

Push for Privatization

“They strongly encourage people to enroll in Medicare Advantage plans. They want to convert the Medicare program to a program that is entirely run by the (private) insurance companies. That has long been an objective of a number of Republican politicians. Over the years they just developed relationships with the executives of these big companies, as they have sought to turn more and more of these public programs over to private insurers.”

Steven Parente, of the White House Council of Economic Advisers, is among the people in charge of managing the hospital COVID relief program. Prior to this position, he served as a business consultant to a number of major corporations, including—guess who? UnitedHealth Group.

As reported on the Politico website earlier this year, just a few months after Trump installed Parente in his current HHS post, UnitedHealth made a $1.2 million multi-year donation to Parente’s research center at the University of Minnesota. A curious coincidence, is it not?  

Beyond UNH’s involvement in distributing the money, there are other questionable issues regarding the government’s hospital bail-out plan.

Disbursement of the $26 billion is based on how much hospitals were reimbursed in 2019 under the traditional Medicare Fee for Service programs—that is, Medicare Part A and Part B contracts.

Critics, like Erin O’Malley, senior policy director for America’s Essential Hospitals, is concerned that the plan will direct more money into the hospitals with big private-sector Medicare Advantage contracts, and less into those with high proportions of “traditional” Medicare and uninsured patients.

“We’re worried that by only looking at Medicare fee for service revenues, it could tilt the playing field against some of our members that have a disproportionate share of uninsured as well as Medicaid patients,” said O’Malley, in an interview posted on CNBC in April.

Sheep’s Clothing

Wendell Potter says that in times of crisis—like the current pandemic—insurers go into overdrive trying to make themselves look like good guys, concerned with public well-being.

Case in point, Potter’s former employer– Cigna—and its announcement that it will waive “all customer cost-sharing and co-payments for COVID-19 treatment.”  

Cigna and other major insurers are trying hard to look like “good guys” during the pandemic, with programs to drop cost-sharing on COVID care. But big loopholes mean the rules don’t apply to all plans.

“Our customers with COVID-19 should focus on fighting this virus and preventing its spread,” said David M. Cordani, the company’s president and CEO, whose personal compensation package totaled more than $19 million last year. “While our customers focus on regaining their health, we have their backs. Our teams of experts are working around the clock to support front line health care workers, increase flexibility for hospitals, and deliver greater peace of mind to those we serve.”

Several other major insurers have also waved the banner of altruism by similarly dropping co-pays and cost-shares on COVID-related care. The website for America’s Health Insurance Plans (AHIP), the industry’s biggest trade organization, has a list of all the big insurers and their official responses to COVID.

Dropping co-payments? Sounds generous. Potter says it’s little more than corporate PR.

That’s because if you look at the fine print, you’ll see that the insurers are allowing their corporate customers with self-insured plans to opt out of this philanthropic display.

“In other words, these rules they say they’re putting in place, apply only to the people who are in the so-called “fully ensured” health insurance plans. All their employer customers (ie the self-insured plans) have the opportunity to opt out. Who knows how many are opting out?! There is no way of knowing that. AHIP will not tell you that.”

No Standardization

Most Americans get their insurance via their jobs. Most of the large employers—the big corporations—are self-insured, which means they can opt-out of the insurance industry’s magnanimous offer to eat the copayments.

As a result, ordinary Americans might read the statements on the AHIP site and think that the waived cost-shares apply to them, only to find out that their particular companies have opted out.

Potter says there’s similar variability within the Medicare Advantage plans. “Cigna might be doing it (dropping COVID co-pays). But Aetna might not be doing it. Humana might be doing it, but Anthem might not. So, it really depends on what specific plan you are enrolled in, even if they’re all “Medicare Advantage” plans.

“So, it’s all over the place. There’s no standardization. You cannot believe what these health plans are saying, nor is there any reason to have certainty that they’re going to be doing the right thing for all the people enrolled in their health plans.”

To the extent that insurers really are waiving COVID costs for ordinary Americans, this is a positive step. But rest assured that on the insurance industry’s priority list, the public good comes well below profitability, CEO compensation, and shareholder return.


Nutrients & Phytochemicals to Ease Pulmonary Inflammation

Cryogenic electron microscopy model of NLRP3 inflammasome ring, a key driver of pulmonary inflammation (C&EN/Protein Data Bank)

Pulmonary inflammation has been in the public spotlight since the start of the COVID-19 pandemic. Formerly obscure immunology terms like “cytokine storm” are now common, as we learn more about how the immune system responds to SARS-CoV-2 and other viral pathogens.  

The intense immune reactions seen in severe COVID cases and other forms of Acute Respiratory Distress Syndrome (ARDS) are mediated in part by Inflammasomes–multi-protein complexes found in the cytosol of immune cells, pulmonary endothelial cells, and other epithelial cells.

What are Inflammasomes?

Inflammasomes are typically formed in response to specific stimuli including pathogenic microbes, environmental insults, or inflammatory signaling molecules.  As part of the innate immune system and the body’s first line of defense, inflammasome activation leads to the release of pro-inflammatory cytokines IL-1B and IL-18. In the lungs, IL-1B is one of the most potent inflammatory cytokines, and it is a major factor in ARDS.

In ordinary circumstances, inflammasome activation is a discrete and limited process resulting in a clearance of the triggering noxious stimuli such as infectious pathogens, environmental or metabolic toxins. However, the excessive activation of inflammasomes can result in increased and prolonged cytokine release, chronic inflammation and pulmonary and endothelial damage.

Inflammasome activation also triggers pyroptosis, a rapid form of programmed cell death. Pyroptosis is a highly inflammatory state usually triggered in response to intracellular pathogens.

The good news is that many phytochemicals naturally occurring in certain herbs and plant foods can down-regulate inflammasome activation.

Inflammasome Dysregulation

Computer-generated image of NLRP3 alone (L), NLRP3 bound to NEK7, and a sequence of 11 NLRP3 subunits assembled into an activated inflammasome ring. This inflammasome plays a key role in pulmonary inflammation. (Wu H, et al. Harvard Medical School)

There are many different types of inflammasomes. The NLRP3 subtype is the most prevalent and most well studied pulmonary inflammasome. This has significance in the context of the COVID-19 pandemic because some viruses, including the corona family of viruses, activate the NLRP3 pulmonary inflammasome.

After exposure to a pathogen like coronavirus, NLRP3 Inflammasome activation is initiated in part by an efflux of potassium ions and an influx of calcium ions. At the same time, there is an increase in pro-oxidative Reactive Oxygen Species (ROS) and lysosomal proteases. This is accompanied by activation of NFkB, the nuclear factor that is upstream of a cascade of intracellular pro-inflammatory pathways and macrophage activation.

Combined, these processes create a highly pro-inflammatory environment, with high levels of oxidative stress and proteolytic enzymes, predisposing to thrombus and fibrin formation. At the cellular level, this is war. 

When this response is mobilized, an infection can be quickly neutralized. The inflammatory cascade should then turn off, enabling the body to restore equilibrium.

In situations like we’ve seen with severe COVID and other acute respiratory infections, this cascade does not turn off, resulting in a prolonged cytokine “storm” that can cause serious, sometimes fatal tissue damage.

Inflammasome dysregulation leads to excessive cell death, tissue fibrosis, and ultimately, organ dysfunction.  Chronic diseases such as COPD, auto-immune inflammatory syndromes, Crohn’s disease, Type 2 Diabetes, Alzheimer’s disease, atherosclerosis and cancers are all associated with dysregulation of the inflammasomes, upregulation of NFkB, and other inflammatory cytokines.

Respiratory distress in the context of inflammasome dysregulation is not always responsive to exogenous oxygen therapy. That’s because the alveoli themselves become damaged and dysfunctional. Further, there is also endotheliitis in the capillary beds surrounding the alveoli, leading to hypercoagulation and thrombus formation. The net result is that the alveoli are unable to deliver oxygen to the blood.

This creates a deadly feed-forward cycle, because the resulting hypoxia is itself a signal for activation of the NLRP3 inflammasome.  This is a perfect storm for respiratory failure, severe morbidity, and all too often, death.

Quelling Inflammasome Activation

There are many natural compounds can act as regulators and modulators of pulmonary NLRP3 inflammasome activation and its sequela. Phytochemicals including lectins, flavones, flavonoids, stilbenes, catechins and other phenolic compounds derived from both food and therapeutic plants can modulate the NLRP3 Inflammasome activation and down-regulate inflammatory cytokines IL-1B, TNFa, NFkB as well as ROS.

Curcumin-rich rhizomes of Turmeric (Curcuma longa)

Curcuminoids are lipid soluble polyphenol isolates derived from Rhizoma Curcuma longa (Turmeric). Small amounts of curcuminoids are also found in the rhizomes of Zingiber (Ginger) species. Curcumin is widely studied and has been found to be a negative regulator of NLRP3 inflammasome expression through multiple pathways. It is also a mediator of inflammatory signals including NFkB, TNF-α, and downstream cytokines including IL-1B.

Curcumin’s bright yellow color announces its value as a scavenger of ROS and modulator of oxidative stress. The absorption of curcuminoids from turmeric-rich foods and supplements is enhanced with the addition of black pepper. The most absorbable curcumin supplements are lipid based.

Resveratrol is a stilbene polyphenol present in abundance in the skins of red and purple grapes, and in the plant Polygonum cuspidatum.  It is the trans-resveratrol isomer that is most biologically active.  Resveratrol has been widely studied and like most polyphenols, it scavenges ROS and reduces oxidative stress.

Resveratrol up-regulates the expression of Sirtuin I which is a deacetylase enzyme that inactivates multiple inflammatory genes. Resveratrol also activates AMPK which attenuates NLRP3 inflammasome activation, NFkB transcription, and IL-1B secretion.

Epigallocatechin-3-gallate (EGCG) is the major bioactive polyphenol found in Green Tea (Folium Camellia sinensis).  It inhibits NLRP3 inflammasome activation, and also reduces the expression of NFkB, matrix metalloproteinases, IL-1B, IL-6 and TNF-α. EGCG’s antioxidant properties and ability to scavenge ROS are also well-documented.  A single cup (8 oz or 250 ml) of brewed green tea contains approximately 50-100 mg of EGCG.  EGCG catechin is also available in capsules.

Cruciferous vegetables such as cabbage, bok choi, and broccoli are rich in sulforaphane, which helps down-regulate inflammasome activation

Sulforaphane glucosinolate (SFN) is a natural compound found in cruciferous vegetables. Sulforaphane inhibits activation of multiple inflammasomes including NLRP3. It also reduces IL-1B secretion and NFkB expression, and quenches oxidative stress and ROS.  Food sources include kale, broccoli, broccoli sprouts, Brussel sprouts, cabbage, bok choy, mustard greens, and radishes. 

Sulforaphane is an isothiocyanate produced from a precursor called glucoraphanin, in the presence of the myrosinase enzyme. It is best to lightly cook (steam or sautee) or massage cruciferous vegetables to liberate their phytochemicals. There are a number of supplement products now available that include Sulforaphane, Glucoraphanin, DIM (di-indole-methane) and I3C (indole-3-carbinol) in capsule or powder form. The highest quality products are derived from broccoli sprouts and broccoli seeds.

Quercetin is a flavonoid commonly found in a wide variety of fruits, vegetables and herbs.  It has been shown to block NLRP3 inflammasome activation inhibit damage from ROS and modulate multiple inflammatory pathways and downregulate NFkB expression and  IL1B secretion.  The red skin of apples and purple onions are rich dietary sources of quercetin.  Quercetin as a supplement is not highly absorbable and is best taken with healthy fats and oils or  encapsulated as a lipid phytosome.

Ginsenosides are major active saponin components of Radix Panax Ginseng.  Ginsenosides attenuate NLRP3 Inflammasome activation and NFkB expression. They also reduce IL-1B, IL-18 and TNF-α levels.

Modified Citrus Pectin (MCP) is a low molecular weight dietary fiber derived from the inner peel of citrus fruit. It is best known as a Galectin-3 antagonist.  Galectin-3 is widely found in immune and epithelial cells and it promotes NLRP3 inflammasome activation and pyroptosis. 

While unprocessed food pectin is a large lectin molecule that is not digested or absorbed through the intestinal epithelium, MCP is an enzyme-processed product that yields a small esterified molecule that can be absorbed through the small intestine and enter the bloodstream. By binding and inactivating Galectin-3, MCP down-regulates the activation of the NLRP3 inflammasome, reducing pyroptosis and cell death. It also reduces secretion of inflammatory cytokines IL-1B and IL-6, and matrix metalloproteinases. Further, MCP inhibits fibrin formation minimizing the hypercoagulation and thrombus formation that follows from dysregulated inflammasome activity.

The highest quality MCP nutritional products have the smallest particle size to insure intestinal absorption.

Potassium: Due to the potassium efflux that occurs at the initiation of inflammasome activation, oral potassium repletion makes sense, according to Joe Pizzorno, ND. For patients who follow a plant-based diet, there should be no shortage of potassium ingestion.  However, an elderly, very ill, or hospitalized patient who is not eating normally could be potassium-depleted. 

For such at-risk patients, it is wise to monitor potassium as well as the full range of electrolytes.

Food as Medicine

Cancer is also a chronic inflammatory illness. The selected natural compounds reviewed here also form the core Materia Medica found to shift the tumor microenvironment and the cancer terrain away from inflammation, hypercoagulation, immune suppression, carcinogenesis, proliferation, angiogenesis, and metastasis.  

Many of the natural compounds that influence inflammasome activation are found in plant food. These phytochemicals are pleomorphic multi-taskers and can bind to many different receptors and influence a lot of different pathways and genes at once. Therefore, encourage patients who are concerned about their immune system health to eat a plant-rich, colorful, rainbow diet that includes a variety of herbs and spices. A diet rich in phytochemicals has a powerful impact on long term health and enhances inflammation control. Remind patients that, “Our food is talking to our genes. This is why it matters what we eat.”


Without Effective Meds, Clinicians Explore Nutrition-Based Treatments for COVID

Dance of the Immune CellsNutritional status is a major determinant of COVID-19 risk. Yet public health policy worldwide has given little attention to the role that nutrition, supplementation, and herbal medicine could play in improving individual and community resilience. 

The intense focus on stopping viral spread is sensible and necessary. But without a parallel effort toward strengthening immune system function, enhancing resilience, and mitigating the burden of chronic metabolic disease, people will remain vulnerable to SARS-CoV-2, and any future novel pathogen.

Pharmaceuticals and vaccines—the great hopes of political leaders, and of many citizens—will play important roles in quelling this pandemic. But they are only partial solutions—and they are still a long way off.

“A wealth of mechanistic and clinical data show that vitamins, including vitamins A,

B6, B12, C, D, E, and folate; trace elements, including zinc, iron, selenium, magnesium, and copper; and the omega-3 fatty acids EPA and DHA acid play important and complementary roles in supporting both the innate and adaptive  immune system,” writes UK researcher Philip C. Calder in a recent paper in the journal, Nutrients.

“Deficiencies or suboptimal status in micronutrients negatively affect immune function and can decrease resistance to infections….there can be decreases in the numbers of lymphocytes, impairment of phagocytosis and microbial killing by innate immune cells, altered production of cytokines, reduced antibody responses, and even impairments in wound healing.”

Yet none of this is even part of the international public health dialog. The World Health Organization’s massive multi-nation SOLIDARITY Trial of the “most promising therapies” for COVID includes nothing about nutritional supplementation. The study is looking at the newly-approved antiviral Remdesivir, Chloroquine, Hydroxychloroquine, and a combination of two anti-HIV drugs—lopinavir and ritonavir.

In the absence of definitive drug therapies, practitioners are experimenting with a wide range of supplements, herbal remedies and older, rarely used drugs to try and protect themselves and help their patients deal with COVID.

Here, we review the natural therapies gaining the attention of prominent holistic and functional medicine practitioners and organizations. This list is by no means exhaustive, and the evidence is drawn mostly from studies of acute respiratory distress syndrome (ARDS), and other viral and bacterial respiratory infections. Given that COVID-19 did not even exist 6 months ago, there are few nutritional intervention studies in COVID patients, though several are in the works.

The Institute for Functional Medicine’s COVID-19 Task Force published a useful compendium of recommendations for nutrients and herbs that may:

  • Favorably modulate viral-induced pathological cellular processes.
  • Promote viral eradication or inactivation.
  • Mitigate collateral damage from other therapeutic agents.
  • Promote resolution of collateral damage and restoration of function.
  • Reduce severity and duration of acute symptoms.
  • Support recovery and reduce long-term morbidity and sequelae.

The functional medicine approach is focused, in part, on reducing the virus’ characteristic activation of a branch of the immune system called the NLRP3 inflammasome.

Vitamin C supports immune function in multiple ways: it strengthens epithelial barrier function, fosters growth and function of innate and adaptive immune cells, facilitates white blood cell migration to sites of infection, and increases phagocytosis and production of antibodies.

Ascorbate crystals Brian Johnston Nikon Small World competition Deficiency is clearly associated with increased susceptibility to severe respiratory

Infections (Carr AC, Maggini S. Nutrients 2017). A Cochrane metanalysis of three small studies suggests that Vitamin C supplementation can reduce risk of pneumonia; the effect seems most pronounced in the elderly and those who are deficient at baseline (Hemila H, et al. Cochrane Database Syst Rev 2013). It also reduces duration and severity of upper respiratory tract infections (Hemila H, Chalker E. Cochrane Database Syst Rev. 2013)

The recent Calder paper recommends daily supplemental doses of at least 200 mg/day for healthy people, and between 1-2 g/day for those who are sick. These levels are considerably higher than the US RDAs, which are 75 mg/day for women and 90 mg/day for men, but still within the tolerable upper limit, which is 2 grams.

IFM’s guidance document suggests going up to 3 grams in high-risk individuals. The potential benefits are high, and the risk is very low.

The only COVID-specific studies have been with intravenous ascorbic acid. Data from COVID wards in Shanghai indicate that IV injections of 100-200 mg/kg per day improved oxygenation, reduced mortality, and shortened hospitalizations in COVID patients under ICU care. It also mitigates the characteristic cytokine storms seen in severe COVID cases. Expert guidelines from Shanghai advise giving the IV ascorbate in conjunction with heparin and broad-spectrum protease inhibitors.

The CITRIS-ALI (Vitamin C Infusion for Treatment in Sepsis Induced Acute Lung Injury)

study set the critical care world on fire when it published last January. The study involved 167 ARDS inpatients randomized to IV vitamin C (50mg/kg every 6 hours for 96 hours) or placebo infusion.

The vitamin C infusion did not result in any changes in organ failure scores, c-reactive protein levels, or any of the other primary endpoints. But it did produce a marked reduction in 28-day mortality (30% vs 44%), a greater number of ICU-free days (11 vs 8), and an increased number of hospital-free days (23 vs 16). These findings were statistically significant.

Yet, US hospitals have been slow to embrace IV ascorbate. The Front Line COVID-19 Critical Care Working Group hopes to change that. This physicians’ consortium from critical care centers all over the US advocates a protocol it calls MATH (Methylprednisolone, Ascorbic Acid, Heparin, and Thiamine).

The group recommends IV ascorbate, 3 grams per 100 ml every 6 hours, for 7 days, to counteract the inflammatory damage, and the severe hypercoagulable states typical of COVID. They contend that if implemented early, MATH could save thousands of lives, reduce the need for intensive care and mechanical ventilation.


Vitamin D and its metabolites are, in essence, immunoregulatory hormones. They have direct antimicrobial effects and indirect stimulatory effects on various aspects of the immune system. Calder points out that many types of immune cells have vitamin D receptors. At sufficient levels, the vitamin promotes differentiation of monocytes to macrophages, and increases their ability to destroy pathogens. It increases antigen presentation, but tempers cytokine release, possibly preventing cytokine storms.

Leo Galland, MD, a functional medicine practitioner in New York City, points out that vitamin D is essential for normal function of the Angiotensin Converting Enzyme-2 (ACE-2), and that deficiency impairs ACE-2. This has implications for COVID, in that the virus binds to ACE-2 on the surface of alveolar endothelial cells. An overwhelming of normal ACE-2 activity is one of the hallmarks of the COVID syndrome. Vitamin D supplementation might, potentially, attenuate this.

Vitamin D metabolites prevent excessive expression of inflammatory cytokines while also stimulating expression of anti-microbial peptides from neutrophils, monocytes, natural killer cells, and lung epithelial cells (Cannell JJ, et al. Epidemiology & Infection. 2006).

On a population basis, there is a crude inverse correlation between vitamin D levels and susceptibility to COVID.  In a very recent cross-sectional analysis, Vit D COVID PrevalencePetre Christian Ilie and colleagues showed that COVID prevalence and mortality were both highest in the countries with the lowest mean vitamin D. Portugal, Spain, Italy, and Switzerland were among the countries with the lowest mean vitamin D levels in COVID patients, and this was especially pronounced among the elderly.

Ilie’s findings corroborate a 2013 systematic review by Jolliffe and colleagues showing consistent inverse associations between vitamin D status and risk of upper and lower respiratory infections.

Individual susceptibility may be partially explained by the fact that vitamin D deficiency impairs macrophage production of surface antigens, phosphatase, and H2O2, all of which play key roles in macrophage-mediated defense against pathogens (Abu-Amer Y, Bar-Shavit Z. Cellular Immunology. 1993)

Supplementation can reduce risk of acute respiratory infections (ARI), according to a massive metanalysis by Adrian Martineau of the London School of Medicine & Dentistry, who collaborated with researchers all over the globe to assess the preventive impact of vitamin D.

The Martineau paper, published in the British Medical Journal in 2017, covered 25 randomized vitamin D trials involving nearly 11,000 total patients. Irrespective of dose level or schedule, they found that vitamin D supplementation at any dose level translated into a 12% aggregate reduction in ARI incidence. There was a 19% reduction among people getting daily or weekly doses without bolus dosing.

Subjects with the lowest baseline 25(OH)-D levels benefit the most from supplementation. In people with baseline levels under 25 nmol/L, there was a 70% reduction in ARIs, compared with a 25% reduction among those with baselines above 25 nmol/L.

In reviewing the Martineau data, pulmonologist Roger Seheult notes that the number needed to treat (NNT) with vitamin D to prevent ARIs in a general Vit D Covid Mortality population is about 33, “roughly the same as for aspirin to prevent myocardial infarction.” Among people who are deficient, the NNT is 4, making supplementation a no-brainer.

Seheult, a critical care specialist in Banning, CA, also pointed to The Irish Longitudinal Study on the Aging (TILDA), a prospective study of more than 8,000 Irish adults over age 50. The data suggest that at doses of 400 IU per day for low-risk individuals, and 800-1,000 IU per day for deficient and high-risk patients, vitamin D3 could reduce the prevalence of (non-COVID) chest infections by 50%.

Researchers at the University of Grenada recently launched a 10-week study to assess the impact of single 25,000 IU bolus dose of vitamin D in a cohort of 200 individuals with confirmed SARS-CoV-2 infections.

Calder and colleagues note that doses aimed at reducing respiratory infections are generally higher than the US RDA’s which range from 400–800 IU (depending on age).  They recommend a daily intake of 2000 IU vitamin D3 per day to optimize immune function. IFM’s guidelines suggest going as high as 5,000 IU/day.

In a MedCram video detailing his personal supplementation protocol, Seheult—who treats COVID patients every day—says he sees little harm in upping the dose, especially for clinicians exposed to SARS-CoV-2. He’s taking 2,500 IU daily.

It is worth noting that the TILDA data show a strong inter-relationship between vitamin D deficiency, age, and obesity—all three are known risk factors for COVID morbidity and mortality, and they may be inter-related. Obese people were more likely than non-obese to be deficient, and this difference was more pronounced in people over the age of 70.


The IFM’s guidelines recommend supplementation with vitamin A, owing to its regulatory role in cellular and humoral immune responses. It affects T-helper cell function, production of secretory IgA, and regulates cytokine production.

In a review paper on potential interventions for COVID, researchers at the Shengjing Hospital in Shenyang Liaoning, China, point out that viral infections like measles tend to be worse in vitamin A-deficient children. Retinoids appear to, “inhibit measles replication is upregulating elements of the innate immune response in uninfected bystander cells, making them refractory to productive infection.” (Zhang L, Liu Y. J Med Virol. 2020)

Vitamin A supplementation can reduce morbidity and mortality in a range of human infectious diseases including measles-related pneumonia and HIV/AIDS.

IFM’s COVID recommendations suggest supplementation with 10,000 – 25,000 IU per day, though there are no clinical studies to support that.

Dr. Galland is more cautious. In his Coronavirus Handbook, he reminds colleagues that vitamin A (retinoids) can cause liver toxicity at high doses. He recommends supplements only if a patient shows low blood levels.


In their recent paper, Zhang and Liu point out that people with deficiencies in B vitamins have weaker overall immune system responses to a range of pathogens.

In vitro experiments with human plasma show that vitamin B2 (riboflavin) can reduce the titers of MERS-CoV—the coronavirus pathogen that killed roughly 35% of all people infected with it back in 2012 (Kiel SD et al. Transfusion. 2016)

In mouse experiments and in vitro studies, vitamin B3 (nicotinamide) enhances the destruction of Staphylococcus aureus via a myeloid-specific transcription factor (Kyme P, et al. J Clin Investigation. 2012).

There is not a lot of specific evidence to make formal recommendations for B vitamins to prevent or treat COVID. But given their central role in hundreds of metabolic reactions, it makes sense to consider them, especially for elderly and at-risk individuals.

Several recent studies suggest that intracellular levels of nicotinamide adenine dinucleotide (NAD+), a vital metabolic co-factor, are depleted by infectious stressors, particularly by viral infections, and that supplementation to restore NAD+ may be beneficial. This phenomenon has been seen with a number of human viruses.

ARDS is characterized by a massive oxidative/nitrosative stress following viral entry into endothelial cells. This oxidative burst ultimately leads to apoptosis and necrosis due to NAD+ and ATP depletion.

In a preprint issued in March, geneticist Shirin Kouhpayeh and colleagues contend that NAD+ depletion “addresses all questions” in the COVID-19 infection process. They suggest that many of the pulmonary features of COVID, as well as the accompanying fatigue mood disorders, are due to depletion of NAD+, ATP, and serotonin—all of which depend on levels of vitamin B3, or its precursors like L-tryptophan.

Supplementation strategies aimed at boosting NAD+ might ameliorate the symptom burden. One possible approach is supplementation with nicotinamide riboside (NR)—an NAD precursor that can increase cellular NAD+ levels without causing flushing or inhibiting sirtuins.


Vitamin E compounds play a role in maintaining strong cellular immunity, particularly T-cell function, and especially in elderly people. T-cell decline is one of the most common features of immunosenescence.

“Both animal and human studies suggest that intake above currently recommended levels may help restore T-cell function which becomes impaired with aging,” reported Tufts University researchers Simin Meydani and Dayong Wu. “This effect of vitamin E can be accomplished by directly impacting T cells as well as indirectly, by inhibiting production of prostaglandin E2, a T cell-suppressing lipid mediator known to increase with aging.” (Wu D, Meydani SN. Endocr. Metab. Immune Disord. Drug Targets 2014).

Though there are not yet any COVID studies of vitamin E, data from earlier studies of other respiratory infections suggest that it might be beneficial. A randomized controlled trial of 617 residents of 33 Boston area nursing homes, daily supplementation with 200 IU vitamin E per day produced small but significant reductions in incidence of upper respiratory tract infections compared with placebo treatment (Meydani SN, et al. JAMA. 2004). 

In 2009, De la Fuente and colleagues showed that at that same dose of 200 IU per day, vitamin E improved natural killer cell activity, neutrophil chemotaxis and phagocytosis, and mitogen-induced lymphocyte proliferation in elderly men and women (De la Fuente M, et al. Free Radical Res. 2009).


Omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may have a role in quelling the inflammatory response following infection with pathogens like SARS-CoV-2.

At the site of inflammation, EPA and DHA are enzymatically converted to compounds known collectively as specialized pro-resolving mediators (SPMs). These are a family of naturally occurring lipid mediators that play a crucial role in switching off the inflammatory response.

They do not block the initial inflammation phase, which is a desirable and usually beneficial response to infection or sudden injury. Rather, the SPMs down-regulate the process to resolve the inflammation once it has served its purpose. They function as “resolution agonists” targeting the immune cells that mediate the inflammatory response. By binding to specific cellular receptors, particularly the types known “G-protein coupled receptors,” SPMs modify cell behavior to promote resolution.

Calder and colleagues note that omega-3 deficiencies are associated with poor resolution of inflammation. “This could be very important in the context of severe COVID-19 which manifests as uncontrolled inflammation, the so-called cytokine storm linked with acute respiratory distress syndrome (ARDS).”

SPMs formed from EPA and DHA appear to be protective, at least in animal models of ARDS.

A recent Cochrane review of 10 clinical trials involving more than 1,000 hospitalized ARDS subjects did show significant reductions in mortality, ventilator days, and ICU lengths of stay in patients given tube-feeding formulas containing supplemental EFAs versus those given standard formulas.

The trial designs, trial quality, and EFA levels were so variable across the 10 studies that the Cochrane authors dismissed the findings, stating that it is unclear whether use of omega-3s confers any benefits in this context (Dushianthan A, et al. Cochrane Systematic Review. 2019).

None the less, Dr. Calder, who was one of the Cochrane authors, recommends intake of 250 mg/day of EPA + DHA for mitigating COVID risk.


The value of zinc supplementation in preventing or mitigating viral infections is a contentious subject. Zinc is important for maintenance and development of cells in both the innate and adaptive immune systems. Deficiency impairs formation, activation, and maturation of lymphocytes, disturbs cytokine signaling, and weakens innate host defense, according to researchers at Aachen University Hospital.

A 2010 metanalysis of 10 randomized clinical trials involving a total of nearly 49,500 children concluded that routine zinc supplementation at doses ranging from 20 – 140 mg per week, reduced the incidence of acute lower respiratory infections.

The IFM COVID Task Force contends that zinc favorably modulates innate and adaptive immune system responses, and attenuates viral attachment, and replication. The guidelines advise supplementation with oral zinc acetate, citrate, picolinate, or glycinate, at levels of 30–60 mg daily, in divided doses, or as zinc gluconate lozenges.

In January, however, Finnish researchers questioned the efficacy of zinc acetate lozenges. They studied 253 City of Helsinki employees who self-identified as susceptible to severe URIs. Of the total cohort, 88 (35%) developed URIs during the study period, and they were more or less evenly divided between those randomized to placebo, and those using zinc lozenges six times daily for five days, for a total zinc acetate dose of 78 mg/day.

There were no differences between the groups in duration of URI symptoms or recovery rates (Hemila H, et al. BMJ Open 2020).

In his Coronavirus Handbook, Dr. Galland is skeptical about routine zinc supplementation.

“Zinc has been advocated at doses of 30 to 75 milligrams per day for its alleged direct anti-vital effects and for its inhibition of certain enzymes involved in viral transport and replication. This advice ignores the physiology of zinc. Levels of zinc in plasma, even when they are low, are about 10 times greater than those needed for inhibition of viral enzymes. The concentration of zinc inside cells is over 200 times higher than needed.”

He added that, “there is no way that zinc supplementation will impact the level of free intracellular zinc. But high dose zinc supplementation will produce deficiency of copper, and copper is a natural inhibitor of Furin.” The latter is an enzyme produced by all human cells, that SARS-CoV-2 hijacks in order to bind to the ACE-2 receptors on endothelial cells. Galland added that zinc supplementation raises the risk of bowel overgrowth with Clostridum difficile. 

He believes supplementation only makes sense if testing shows serum levels to be low.


NAC is a major promotor of glutathione production, and there’s some evidence that it can mitigate the severity of viral infections. IFM’s Task Force recommends 600-900 mg of oral NAC twice daily.

Italian researchers studied the impact of 600 mg NAC, twice daily for six months versus placebo in a cohort of 262 individuals, most of whom were over 65 years of age. They report significant reductions in frequency and severity of influenza episodes, as well as fewer bedridden days in the NAC group. Local and systemic symptoms were sharply reduced, and though the frequency of seroconversion was similar in the two groups, only 25% of the virus-infected NAC patients became symptomatic, versus 79% in the placebo group (DeFlora S et al. Eur Respir J. 1997).
