For more than 30 years in practice, Dr. Dean Mitchell never used hair analysis in his diagnostic workups. He wasn’t convinced it was reliable or clinically useful. That changed after reading a New York Times investigation into wildfire-exposed families in Los Angeles and the role hair testing played in uncovering toxic exposure patterns.

In this conversation, Dr. Mitchell speaks with Dr. Manish Arora, Vice Chair of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai and Founder of LinusBio. Dr. Arora explains how a single strand of hair can function as a “molecular movie,” capturing hourly biological data over time rather than the single snapshot provided by blood tests.

They discuss heavy metals like lead and mercury, environmental toxins such as BPA and phthalates, wildfire exposure, air pollution, and how hair analysis can reveal patterns that traditional testing may miss. The episode also explores exposomics, oxidative stress, women’s health, Parkinson’s disease, and Dr. Arora’s development of a rule-out test for autism spectrum disorder.

If you have ever wondered how environmental exposures affect your long-term health, this conversation offers a fascinating look at how cutting-edge science is turning hair into one of medicine’s most powerful diagnostic tools.

Toxic mold, long COVID, vaccine injury, mast cell activation, and the patients who seem to react to everything. Dr. Dean Mitchell sits down with Dr. Keith Berkowitz and Dr. Ariana Ventrella for a wide ranging conversation about why complex cases keep getting more complex, why the nervous system and fight or flight can become the rate limiting factor in healing, and what it looks like to rebuild safety and tolerance over time.

They also get into where medicine got stuck during COVID, why timing matters with steroids and other treatments, and the questions many patients still have about boosters and natural immunity.

Then Dr. Ventrella walks through Clarity TX, an AI powered clinical tool designed to help clinicians evaluate supplement evidence, reduce polypharmacy, flag safety issues, and build more individualized protocols without losing the human part of care.

Vaginal discomfort is one of the most common reasons people seek care, and Dr. Dean Mitchell and Dr. Kate McLean get honest about why vaginitis is so often misdiagnosed and why symptoms so often come right back after treatment.

They break down how most office based testing works, why standard PCR panels can miss key bacteria like Gardnerella, and how Evvy’s next generation sequencing approach looks at the full vaginal microbiome instead of a short checklist. The conversation also covers what a healthy vaginal microbiome actually looks like, why lactobacillus dominance matters, and why higher vaginal microbiome diversity is often linked with worse fertility and pregnancy outcomes.

A major shift in thinking comes up around bacterial vaginosis and recurrence. New research suggests male partners may need treatment too, and they explain how Evvy’s treatment model addresses both the microbiome and reinfection risk.

They also walk through how Evvy’s at home test works step by step, what it costs, how results are reviewed through an asynchronous clinician consult, and when symptoms should prompt an in person medical evaluation.

A healthy 65-year-old man eats raw tuna and within an hour ends up in the emergency room with dangerously low blood pressure, severe gastrointestinal symptoms, and EKG changes that look like a heart attack. What happened next surprised even his doctors.

Dr. Dean Mitchell walks through a real case published in the Journal of the American Medical Association that highlights a lesser known but serious foodborne illness called scombroid poisoning. Often mistaken for an allergic reaction or cardiac event, this condition is caused by high levels of histamine in improperly stored fish and can lead to shock, respiratory failure, and ICU level illness.

This episode breaks down how scombroid poisoning happens, which types of fish are most commonly involved, why it can be so hard to detect, and what subtle clues may warn you that something is wrong before symptoms spiral. Dr. Mitchell also explains why this reaction is not a true fish allergy and what to be cautious about when eating seafood at restaurants, buffets, cruises, or outdoor events.

A fascinating and important listen for anyone who eats fish and wants to stay informed and safe.

Today’s conversation steps a little outside the usual hardcore medical lane, but it may be just as important. Dr. Dean Mitchell explores medical intuition and the big question many listeners are already asking: is it believable, or is it BS?

His guest is Catherine Carrigan, a professional health intuitive and holistic healer, and she explains what a medical intuitive actually is and how she approaches healing across what she calls five levels: physical, energetic, emotional, mental, and spiritual. They talk about how her work can complement traditional medicine, why environment and nutrition matter, and why healing can get blocked when someone is not truly willing to get well.

You’ll also hear about her personal journey through illness, her background in a medical family, and what led her from conventional paths into natural healing, intuition, and a long running spiritual practice that shapes how she helps clients.

Are cancer detecting blood tests finally ready for real world use? Dr. Dean Mitchell sits down with Dr. Eric Klein, a distinguished scientist at GRAIL and former Cleveland Clinic chair, to walk through the promise and the limits of the Galleri multi cancer early detection blood test. They break down how the test looks for cancer related DNA using methylation patterns, why it can often predict where a cancer started, and what happens next if a cancer signal is detected. You’ll also hear how Galleri fits alongside standard screenings like mammograms, colonoscopy, PSA, and Cologuard, plus a clear explanation of sensitivity versus positive predictive value and why false positives matter. They also explore who may benefit most from testing, why age is the biggest risk factor, what the real false positive rate looks like, and how long a negative result may offer peace of mind.

Dizziness is one of the most common symptoms patients experience, yet it is also one of the most misunderstood. In this episode of The Smartest Doctor In The Room, Dr. Dean Mitchell is joined by neurologist and dizziness specialist Dr. Amir Kheradmand to explain what dizziness really means, why it is so difficult to diagnose, and when it may signal a more serious condition.

The conversation breaks down the key differences between dizziness, vertigo, and lightheadedness, why medications like meclizine are often outdated, and how careful history taking and eye movement exams can help determine whether symptoms are coming from the inner ear or the brain. Dr. Kheradmand also discusses vestibular migraine, stroke risk, chronic dizziness, medication side effects, and why CT scans frequently fail to identify the true cause.

This episode offers clear guidance for patients seeking answers and valuable insight for clinicians looking to improve how dizziness is evaluated and treated.

Join Dr. Dean Mitchell on The Smartest Doctor In The Room as he reflects on more than 25 years in medical practice and explores how medicine has evolved and what should never be lost along the way. From handwritten charts and prescription pads to electronic records, telehealth, and AI driven information, Dr. Mitchell shares firsthand insights into how technology has transformed the doctor patient relationship for better and for worse.

In this thoughtful conversation, he discusses the importance of eye contact, physical exams, careful history taking, and genuine human connection in an era of screens, shortcuts, and online medical advice. Dr. Mitchell also addresses the risks of self-diagnosis, social media health trends, and direct to consumer medical services while encouraging patients to stay informed without trying to be their own doctor.

This episode is a timely reminder that while medicine continues to advance, trust, connection, and listening remain at the heart of truly effective care.

In this episode of The Smartest Doctor In The Room, host Dr. Dean Mitchell sits down with world-renowned allergist and immunologist Dr. Thomas Platts-Mills to explore the shocking true story behind a healthy airline pilot who died after what seemed like a simple steak dinner. The cause was not choking or food poisoning. It was a delayed, deadly allergic reaction from a condition many people and even many doctors still overlook.

Dr. Mitchell and Dr. Platts-Mills walk listeners through the mystery of alpha gal syndrome, also known as red meat allergy syndrome, a unique allergy triggered by tick bites that can cause severe reactions hours after eating beef, pork, lamb, venison, and other red meats. They discuss how this condition was discovered in the 2000s, its link to the lone star tick, why abdominal pain is often the main and most confusing symptom, and why standard autopsies may completely miss fatal anaphylaxis.

You will hear how epidemiologic clues, patterns across the southern United States, and unexpected reactions to the cancer drug cetuximab helped Dr. Platts-Mills and his team uncover that alpha gal, a sugar molecule found in mammalian meat and certain medications, can become a target for IgE antibodies. The conversation also explains how to interpret alpha gal blood test levels, why total IgE matters, when tryptase can help confirm severe reactions, and how alcohol, NSAIDs, and exercise can make symptoms worse.

Dr. Mitchell and Dr. Platts-Mills also touch on related allergy puzzles, including pork cat syndrome, dust mite cross reactivity with shellfish, and how children and adults may present differently. If you or your patients have unexplained nighttime abdominal pain, hives, or severe reactions hours after a steak dinner or other red meat, this episode will help you think like a medical detective and consider alpha gal syndrome as a possible answer.
