83: The Gut-Autoimmune Connection: Breaking the Cycle of Leaky Gut & Chronic Illness | Dr. Vincent Pedre
Thyroid Pharmacist Healing Conversations with Dr. Izabella WentzShow Notes
In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz interviews functional medicine physician Dr. Vincent Pedre about the hidden root causes of IBS, gut inflammation, and chronic digestive symptoms that often precede autoimmune disease.
Together, they explore how stress physiology, nervous system dysregulation, environmental toxins, mold exposure, microplastics, and mitochondrial dysfunction can damage the gut – even in people who are already gluten-free and eating “clean.” Dr. Pedre also debunks common myths about coffee and gut health, sharing how high-quality, clean coffee can be enjoyed without triggering reflux or inflammation.
What you’ll learn in this episode:
Why IBS is often the first warning sign of deeper immune dysfunction. Dr. Pedre explains how years of gut inflammation can dysregulate the immune system, increase intestinal permeability, and eventually contribute to autoimmune conditions like Hashimoto’s – long before labs reveal antibodies.
How stress and nervous system dysregulation quietly sabotage digestion – even when you feel “fine.” Chronic stress suppresses vagal tone, lowers stomach acid and enzyme production, and slows gut motility. Your body always tells the truth.
The hidden gut disruptors most people never test for. Mold exposure, parasites, yeast overgrowth, microplastics, and environmental toxins can damage the gut lining and microbiome, even without classic digestive symptoms.
Why elimination diets don’t always lead to true healing. Removing foods can reduce symptoms, but true healing often requires repairing the gut barrier, addressing toxin load, supporting mitochondria, and calming the nervous system.
The truth about coffee, gut health, and thyroid symptoms. Coffee itself isn’t the enemy – poor-quality beans, mold contamination, pesticides, over-roasting, and plastic exposure are. Dr. Pedre shares information on coffee that is cleaner and gentler on the gut.
How targeted therapies can dramatically speed gut healing. Dr. Pedre shares how phospholipids, peptides, sauna therapy, and mitochondrial testing are helping patients tolerate foods again – often in months instead of years.
Tune in to learn how to heal your gut at the root – and reclaim your health.

In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz speaks with Dr. Efrat LaMandre (Dr. E) about medical gaslighting, why it happens, and how patients can change their approach to ensure they get the right care. Dr. E. explains why doctors may seem dismissive if they don’t find anything on lab tests, why patients can unintentionally dismiss their own symptoms, and how to communicate in a way that healthcare providers understand. She also shares practical strategies for self-advocacy and how to find answers when a doctor’s visit doesn’t bring the clarity you’re certain you need.
In this episode of Thyroid Pharmacist Healing Conversations, Dr. Izabella Wentz speaks with Dr. Richard Horowitz, an integrative physician who has spent more than 40 years working with complex chronic illness, including Lyme and tick-borne diseases. His work eventually led him to develop the MSIDS model, or Multiple Systemic Infectious Disease Syndrome, which looks at 16 different factors that may contribute to chronic illness rather than focusing solely on a diagnosis or individual symptoms.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz speaks with hormone expert Dr. Jolene Brighten about why ADHD is so often missed in women and how hormonal changes throughout a woman’s life can influence the way ADHD symptoms show up. From puberty and hormonal birth control to postpartum, the menstrual cycle, perimenopause, and postmenopause, they explore why some women may not recognize their neurodivergence until midlife, and why understanding how the brain works can be a powerful first step toward finding the right tools and support.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Erin Kinney, naturopathic doctor and author of The Cortisol Cure. She offers a fresh perspective on cortisol and its role in energy, stress, and healing. Rather than viewing cortisol as a hormone that is always “bad” and needs to be lowered, Dr. Kinney explains why understanding how the body uses and replenishes cortisol can change the way we approach burnout, chronic stress, and autoimmune health.
In this episode of the Thyroid Pharmacist Healing Conversations podcast, Dr. Izabella Wentz interviews Dr. Miles Nichols, DAOM, MSOM, LAc, founder of Medicine With Heart Clinic and the Medicine With Heart Institute. Dr. Miles shares his personal Hashimoto’s healing journey, including his experience with debilitating fatigue and brain fog despite being told that his initial testing looked “normal.” His search for answers ultimately led him to look beyond conventional thyroid markers and uncover several potential root causes contributing to his symptoms.
