In this episode, Dr. Eric Osansky talks with returning guest Dr. Izabella Wentz about her new book, IBS: Finding and Treating the Root Cause of Irritable Bowel Syndrome. Drawing from both personal experience and clinical insight, Dr. Wentz explains why IBS is often more than just a stress-related diagnosis and how it can serve as an early warning sign of deeper imbalances, including thyroid autoimmunity.

The conversation explores the difference between IBS and inflammatory bowel disease, why some people diagnosed with IBS may actually have celiac disease or IBD, and the many possible root causes behind chronic digestive symptoms. Dr. Wentz discusses food reactions, SIBO, parasites, H. pylori, medications, nutrient deficiencies, thyroid hormone imbalances, stress, and lifestyle factors that can all play a role in gut dysfunction. She also shares why testing matters, why symptom relief is not the same as true resolution, and why approaches like the low FODMAP diet may only be a short-term tool.

This episode gives listeners a broader, more practical understanding of how gut issues connect with immune dysregulation and thyroid health. If you want a clearer, more balanced understanding of IBS, IBD, and what these digestive symptoms may really be telling you, you’ll get a lot out of this episode.

In this Q&A episode, Dr. Eric dives into the powerful connection between gut health and thyroid function. Recorded during a Substack livestream for his Healing Graves’ Naturally newsletter, he begins by explaining why the gut is such a central player in thyroid autoimmunity. With most immune system cells residing in the gut and about 20% of thyroid hormone conversion occurring in the gut microbiome, maintaining gut health is critical for those dealing with Graves’ disease, Hashimoto’s, or other thyroid conditions.

Throughout the episode, Dr. Eric answers listener questions about gut testing, including when to use comprehensive stool tests, SIBO breath tests, or organic acids testing. He also discusses leaky gut testing, parasites, H. pylori treatment options, histamine intolerance, and how gut imbalances can contribute to symptoms like bloating, gas, and constipation. He explains how diet, stress management, and proper digestive support can play a role in restoring gut balance.

Listeners will also learn about natural approaches to supporting stomach acid levels, the role of fiber in producing beneficial compounds like butyrate, and whether sweeteners like stevia or monk fruit affect the gut microbiome. If you want a clearer, more balanced understanding of the gut-thyroid connection and practical answers to common gut health questions, you’ll get a lot out of this episode.

In this episode, Dr. Eric talks with certified nutritionist and menopause specialist Leah Vachani about blood sugar imbalances, insulin resistance, and how these issues often show up long before a diagnosis of prediabetes or type 2 diabetes. Leah shares how her work with women in perimenopause and menopause led her to see blood sugar as a major missing piece in hormone health, energy, sleep, and weight regulation.

Together, they explore why stress, poor sleep, processed foods, and hormone shifts can all contribute to unstable blood sugar. Leah also explains how continuous glucose monitors can help people see their individual patterns more clearly, from food triggers to stress spikes, while also discussing the limits of CGMs, fasting insulin, A1C, protein intake, apple cider vinegar, intermittent fasting, and exercise.

This conversation gives listeners a practical, realistic look at how to support better metabolic health without chasing perfection. If you want a clearer, more balanced understanding of blood sugar imbalances and insulin resistance, you’ll get a lot out of this episode.

In this Q&A episode, Dr. Eric answers listener-submitted questions all about thyroid antibodies—what they are, why they matter, and how they impact both Graves' disease and Hashimoto's thyroiditis. He begins by clarifying the three main thyroid antibodies—TPO, TSI/TRAB, and thyroglobulin antibodies—and explains why understanding these markers is critical when assessing true remission.

Throughout the episode, Dr. Eric addresses common concerns such as: Can you be in remission if antibodies are still positive? How often should antibodies be tested? Can diet alone normalize them? He also explores the role of environmental triggers, gut health, gluten, iodine, and even supplements like selenium, black seed oil, and low-dose naltrexone (LDN). You’ll hear practical guidance on why antibodies fluctuate, what “optimal” really means (not just “within range”), and why many conventional endocrinologists don’t routinely monitor these markers.

If you’re confused about your antibody results—or wondering why you relapsed after being told you were “in remission”—this episode will help you connect the dots. If you want a clearer, more balanced understanding of thyroid antibodies and what they really mean for your recovery, you’ll get a lot out of this episode.

We take 20,000 breaths a day… but rarely do we stop to consider what we’re actually breathing in.

I recently sat down with indoor air quality expert Michael Rubino to have a thoughtful, eye-opening conversation about mold, hidden water damage, and why so many homes; old and new, may be affecting our health more than we realize.

We covered a lot in this conversation from why mold is often missed (even in newer homes), to the difference between a basic home inspection and a true mold inspection, to how dust testing and mycotoxin testing can sometimes help connect the dots. We also talked about practical steps like HVAC maintenance, proper remediation, and when it makes sense to go deeper versus when not to overreact.

Mental health challenges are often an overlooked part of thyroid and autoimmune disease and that matters more than most people realize.

This episode explores the connection between mental health and thyroid autoimmunity, and why symptoms like anxiety, low mood, or brain fog are often biologically influenced, not just emotional. I walk through how thyroid hormone imbalances, inflammation, and nervous system regulation can affect mental well-being, including the role of the gut. We also look at how chronic stress and trauma can contribute to both thyroid issues and mental health symptoms. The focus is on a balanced, whole-body approach that prioritizes safety, individuality, and root causes rather than quick fixes.

Tune in to better understand why mental health symptoms are so common in thyroid and autoimmune disease and what that connection really means.
