Healing IBS and Other Gut Issues with the Thyroid Pharmacist

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.
