In this episode, Dr. Eric sits down with gut health expert Lindsey Parsons to explore the deeper root causes behind SIBO—especially post-infectious IBS. Lindsey shares her personal journey from food poisoning to chronic gut issues and autoimmune conditions, eventually leading her to specialize in helping others heal complex digestive disorders.

They dive into what really drives recurrent SIBO, explaining how an autoimmune response triggered by food poisoning can damage the migrating motor complex, leading to ongoing bacterial overgrowth. Lindsey breaks down the differences between hydrogen and methane SIBO, the role of fungal overgrowth (SIFO), and why many traditional approaches fail to provide lasting results. The conversation also covers testing options like the IBS Smart test, limitations of breath testing, and how to better assess the gut microbiome.

You’ll also learn about effective treatment strategies, including when to use antibiotics versus herbal antimicrobials, the emerging use of MSM, the controversy around berberine, and the critical role of prokinetics in long-term management. If you want a clearer, more balanced understanding of why SIBO keeps coming back and how to manage it effectively, you’ll get a lot out of this episode.

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.
