In this episode, host Alyssa Simpson is joined by GI psychologist and gut-brain expert Dr. Navidi to explore one of the most overlooked drivers of chronic digestive issues: the gut-brain connection.

They dive into a category of conditions known as Disorders of Gut-Brain Interaction (DGBIs)—which include IBS, bloating, reflux, functional constipation, nausea, and more. Millions live with these diagnoses without realizing their symptoms are being driven, not just by food, but by nervous system dysregulation. If your symptoms persist even after eliminating triggers, trying meds, or running every test, this episode explains why—and what to do next.
