Episode 71: The Root Cause of IBS — Interview with Izabella Wentz, PharmD What if IBS isn’t a true diagnosis—but a placeholder? What if bloating, cramping, urgency, constipation, diarrhea, and food reactions aren’t signs that your body is “too sensitive,” but clues that something specific and treatable is being missed? In this episode of the Autoimmune Wellness Podcast, I’m joined by Dr. Izabella Wentz, integrative pharmacist, bestselling author, and longtime leader in the root-cause approach to chronic illness.

In this episode, you’ll learn: Why IBS is often a “label,” not a root cause The research showing most IBS cases have identifiable, treatable drivers How IBS can precede autoimmune disease by 5–10+ years The role of intestinal permeability in autoimmunity When IBS may actually be SIBO, celiac disease, IBD, enzyme dysfunction, or something else The difference between IBS and IBD—and red flags you shoul…
