In this episode of The Turd Nerds, the Turds are joined by  ⁠Dr. Mark Davis, ND ⁠and we take a deep dive into the strange but powerful world of fecal microbiota transplantation (FMT)—what happens when you transplant an entire microbial ecosystem into the human gut and why it can be so effective for certain diseases. We explore why FMT is nearly curative for C. difficile, how dosing and delivery affect outcomes in ulcerative colitis and Crohn’s disease, and share striking clinical stories of severe inflammatory bowel disease improving after repeated treatments.
