Small Intestinal Microbial Overgrowth: A Conversation with Dr. Vincent Pedre, MD IFMCP All microbes, not just bacteria, can contribute to problems in the small intestines. Today more than ever, we see patients with hard-to- treat gut problems. Dr. Pedre brings his own gut healing journey and Functional Medicine background to the table to talk to us about treating patients with SIBO-or as he likes to call it-SIMO, which encompasses microbes beyond bacteria and includes the oft-overlooked fungal piece of the puzzle. Dr. Pedre shares loads of treatment pearls from his gut-centric practice, but reminds us that any protocol must be individualized for the person sitting in front of us.
