In this discussion, Ally Scheve, a third-year medical student, teams up with Dr. Navin Kumar, a gastroenterologist, to unravel the complexities of Small Intestinal Bacterial Overgrowth (SIBO). They delve into the pathophysiology behind SIBO and how bacterial growth triggers uncomfortable GI symptoms like gas and bloating. Dr. Kumar highlights how nutritional deficiencies, particularly B12, arise from bacterial interference and identifies key risk factors, including altered GI motility and the impact of proton pump inhibitors on SIBO development.
