Run the List SIBO Part I: Clinical Presentation
23 snips
Nov 3, 2025 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.

Episode notes
Mucosal Colonization Causes Osmotic Diarrhea
- Bacteria lining the mucosa interfere with nutrient absorption and create an osmotic watery diarrhea.
- Severe cases disrupt fat absorption and can cause steatorrhea with greasy, hard-to-flush stools.
SIBO Can Cause Low B12 and High Folate Labs
- Small intestinal bacteria can steal vitamins like B12 and iron, causing deficiencies in the host.
- Some bacteria produce folate, so labs may show low B12 with elevated folate in SIBO patients.
Use B12 and Folate Labs As Clues
- Check B12 and folate when you suspect SIBO because the pattern can support the diagnosis.
- A low B12 with high folate increases your index of suspicion for SIBO.
