Your gut bugs may predict chemo diarrhea risk
NCT ID NCT04751448
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores how the bacteria in your gut and what you eat can influence chemotherapy-related diarrhea in colon cancer patients. Researchers will analyze stool samples and diet surveys from about 11 people receiving FOLFOX treatment. The goal is to create a tool that predicts who is at higher risk for this side effect, helping doctors personalize care.
