Adhesions caused by previous abdominal surgery.History of radiation therapy to the abdomen.Crohn's disease, intestinal lymphoma or scleroderma involving the small intestine.An abnormal passageway (fistula) between two segments of bowel.A structural defect in the small intestine.Risk factorsįactors that increase your risk of SIBO include: The breakdown products following bacterial digestion of food can also trigger diarrhea. The bacteria may produce toxins as well as interfere with the absorption of nutrients. But in SIBO, stagnant food in the bypassed small intestine becomes an ideal breeding ground for bacteria. Unlike your large intestine (colon), your small intestine normally has relatively few bacteria due to rapid flow of contents and the presence of bile. The small intestine is where food mixes with digestive juices and nutrients are absorbed into your bloodstream. The small intestine is the longest section of your digestive tract, measuring about 20 feet (6.1 meters). Why small intestinal bacterial overgrowth (SIBO) develops
