This simple, non–invasive, gastrointestinal test detects bacterial overgrowth in the small intestine, often referred to as BOSI or SIBO. Small intestine bacterial overgrowth (SIBO) is a common gastrointestinal disorder that often underlies chronic gastrointestinal symptoms of maldigestion and malabsorption, including bloating, gas, diarrhea, irregularity, and abdominal pain.
Normally, far fewer bacteria inhabit the small intestine than the ample growth found in the colon. Gastric acid secretion and intestinal motility keep the small intestine relatively free of bacteria. However, a wide range of abnormalities and malfunctions can encourage bacteria to multiply in the small intestine causing SIBO/BOSI. The most common causes of SIBO/BOSI relate to a decrease in the production of hydrochloric acid or pancreatic enzymes, thereby creating an unsterile environment for the small intestine.
