Small intestinal bacterial overgrowth

A medical condition characterized by an excessive growth of bacteria in the small intestine, which is typically low in bacterial presence compared to the large intestine. This overgrowth can result in symptoms such as bloating, diarrhea, abdominal pain, and malnutrition, often caused by factors like motility disorders, structural abnormalities, and certain medical conditions. SIBO primarily affects individuals with underlying gastrointestinal issues or those who have undergone surgeries that alter the normal function of the small intestine.
