What is it?

Small intestinal bacterial overgrowth (SIBO) is a condition characterized by an increase in the bacterial population in the small intestine, especially bacteria that are not commonly found in that part. SIBO typically occurs after a surgery or an illness which leads the passage of food and waste to slow down, creating good ground for bacteria to develop. These bacteria may cause diarrhea, weight loss and malnutrition. SIBO may also be caused due to intestinal structural problems such as adhesions and diverticulosis.
