Small Intestine Bacterial Overgrowth Syndrome (SIBO)

Small Intestine Bacterial Overgrowth Syndrome (SIBO) is defined as excessive bacteria in the small intestine. While bacteria naturally exists throughout your digestive tract, the small intestine has relatively low levels of bacteria; its main purpose is to digest and absorb food into the body. The highest concentration of bacteria is normally in the colon. When the small intestine has an overgrowth of bacteria, absorption of vital nutrients is reduced. SIBO can also be a cause of Irritable Bowel Syndrome
