Publisher's Synopsis
Small intestinal bacterial overgrowth (SIBO) is a condition that occurs when an excessive number of bacteria colonize the small intestine. It can cause bloating, diarrhea, or constipation. Bacteria are essential to the digestive system, in the form of the gut microbiome. This is mostly present in the large intestine, but the small intestine does not contain many bacteria. Gastric secretions and the forward movement of food through the digestive system prevent too many bacteria from growing in the small intestine. However, if these functions do not work effectively, bacteria can multiply. The small intestine is not able to handle high numbers of bacteria. When a person eats, these bacteria begin to ferment the food. In some people, this causes symptoms. SIBO appears to be related to irritable bowel syndrome (IBS). People with IBS are more likely to have SIBO than the rest of the population. However, not everyone with an IBS diagnosis tests positive for SIBO. Small intestinal bacterial overgrowth (SIBO) is a condition in which excessive gut bacteria are present in the small intestine.The goal of treating SIBO is not to entirely eliminate gut bacteria, but rather restore a normal balance of it. Antibiotics, such as Xifaxan(rifaximin), are usually the cornerstone of SIBO treatment. SIBO is common in people with other gastrointestinal disorders such as Crohn's disease and irritable bowel syndrome (IBS). Both of these conditions can encourage bacterial overgrowth in the small intestine and make symptoms worse, so treating them is important.
