SIBO stands for Small Intestine Bacterial Overgrowth. While bacteria in the digestive system are normal and necessary for the breakdown of foods and absorption of nutrients, the highest concentration is typically in the colon or large intestine, not the small intestine. When bacteria overpopulate the small intestine, the body cannot properly assimilate nutrients from food. This, in turn, can lead to the aggravation of existing chronic health conditions or other symptoms.
Excessive trapped gas in the gut leads to bloating. While digestion and processing of certain foods, especially those high in fiber, can cause bloating, SIBO also produces this painful symptom. Bacteria in the gut consume carbohydrates from the food we eat and process them in a way that produces gas and other by-products. The gas from the bacteria builds up and causes gas and bloating.
