FODMAP

FODMAPs are a group of sugars that are not completely digested or absorbed in our intestines. When FODMAPs reach the small intestine, they move slowly, attracting water. When they pass into the large intestine, FODMAPs are fermented by gut bacteria, producing gas as a result. The extra gas and water cause the intestinal wall to stretch and expand. Because people with IBS have a highly sensitive gut, ‘stretching’ the intestinal wall causes exaggerated sensations of pain and discomfort.
