IBS-D shares most symptoms — including abdominal pain, bloating, and gas — with the other IBS subtypes, but in IBS-D, diarrhea is the predominant bowel habit. People with IBS-D also report more abdominal pain compared to the other subtypes.[1]
Symptoms often subside after a bowel movement, but will sometimes worsen after certain triggers such as caffeine, psychological stress, and foods high in certain fermentable carbohydrates (e.g., beans and wheat products; see Low-Fodmap Diet).[2]
