Diverticulitis is effectively treated by preventing constipation, according to WebMD. This is best accomplished by eating high-fiber foods, drinking plenty of fluids, exercising daily, taking a fiber supplement and scheduling a daily bowel movement.
Diverticulitis begins with a condition called diverticulosis, which occurs when pouches are formed within the wall of the bowel. While this typically occurs within the colon or large intestine, it may occur within the small intestine as well. When one or more of these pouches becomes inflamed, the condition known as diverticulitis results. When measures are taken to prevent constipation, the chances of formation of new pouches are reduced, as is the risk of diverticulitis developing.
