Diverticula

Diverticulosis occurs when small bulging sacs or pouches, called diverticula, form on the inner wall of the intestine. Most often, diverticula form in the large intestine (colon), but they may also occur in the in the jejunum in the small intestine. In most cases, diverticula cause no symptoms. In a small percentage of patients, diverticula can cause problems if they become inflamed or if they bleed.
