Who Is Affected by Diverticulitis

It is hard to determine the exact incidence of diverticulosis (the formation of pouches in the wall of the large intestine), because most people who have colon pouches do not have symptoms. In general, diverticulosis becomes more likely with age.

About 20 out of 100 people who have been diagnosed with diverticulosis develop diverticulitis. This occurs when the pouches along the large intestine become inflamed or infected. Men and women are affected almost equally.footnote 1
