Diverticulitis tends to occur in people
who eat low-fiber diets.
It is difficult 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.
Generally, diverticulosis becomes more likely with age. It occurs in fewer than
10% of people under age 40. Of people over age 80, between 50% and 66% have the
condition.1
About 20% of the people who
have been diagnosed with diverticulosis develop diverticulitis, which occurs
when the pouches along the large intestine become inflamed or infected. Men and
women are affected almost equally.2
