Diverticulosis: Symptoms & Signs

Medically Reviewed on 3/11/2020

Diverticulosis is a condition in which there are small outpouchings, or bulging sacs, protruding from the large intestine (colon). Diverticulosis is also known as diverticular disease. The colon wall becomes thicker with age, and diverticulosis is more common in older people.

Diverticulosis itself typically does not cause any symptoms or signs in many cases. When it does cause signs and symptoms, constipation and abdominal pain are the most common. Instead, symptoms can develop and are more common when the small sacs, or diverticula, become inflamed. This condition is known as diverticulitis. Signs and symptoms associated with diverticulitis can include
