Definition of Diverticulitis
Diverticulitis is swelling (inflammation) of an abnormal pouch (diverticulum) in the intestinal wall. These pouches are usually found in the large intestine (colon). The presence of the pouches themselves is called diverticulosis.
Causes, incidence, and risk factors
Small, protruding sacs of the inner lining of the intestine (diverticulosis) can develop in any part of the intestine. They are most common in the colon, especially the sigmoid colon, the lowest part of the colon.
Signs and tests
Tests showing diverticulitis may include:
Treatment
Acute diverticulitis is treated with antibiotics.
Expectations (prognosis)
Usually, this is a mild condition that responds well to treatment.
