Understanding New and Severe Abdominal Pain

When diarrhea is not a prominent symptom, fever and pain in the lower abdomen can be signs of the serious infection, "diverticulitis." You should have your symptoms evaluated by a doctor right away.

Changes in the colon that occur with age (particularly if you have a history of constipation) can predispose you to infection. Many adults form "diverticuli" as they age, which are hollow tubular bulges that branch from the colon lining. These pockets can accumulate bacteria and can cause symptoms much like appendicitis. Between episodes of infection, diverticuli can be asymptomatic, or they may cause pain or brisk bleeding.
