Inflammation of diverticula (see DIVERTICULUM) in the large intestine. It is characterised by pain in the left lower part of the abdomen. The onset is often sudden, with fever and constipation. It may, or may not, be preceded by DIVERTICULOSIS. Treatment consists of rest, no solid food but ample fluid, and the antibiotic TETRACYCLINE. Complications are unusual but include ABSCESS formation, perforation of the colon, and severe bleeding.
