Diverticular Disease

Diverticular disease consists of diverticulosis and diverticulitis. Diverticulosis is the formation of numerous tiny pockets, or diverticula, in the lining of the bowel. Diverticula, which can range from pea-size to much larger, are formed by increased pressure on weakened spots of the intestinal walls by gas, waste, or liquid. Diverticula can form while straining during a bowel movement, such as with constipation. They are most common in the portion of the large intestine called the sigmoid colon.
Complications can occur in people with diverticulosis. Diverticulosis is very common and the occurrence of diverticulosis increases with age.

One of these complications is rectal bleeding, called diverticular bleeding, and the other is diverticulitis. Diverticular bleeding occurs with chronic injury to the small blood vessels that are adjacent to the diverticula.

Diverticulitis occurs when there is inflammation and infection in one or more diverticula. This usually happens when outpouchings become blocked with waste, allowing bacteria to build up, causing infection.
