Diverticula are small pouches that form in the bowel lining, usually in the lower part of the colon. These pouches usually result from pressure on weak spots in the intestine, such as when one strains with constipation during a bowel movement. Straining from constipation is an example of this kind of pressure. The diverticula are usually harmless, but bacteria can build up if the pouches are blocked with waste. Diverticulitis occurs if the pouches break open and cause inflammation and infection.
