What is it?
Small, painless pouches, called diverticula, can develop in the walls of the digestive tract. Diverticulosis is a condition that is created when numerous pouches form in the colon. It is not known what causes these pouches to develop. It is believed to be caused, in part, by lack of dietary fiber, which can lead to constipation and pressure on the digestive tract. This pressure, over time, can cause the tract walls to become weak, which causes diverticula to develop.
