diverticulosis

diverticulosis The condition of having diverticula, small outpouchings from the large intestine (colon). Diverticulosis can occur anywhere in the colon but is most typical in the sigmoid colon, the Sshaped segment of the colon located in the lowerleft part of the abdomen. The incidence of diverticulosis increases with age. As a person ages, the walls of the colon weaken, and this weakening permits the formation of diverticula. By age 80, most people have diverticulosis. Diverticulosis sets the stage for inflammation and infection of the diverticula (diverticulitis). A diet that is high in fiber keeps the bowels moving, keeps the pressure in the colon within normal limits, and slows or stops the formation of diverticula. See also diverticulitis.
