Diverticulosis is a condition characterized by the formation of small pouches, known as diverticula, in the walls of the colon. These pouches develop due to increased pressure in the colon, often associated with a low-fiber diet. While diverticulosis itself typically does not cause symptoms, it can lead to complications such as diverticulitis, where the pouches become inflamed or infected. Regular dietary fiber intake is recommended to help manage and prevent the condition.
