Diverticulosis is a condition characterized by the formation of small pouches, called diverticula, in the walls of the colon. These pouches develop when weak spots in the intestinal wall bulge out, often due to increased pressure from constipation or a low-fiber diet. Many people with diverticulosis experience no symptoms and may not even know they have it. In some cases, diverticulosis can lead to complications, such as diverticulitis, which occurs when the pouches become inflamed or infected. Symptoms of diverticulitis may include abdominal pain, fever, and changes in bowel habits. Maintaining a high-fiber diet can help prevent the development of diverticulosis and its complications.
