Diverticulosis is a condition in which there are small pouches or pockets in the wall or lining of any portion of the digestive tract. These pockets occur when the inner layer of the digestive tract pushes through weak spots in the outer layer. high-fat, low-fiber diet is the main culprit in diverticulosis, or the formation and periodic inflammation of out-pouchings in the intestinal wall. Genetics and low physical activity levels may also play a role. Mild diverticulitis is treated with antibiotics. Surgery is needed if problems develop. A high fiber diet, exercise and drinking lots of water can help prevent.
