In most people, diverticulosis never presents problems or symptoms. However, about 20 percent of people experience side effects of this disease when the diverticula become inflamed. This condition, called diverticulitis, can result in rectal bleeding, abdominal infections and in severe cases, ruptures of the bowel . Aside from aging, the most obvious link to diverticular disease is a low fiber diet. On the other hand, the disease is rare in populations whose diets consist of high fiber fruits and vegetables.
Dietary fiber makes stools soft and prevents constipation.
With constipation, muscles strain to move the firm stool, causing increased pressure in the colon and bulging of weak spots in the colon, or diverticula. In addition to reducing the risk of diverticulosis, fiber may also have some protective effects against high cholesterol and certain types of cancer. The American Dietetic Association recommends 20 to 35 grams of fiber each day. In addition to increasing the fiber in your diet, fiber supplements which are mixed with water may also be recommended. It is important to note that excessive fiber supplementation without adequate water intake can cause bowel blockage.
