Why Does Diverticulosis Cause Constipation?

Symptoms

Diverticulosis is a condition in which small pouches in the lining of the colon bulge out through weak spots called diverticulum. According to the National Digestive Diseases Information Clearinghouse, approximately 10 percent of people over age 40 suffer from diverticulosis. Symptoms include lower abdominal pain, bloating and constipation. The involvement of constipation in relation to this condition may be viewed as both a symptom and contributing factor.

Cause

Chronic constipation is a contributor to the formation of diverticula because straining to defecate puts pressure on the intestinal walls. The cause of diverticulosis remains uncertain, but a low-fiber diet may be a contributing factor. According to the Medical College of Wisconsin, constipation exerts increased pressure on the colon, which causes weak spots in the colon to bulge and become diverticula. As more strain is put on the colon, the pouches are pushed out through the weak spots causing a steady progression of diverticula. Increasing dietary fiber can help stop or slow that progression.

Diet

People who suffer from diverticulosis should consume a diet rich in fiber to combat constipation. A high-fiber diet can decrease straining by softening the stool. Fiber should be added to the diet slowly to avoid any unnecessary stomach upset or imbalance. Foods that are high in fiber include fruits, vegetables, beans, whole grains, rice and oatmeal. It is relatively simple to increase your fiber intake simply by incorporating cereal or oatmeal into the breakfast routine, eating vegetables with lunch and dinner as well as eating fruit for snacks. Doing so will help soften the consistency of stools, thereby alleviating the discomfort of diverticulosis.
