Diverticula

Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are most often found in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems.

Causes

The exact cause of diverticula is unknown, but they seem to be a byproduct of aging, diet, and genetics. Some researchers believe that a low-fiber diet can lead to diverticula. The theory is that fiber prevents constipation and makes the waste softer and easier to pass. Without fiber, the colon has to work harder than normal to push the waste out. Over time, this pressure can cause pouches to form in weak spots along the colon.

Symptoms

Most people with diverticula don't have any symptoms. However, some people may experience mild cramps, bloating, and constipation. Other people may have more severe symptoms, such as bright red blood in the stool or abdominal pain.

Diagnosis

Doctors often find diverticula during an colonoscopy or sigmoidoscopy. If you have symptoms, your doctor may use other tests to rule out other conditions.

Treatment

Treatment for diverticula depends on the severity of your symptoms. If you have no symptoms, your doctor may suggest a high-fiber diet to help prevent more diverticula. If you have symptoms, your doctor may suggest over-the-counter pain relievers and a liquid diet until your symptoms improve. In severe cases, you may need surgery.

Prevention

Eating a high-fiber diet can help prevent diverticula. Exercise also seems to play a role in preventing diverticula.
