Understanding Diverticulosis and Diverticulitis

Front view of colon with diverticula pouches in lower part.The colon (large intestine) is the last part of the digestive tract. It absorbs water from stool and changes it from a liquid to a solid. In certain cases, small pouches called diverticula can form in the colon wall. This condition is called diverticulosis. The pouches can become infected. If this happens, it becomes a more serious problem called diverticulitis. These problems can be painful. But they can be managed.

Managing your condition

Diet changes or medicines may be prescribed. 

If you have diverticulosis

Recommendations include:

  • Diet changes are often enough to control symptoms. The main changes are adding fiber (roughage) and drinking more water. Fiber absorbs water as it travels through your colon. This helps your stool stay soft and move smoothly. Water helps this process.

  • If needed, you may be told to take over-the-counter stool softeners.

  • To help relieve pain, antispasmodic medicines may be prescribed.

  • Watch for changes in your bowel movements. Tell the healthcare provider if you notice any changes.

  • Begin an exercise program. Ask your healthcare provider how to get started.

  • Get plenty of rest and sleep. 

If you have diverticulitis

Treatment depends on how bad your symptoms are.

  • For mild symptoms. You may be put on a liquid diet for a short time. Antibiotics are usually prescribed. If these two steps relieve your symptoms, you may then be prescribed a high-fiber diet. If you still have symptoms, your healthcare provider will discuss more treatment choices with you.

  • For severe symptoms. You may need to be admitted to the hospital. There, you can be given IV antibiotics and fluids. You will also be put on a low-fiber or liquid diet. Although not common, surgery is needed in some people with severe symptoms.
