Diverticulitis

Condition Basics

What is diverticulitis?

Diverticulitis is a condition that happens when pouches (diverticula, Opens dialog) form in the wall of the colon, Opens dialog and then become inflamed or infected. This can cause tenderness, cramps, or pain in the belly. Not everyone who has these pouches gets diverticulitis. Mild attacks may heal on their own.

What causes it?

Doctors aren't sure what causes diverticulitis. Bacteria grow in pouches (diverticula, Opens dialog) that sometimes form in the wall of the colon. These bacteria can lead to inflammation or infection. Doctors think diverticula form when high pressure inside the colon pushes against weak spots in the colon wall.

What are the symptoms?

Belly pain, often in the lower left side, is the most common symptom of diverticulitis. The pain is sometimes worse when you move. Other symptoms include fever, chills, bloating, and gas. You may also have diarrhea or constipation. Symptoms can last from a few hours to several days, or longer if not treated.

How is it diagnosed?

To diagnose diverticulitis, your doctor will ask questions about your symptoms and examine you. You may have tests to see if you have an infection or other problems. The tests may include blood tests or a digital rectal exam. They may also include CT scans, ultrasound, or X-rays of your belly, or other tests.

How is diverticulitis treated?

Treatment for mild symptoms of diverticulitis starts with antibiotics, pain medicines, and diet changes. You can try home treatment, such as a heating pad, for pain. To treat serious symptoms, you may need a hospital stay or surgery.
