You likely had a CT scan or other tests that helped your health care provider diagnose your symptoms and check your colon. This will help tell if there are complications from your diverticulitis. You may have received fluids and medicines that fight infections through an intravenous (IV) tube in your vein. You were probably on a special diet to help your colon rest and heal.

If your diverticulitis was very bad, or a repeat of a prior episode, you may need surgery.

Your provider may also recommend that you have further tests to look at your colon (large intestine) such as colonoscopy. It is important to follow up with these tests.

Your pain and other symptoms should go away after a few days of treatment. If they do not get better, or if they get worse, you should contact the provider.

Once these pouches have formed, you have them for life. If you make a few simple changes in your lifestyle, you may not have diverticulitis again.

Your provider may have given you antibiotics to treat any infection. Take them as you were told to. Make sure you finish the whole prescription. Contact your provider if you have any side effects.

Do not put off having a bowel movement. This can lead to a firmer stool, which will make you need to use more force to pass it.

Eat a healthy, well-balanced diet. Do not smoke. Exercise regularly. Avoid constipation.

Fiber supplements such as psyllium may decrease your risk of diverticulitis.

If you are taking NSAIDs (such as naproxen or ibuprofen) ask your provider if you can stop them. NSAIDs can increase the risk of diverticulitis.

When you first go home or after an attack, your provider may ask you to drink liquids only at first, then slowly increase your diet. In the beginning, you may need to avoid whole-grain foods, fruits, and vegetables. This will help your colon rest.

After you are better, your provider will suggest that you add more fiber to your diet and avoid certain foods. Eating more fiber may help prevent future attacks. If you have bloating or gas, cut down the amount of fiber you eat for a few days.

High fiber foods include:

• Fruits, such as tangerines, prunes, apples, bananas, peaches, and pears
• Tender cooked vegetables, such as asparagus, beets, mushrooms, turnips, pumpkin, broccoli, artichokes, lima beans, squash, carrots, and sweet potatoes
• Lettuce and peeled potatoes
• Vegetable juices
• High-fiber cereals (such as shredded wheat) and muffins
• Hot cereals, such as oatmeal, farina, and cream of wheat
• Whole-grain breads (whole wheat or whole rye)
• Unlike old recommendations, you do not need to avoid corn, nuts, or seeds if you have diverticulosis or diverticulitis.

Contact your provider if you have:

• Blood in your stools
• Fever above 100.4°F (38°C) that does not go away
• Nausea, vomiting, or chills
• Sudden belly or back pain, or pain that gets worse or is very severe
• Ongoing diarrhea
