Question:  What are the treatments for Diverticular Disease ?
Answer: A health care provider may treat the symptoms of diverticulosis with a high-fiber diet or fiber supplements, medications, and possibly probiotics. Treatment for diverticular disease varies, depending on whether a person has diverticulitis or diverticular bleeding.
                
Diverticulosis
                
High-fiber diet. Studies have shown that a high-fiber diet can help prevent diverticular disease in people who already have diverticulosis.2 A health care provider may recommend a slow increase in dietary fiber to minimize gas and abdominal discomfort. For more information about fiber-rich foods, see Eating, Diet, and Nutrition.
                
Fiber supplements. A health care provider may recommend taking a fiber product such as methylcellulose (Citrucel) or psyllium (Metamucil) one to three times a day. These products are available as powders, pills, or wafers and provide 0.5 to 3.5 grams of fiber per dose. Fiber products should be taken with at least 8 ounces of water.
                
Medications. A number of studies suggest the medication mesalazine (Asacol), given either continuously or in cycles, may be effective at reducing abdominal pain and GI symptoms of diverticulosis. Research has also shown that combining mesalazine with the antibiotic rifaximin (Xifaxan) can be significantly more effective than using rifaximin alone to improve a persons symptoms and maintain periods of remission, which means being free of symptoms.4
                
Probiotics. Although more research is needed, probiotics may help treat the symptoms of diverticulosis, prevent the onset of diverticulitis, and reduce the chance of recurrent symptoms. Probiotics are live bacteria, like those normally found in the GI tract. Probiotics can be found in dietary supplementsin capsules, tablets, and powdersand in some foods, such as yogurt.
                
To help ensure coordinated and safe care, people should discuss their use of complementary and alternative medical practices, including their use of dietary supplements and probiotics, with their health care provider. Read more at www.nccam.nih.gov/health/probiotics.

Diverticular Bleeding
                
Diverticular bleeding is rare. Bleeding can be severe; however, it may stop by itself and not require treatment. A person who has bleeding from the rectumeven a small amountshould see a health care provider right away.
                
To treat the bleeding, a colonoscopy may be performed to identify the location of and stop the bleeding. A CT scan or angiogram also may be used to identify the site of the bleeding. A traditional angiogram is a special kind of x ray in which a thin, flexible tube called a catheter is threaded through a large artery, often from the groin, to the area of bleeding. Contrast medium is injected through the catheter so the artery shows up more clearly on the x ray. The procedure is performed in a hospital or an outpatient center by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed, though a sedative may be given to lessen anxiety during the procedure.
                
If the bleeding does not stop, abdominal surgery with a colon resection may be necessary. In a colon resection, the surgeon removes the affected part of the colon and joins the remaining ends of the colon together; general anesthesia is used. A blood transfusion may be needed if the person has lost a significant amount of blood.
                
Diverticulitis
                
Diverticulitis with mild symptoms and no complications usually requires a person to rest, take oral antibiotics, and be on a liquid diet for a period of time. If symptoms ease after a few days, the health care provider will recommend gradually adding solid foods back into the diet.
                
Severe cases of diverticulitis with acute pain and complications will likely require a hospital stay. Most cases of severe diverticulitis are treated with intravenous (IV) antibiotics and a few days without food or drink to help the colon rest. If the period without food or drink is longer, the person may be given parenteral nutritiona method of providing an IV liquid food mixture through a special tube in the chest. The mixture contains proteins, carbohydrates, fats, vitamins, and minerals.
