What is the definition of Diverticulosis?

Diverticulosis occurs when small, bulging sacs or pouches form on the inner wall of the intestine. These sacs are called diverticula. Most often, these pouches form in the large intestine (colon). They may also occur in the in the jejunum in the small intestine, although this is less common.

What are the alternative names for Diverticulosis?

Diverticula - diverticulosis; Diverticular disease - diverticulosis; G.I. bleed - diverticulosis; Gastrointestinal hemorrhage - diverticulosis; Gastrointestinal bleed - diverticulosis; Jejunal diverticulosis

What are the causes for Diverticulosis?

Diverticulosis is less common in people age 40 and younger. It's more common in older adults. About half of Americans over age 60 have this condition. Most people will have it by age 80.

No one knows exactly what causes these pouches to form.

For many years, it was thought that eating a low-fiber diet may play a role. Not eating enough fiber can cause constipation (hard stools). Straining to pass stools (feces) increases the pressure in the colon or intestines. This may cause the pouches to form at weak spots in the colon wall. However, whether a low-fiber diet leads to this problem is not well proven.

Other possible risk factors that are also not well proven are lack of exercise and obesity.

Eating nuts, popcorn, or corn does not appear to lead to inflammation of these pouches (diverticulitis).

What are the symptoms for Diverticulosis?

Most people with diverticulosis have no symptoms.

When symptoms occur, they may include:

  • Pain and cramps in your stomach
  • Constipation (sometimes diarrhea)
  • Bloating or gas
  • Not feeling hungry and not eating

You may notice small amounts of blood in your stools or on toilet paper. Rarely, more severe bleeding may occur.

What are the current treatments for Diverticulosis?

Because most people have no symptoms, most of the time, no treatment is needed.

Your health care provider may recommend getting more fiber in your diet. A high-fiber diet has many health benefits. Most people don't get enough fiber. To help prevent constipation, you should:

  • Eat plenty of whole grains, beans, fruits, and vegetables. Limit processed foods.
  • Drink plenty of fluids.
  • Get regular exercise.
  • Talk with your provider about taking a fiber supplement.

You should avoid NSAIDs such as aspirin, ibuprofen (Motrin), and naproxen (Aleve). These medicines can make bleeding more likely.

For bleeding that does not stop or recurs:

  • Colonoscopy may be used to inject medicines or burn a certain area in the intestine to stop the bleeding.
  • Angiography may be used to infuse medicines or block off a blood vessel.

If bleeding does not stop or recurs many times, removal of a section of the colon may be needed.

What is the outlook (prognosis) for Diverticulosis?

Most people who have diverticulosis have no symptoms. Once these pouches have formed, you will have them for life.

Up to 25% of people with the condition will develop diverticulitis. This occurs when small pieces of stool become trapped in the pouches, causing infection or swelling.

What are the possible complications for Diverticulosis?

More serious problems that may develop include:

  • Abnormal connections that form between parts of the colon or between the colon and another part of the body (fistula)
  • Hole or tear in the colon (perforation)
  • Narrowed area in the colon (stricture)
  • Pockets filled with pus or infection (abscess)

When should I contact a medical professional for Diverticulosis?

Call your provider if symptoms of diverticulitis occur.
