Diverticular Disease

(Also Called 'Diverticulosis', 'Esophageal Diverticulum')

Diverticular disease consists of diverticulosis and diverticulitis. Diverticulosis is the formation of numerous tiny pockets, or diverticula, in the lining of the bowel. Diverticula, which can range from pea-size to much larger, are formed by increased pressure on weakened spots of the intestinal walls by gas, waste, or liquid. Diverticula can form while straining during a bowel movement, such as with constipation. They are most common in the lower portion of the large intestine (called the sigmoid colon).


Complications can occur in about 20 percent of people with diverticulosis. One of these complications is rectal bleeding, called diverticular bleeding, and the other is diverticulitis.


Diverticular bleeding occurs with chronic injury to the small blood vessels that are adjacent to the diverticula. Diverticulitis occurs when there is inflammation and infection in one or more diverticula. This usually happens when outpouchings become blocked with waste, allowing bacteria to build up, causing infection.


Diverticulosis is very common in Western populations and occurs in 10 percent of people over age 40 and in 50 percent of people over age 60. The occurrence of diverticulosis increases with age, and it affects almost everyone over age 80.


What are the symptoms of diverticulosis?

Usually diverticulosis does not cause any troublesome symptoms. Some people may feel tenderness over the affected area or abdominal cramps.


How is diverticulosis diagnosed?

Because most people with diverticulosis do not have any symptoms, it is usually found through tests ordered for an unrelated reason.


How is diverticulosis treated?

People who have diverticulosis without symptoms or complications do not need treatment, yet it is important to adopt a high-fiber diet.

Laxatives should not be used to treat diverticulosis, and enemas should also be avoided or used infrequently.


How can diverticulosis be prevented?

Good bowel hygiene is most important to prevent diverticular disease or reduce the complications from it. This means having regular bowel movements and avoiding constipation and straining. Eating appropriate amounts of the right types of fiber are important to maintain good bowel hygiene. Drinking plenty of water and exercising regularly are also important.


The American Dietetic Association recommends 20 to 35 grams of fiber a day. Every person, regardless of the presence of diverticula, should try to consume this much fiber every day. Fiber is the indigestible part of plant foods. High-fiber foods include whole grain breads, cereals and crackers; berries; fruit; vegetables, such as broccoli, cabbage, spinach, carrots, asparagus, squash, and beans; brown rice; bran products; and cooked dried peas and beans, among other foods.


A high-fiber diet helps prevent constipation and provides a number of other health benefits, including lower blood pressure, reduced blood cholesterol, improved blood sugar, and reduced risk of developing certain intestinal disorders.


Drinking eight 8-ounce glasses of water a day, monitoring changes in bowel movements (from constipation to diarrhea), and getting enough rest and sleep are other ways to

prevent diverticular disease.


What Are the Complications of Diverticulitis?

Serious complications can occur as a result of diverticulitis. Most of them are the result of the development of a tear or perforation of the intestinal wall. If this occurs, intestinal waste material can leak out of the intestines and into the surrounding abdominal cavity causing the following problems:

  • Peritonitis (a painful infection of the abdominal cavity)
  • Abscesses ("walled off" infections in the abdomen)
  • Obstruction (blockages of the intestine)
  • Bleeding
