Diverticula are small, bulging sacs or pouches that form on the inner wall of the intestine. Diverticulitis occurs when these pouches become inflamed or infected. Most often, these pouches are in the lower part of the large intestine (colon).


In most patients with diverticulosis, the diverticula do not cause any problems or symptoms. In some cases, a small, hard piece of stool is trapped in the opening of the diverticula, which then become inflamed. When this occurs, the condition is called diverticulitis. A small tear may develop in the lining of the intestine inside the diverticula, which can lead to an infection at the site and sometimes death of the segment of colon containing the diverticula.


Diverticulosis occurs when small bulging sacs or pouches, called diverticula, form on the inner wall of the intestine. Most often, diverticula form in the large intestine (colon), but they may also occur in the in the jejunum in the small intestine. In most cases, diverticula cause no symptoms. In a small percentage of patients, diverticula can cause problems if they become inflamed or if they bleed.


There are 3 basic tests for colon cancer; a stool test (to check for blood), sigmoidoscopy (inspection of the lower colon), and colonoscopy (inspection of the entire colon). All 3 are effective in catching cancers in the early stages, when treatment is most beneficial.

Digestive system

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Colon diverticula - series

The colon, or large intestine, is a muscular tube that begins at the end of the small intestine and runs to the rectum. The colon absorbs water from liquid stool that is delivered to it from the small intestine.
