You should see your health care provider if this happens. Diverticula are best seen with a special intestinal x-ray called a barium enema. In fact, diverticulosis may be discovered when you have this test for some other medical problem. Barium is put into your rectum and colon. The barium then shows the outline of the large intestine on the x-ray.
Flexible sigmoidoscopy is another procedure that can find diverticula.
The doctor inserts a scope into your rectum. The scope is a thin, flexible, lighted tube. The doctor can then look inside your large intestine. Most importantly, you need to have more fiber in your diet. Also eat more fruits and vegetables.
