When might you need a colonoscopy if you think you have irritable bowel syndrome?

ANSWER

Your doctor might order a colonoscopy, an exam that looks for polyps in your large intestine. Another option may be a test called a flexible sigmoidoscopy. During both procedures, your doctor puts a narrow, flexible tube with a camera into your rectum. He or she moves it into your body to examine part or all of the large intestine.

During the colonoscopy, your doctor may collect small sections of tissue from the large intestine and examine them under a microscope. It won't show if you have irritable bowel syndrome, but you may learn if you've got other conditions like colitis or inflammatory bowel disease.
