Signs and tests:

Tests usually reveal no abnormalities.
Not all patients require endoscopy, especially if symptoms begin early in life and have been stable. Patients who have irritable bowel symptoms beginning later in life usually require endoscopy.
Patients over age 50 should be screened for colon cancer.
Younger patients with persistent diarrhea may require endoscopy to look for inflammatory bowel disease. Irritable bowel syndrome, by contrast, is not an inflammatory condition, but the symptoms may be very similar to those of inflammatory bowel disease.
