A colonoscopy is a flexible scope that is inserted through the rectum to diagnose and treat problems with the lower GI tract (rectum, colon). It is commonly used to further work up patients with:
 
* Bright red blood per rectum (BRBPR)
* Melena
* Unexplained constipation/diarrhea
* Routine follow-up for patients with known polyps, IBD, other chronic bowel disease
* Colon cancer screening (in US, every 10 years after age 45)
