The procedure to diagnose and treat, when possible, certain diseases of the lower gastrointestinal (GI) tract, which includes the rectum and colon.
A colonoscopy may be used to screen for colon cancer and evaluate many problems, including: • Abdominal pain • Anemia (low red blood cells) • Blood in the stool • Change in bowel habits • Unexplained weight loss Colonoscopy is often used to treat certain conditions:
• Bleeding from diverticula or other lesions can be treated by injecting medicine around them or by applying heat to cauterize -- or seal -- them. • Polyps, some of which may be cancerous, can be removed using a lasso-like device through the colonoscope. • Narrowed areas or strictures can often be dilated using a balloon.
