Colonoscopy

Colonoscopy is a painless medical examination used to look for any changes, such as irritated tissues, swelling, polyps, or cancer inside your large intestine (colon). It is the most effective test for detecting and evaluating gastrointestinal conditions such as inflammatory bowel disease (IBD), ulcerative colitis, Crohn's disease, diverticulitis, and colon cancer. The colonoscopy test usually takes 30 to 60 minutes.

What is a colonoscopy?

A colonoscopy is a diagnostic test that lets your doctor examine the inside of your large intestine, which includes your colon, rectum, and anus. Colonoscopy is a type of endoscopy, where a gastroenterologist uses an endoscope, a flexible tube that has a small camera and light at the tip.

An expert gently inserts it through your anus and moves it slowly through the colon. The camera transmits images from inside your large intestine that allow the doctor to check for swelling, ulcers, bleeding, polyps, or signs of cancer. During the procedure, the doctor may take tissue samples (biopsies) or remove any polyps found for further examination.

FAQs

A colonoscopy is usually not painful, as you are given light sedation to keep you relaxed and comfortable during the procedure.
