How Does a Colonoscopy Work?

During a colonoscopy, you lie on your side with knees drawn to your chest. You'll receive IV medication to stay comfortable. A thin, camera-equipped tube is inserted through the anus to view and assess your colon and rectum, removing polyps and taking biopsies as needed. The procedure typically lasts 15-30 minutes and is usually painless.

What Happens During Your Procedure?

Visualisation & Biopsies

The colonoscope inflates the colon for better visualisation. Biopsies may be taken for further analysis. AI software might assist.

Recovery & Aftercare
