It should take 30 to 45 minutes to have your colonoscopy.
But you might be at the hospital for around 2 hours from getting there to going home.
|What happens||What it might feel like|
|A thin, flexible tube with a small camera inside goes into your bottom||You may feel the camera go in, but it should not hurt|
|Air is pumped in to open up your bowels||You may feel a bit bloated or like you need the toilet|
|The tube goes through all of your large bowel||You may have some stomach cramps|
|Any growths (polyps) in your bowels will be removed or a sample of cells taken||You will not feel anything if this happens|
You’ll usually be told if any growths (polyps) have been removed.
You'll then be moved to the recovery room. The nurses will monitor you until you're ready go home.
