What happens during a sigmoidoscopy?

You’ll be asked to lie on your left-hand side with your legs bent so your doctor can gently examine your rectum by inserting a finger. They’ll then carefully insert the sigmoidoscope into your rectum, using a lubricating jelly to make this as comfortable as possible.

Air will be pumped through the sigmoidoscope into your lower bowel so it's easier for your doctor to see your bowel wall. This may cause stomach cramps or give you the feeling of needing to go to the toilet or pass wind.

Your doctor will then examine images from inside your bowel via a camera at the end of the sigmoidoscope. If necessary, your doctor can take a biopsy or remove any polyps you have, using special instruments that are passed inside the sigmoidoscope.

Carrying out sigmoidoscopy exams

A flexible sigmoidoscopy usually takes between 10 and 20 minutes but you’ll probably be in hospital for one to two hours in total. The procedure may be uncomfortable, but shouldn't be painful.
