A colonoscopy is an investigation using a flexible telescope to look at the lining of the large bowel (colon).
A long tube (a colonoscope) is inserted at the anus and manoeuvred around as far as possible to the appendix (around 1.5 metres in length). In order to gain good views you will be asked to take a laxative (bowel prep) to clear out the bowel and you will also be asked to follow a restricted diet for two days before your procedure. You may also be asked to stop some medications.
