How do I prepare for a colonoscopy?

A colonoscopy is a physical procedure which gives the surgeon detailed visibility of the large bowel. A colonoscope fitted with a minute camera is inserted through the rectum, the patient may request local or general anaesthetic for the procedure. 

You'll need to prepare your bowel with medication typically taken 24 hours beforehand, and by making dietary changes up to five days before the procedure. It's important you fully understand what's required of you well in advance to make sure the colonoscopy provides the most accurate results.
