A colonoscopy procedure uses a flexible tube called a colonoscope, which is inserted into your anus through the rectum. It is flexible and is able to move around curves, allowing it to travel the length of your colon.
At the end of the tube is a tiny video camera that allows the doctor to view the inside of the entire colon, and diagnose any abnormalities.

If needed, abnormal tissue, polyps or tissue samples (biopsies) may also be taken during a colonoscopy.
The procedure requires preparation, including a clear liquid diet the day before and a series of strong laxatives to clear your intestines prior to the procedure.

The procedure itself is done with light sedation, and takes about 20-30 minutes. Most patients can normally go home about two hours later (once the sedation has worn off) with someone to stay with you overnight. Most patients can return to normal activities the next day, however you cannot drive for 24 hours.

Your GP may refer you for a colonoscopy if you are experiencing bowel problems or symptoms, if a bowel cancer screening test has returned a positive result, or due to previous colonoscopy results or family history.

While colonoscopies do have some risks, it is work considering that the risks that can arise from not having one are relatively, much greater.

If during your test, the doctor removes a polyp or tissue, your chances of complications may increase slightly.

Side effects of a colonoscopy can include;

• a small amount of blood coming from your rectum or in your first bowel movement
• temporary abdominal or light cramping pain
• feeling bloated or gassy. This can sometimes occur as a result of air being added to your colon during the procedure.
• nausea, mainly as a result of anaesthesia.
• rectal irritation from the bowel prep or the procedure itself.

Your surgeon will discuss all possible risks and side effects with you in your pre-procedure consultation.
