Procedure
Colonoscopy
A camera examination of the large bowel to investigate symptoms and screen for polyps and bowel cancer.
What is a colonoscopy?
A colonoscopy uses a thin, flexible tube with a camera to look at the lining of the colon (large bowel) and rectum. Small tissue samples (biopsies) can be taken and many polyps can be removed during the same procedure.
Why might it be recommended?
Common reasons include blood in the stool, a persistent change in bowel habit, unexplained anaemia or weight loss, inflammatory bowel disease follow-up, and colorectal cancer screening.
Your doctor will discuss whether a colonoscopy is appropriate for you.
Preparation
The bowel must be emptied beforehand using a prescribed preparation and a modified diet. Clear, written instructions are given at booking. Please tell the clinic about all medicines you take, especially blood thinners, diabetes medicines and iron tablets.
On the day
Sedation is usually offered for comfort. You will need someone to accompany you home and should not drive for the rest of the day.
