You will be given instructions about this by your hospital. Just before the test you may be given a mild sedative to help you feel more relaxed. As the tube is made up of flexible fibres, it can easily pass around curves and the whole length of the large bowel can be examined. A light on the inside of the tube helps the doctor to see any abnormal areas or swelling. A colonoscopy can be uncomfortable but the sedative will help you feel more relaxed.
Most people are ready to go home a couple of hours after their test.
It is a good idea to arrange for someone to collect you from the hospital as you shouldn't drive for several hours after a sedative. All rights reserved. Readers are strongly advised to discuss the information with their doctor.
