A mild sedative helps you to relax during the test and a local anaesthetic will be sprayed onto your throat to prevent any discomfort as the tube is passed. This test is called a colonoscopy. The bowel must be empty for this test so a careful diet must be followed beforehand. A bowel wash-out is done just before the test. A mild sedative helps you to relax as the endoscope is passed along your large bowel.
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 the sedative can make you feel very sleepy. It is best not to drive for several hours afterwards. If tests show that your lungs have been affected you may have lung function tests to check the capacity and efficiency of your lungs. By blowing into a machine a series of measurements can be taken to show how well your lungs are working. All rights reserved.
