You will be asked not to eat or drink anything for at least four hours before the test. Your stomach and duodenum need to be empty so that your doctor can get as clear a picture as possible.
If you are diabetic, you will get some special instructions to follow.
If you take regular medication, take your tablets as normal (with a small amount of water, if you need it).
The hospital will send you full details with your appointment letter. If in doubt, please ask.
If you can, leave any jewellery or metal objects at home, because you can’t wear them during the test. It is better not to bring them with you.
