Test Preparation
Upper GI

Upper gastrointestinal tract radiography, also called an upper GI, is an x-ray examination of the esophagus, stomach and first part of the small intestine (also known as the duodenum). Images are produced using a special form of x-ray called fluoroscopy and an orally ingested contrast material such as barium.

Before the Test: You must have nothing to eat or drink after midnight the night before your appointment. Water, gum or candy are not allowed. Please inform the receptionist if you are diabetic when booking the appointment. If you have anything in your stomach, the appointment will be rebooked.

During the Test: You will be asked to change into a gown. The radiologist will ask you to swallow some gas crystals to distend the stomach.  You will then drink some barium in order to see your esophagus, stomach and first part of the small bowel. . Barium is a contrast media which is dense as your bones. The radiologist will ask you to turn on the x-ray table as to coat the lining of the stomach with barium in order to visualize it in greater detail.  A series of picture will then be taken.

After the Test: Once the test is completed, you are able to return to your normal activities. It is recommended to drink lots of water for the next day to flush out the barium as the barium tends to constipate.

What to Bring: To avoid delays on the day of your test, ensure that you bring your health card and your requisition.
