What to Expect
Prior to Test
- As with all x-ray tests, make sure you let your doctor know if you are pregnant.
- Talk to your doctor about the medication you are taking. They may need to be adjusted before the test.
- Do not eat, drink, or smoke for at least 8 hours before the test.
- You may be given a medication called glucagon . This will slow down the activity of the stomach and small intestine.
- You may be asked to swallow baking soda crystals. These crystals will bubble and make gas in your stomach, allowing for x-rays that are more detailed.
- If the doctor wants to look at lower parts of your intestine, you may need to take a laxative the day before your exam. This will clean out your intestine.
