Upper GI (Gastrointestinal) Series

How do I get ready for an upper GI series?

• Follow any directions you are given for not eating or drinking before your test.

• Be sure to mention the medicines you take, and ask if it’s OK to take them before your test.

• Don't smoke the morning of the test.

• The test usually takes about 30 minutes. Allow extra time to check in.

What to tell the technologist

Tell the technologist if:

• You have any allergies

• You ate or drank within the last 8 hours

• You’re pregnant or think you may be

• You’ve had any previous surgery

• You take any medicines

What happens during an upper GI series? 

• You will drink a liquid (barium) that improves X-ray images.

• You also may swallow "fizzies." This is a substance that makes air build up in your stomach. Don’t burp, even if you feel you have to.

• You may need to stand. You will also lie in different positions or have your exam table tilted in various directions.

• You will be asked to hold your breath for a short time during the X-ray.

What happens after an upper GI series? 

• Your stool may appear white or lighter than normal for 2 to 3 days.

• You may have constipation caused by the barium. You can relieve this by taking an over-the-counter laxative or stool softener and drinking lots of fluids for several days after the exam. Talk with your healthcare provider if you have serious bowel movement problems after the test.

• Your healthcare provider will discuss the test results with you during a follow-up appointment or over the phone.

• Your next appointment is:__________________
