Upper GI (Gastrointestinal) Series

How do you 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 doctor if you have serious bowel movement problems after the test.

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

• Your next appointment is:__________________
