What is an Upper GI Test?
An upper gastrointestinal (GI) test uses X-rays to take pictures of the stomach and small bowel. The test helps the doctor see how well these organs are working.
Before the Test
Before you come to the hospital, explain to your child what will happen. For young children, use simple words and explain only right before the test.
You should receive specific eating and drinking instructions for your child before the test. If your child is taking medicines ordered by a doctor, confirm that you should give them at the normally scheduled times.
During the Test
During the test, your child will drink a special liquid called barium. Barium is a milky-white liquid that is usually strawberry or fruit-flavored. After they drink the liquid, a doctor (radiologist) or X-ray technologist will take X-rays of your child's belly.
Nothing will hurt your child during the test, but they will need to lie still on the X-ray table. If your child is unable to lie still, staff may help your child with holding still.
Often, more X-ray pictures are taken after waiting for the barium to pass through the stomach and intestines. The test may last two hours or more.
It is possible that during the procedure your child may experience some discomfort. Tell the doctor, nurse or technologist if pain occurs.
After the Test
Your child may return to normal daily activities. Results of the test will be sent to your child's doctor.
After the upper GI test, it is helpful for your child to drink plenty of liquids to help them pass the barium out of their intestine. Give your child liquids like juices, water, and Kool-Aid or fruit punch. It is possible that your child's stool may appear whitish in color for 24-48 hours after the test because of the barium that they swallowed.
