This study evaluates for esophageal reflux, blockages, inflammation, ulcers or abnormalities in formation of the esophagus and stomach.

Preparation for the Exam

1. Nothing to eat or drink (except medications with a small amount of water) on the following schedule, depending on the child's age:
   • 0 to 2 months: nothing by mouth two hours prior to exam
   • 3 to 11 months: nothing by mouth three hours prior to exam
   • 1 to 4 years: nothing by mouth four hours prior to exam
   • 5 to 18 years: nothing by mouth eight hours prior to exam
2. Bring a bottle if the child is bottle feeding or a sippy cup if he or she uses one.
3. If the upper GI is through a G-tube or J-tube, bring a feeding tube attachment. No tube feedings based on above schedule.

During the Exam
Parents are usually allowed to stay in the X-ray room during the test. In most cases, your child will be changed into a gown. A pediatric technologist will discuss the procedure with children who are old enough to communicate. Age-appropriate language will be used to explain the exam.

The child will lie on the X-ray table and will drink a liquid contrast dye called barium. The barium can be flavored with orange fruit punch to make it easier for your child to drink. Your child will be rolled into different positions while drinking the barium. Images are obtained of the esophagus and stomach as the barium passes through them. The exam usually lasts about 30 minutes.

After the Exam
Your child’s stool may appear to be whitish in color for 48 hours to a week due to the barium. Encourage your child to drink fluids after the exam to allow his stool to return to normal within a short time.
