Barium Swallow - Upper GI and Small Bowel Series

What is involved in preparation for the test?

The individual is asked to refrain from drinking or eating for 8 hours before the test. If there is any concern over possible pregnancy, a pregnancy test should be done before the barium swallow. During the process, people must remove all jewelry and metal objects since these may interfere with the X-ray pictures. The healthcare provider will tell the individual if any other preparations are required.
