Upper Gastrointestinal (UGI) Series

The barium liquid is thick and chalky, and some people find it hard to swallow. A sweet flavor, like chocolate or strawberry, is used to make it easier to drink. Some people do not like it when the X-ray table tilts. You may find that pressure on your belly is uncomfortable. After the test, many people feel bloated and a little nauseated.

For 1 to 3 days after the test, your stool (feces) will look white from the barium. Call your doctor if you are not able to have a bowel movement in 2 to 3 days after the test. If the barium stays in your intestine, it can harden and cause a blockage. If you become constipated, you may need to use a laxative to pass a stool.
