Upper Gastrointestinal (UGI) Series

Risks

Barium does not move into the blood, so allergic reactions are very rare.

Some people gag while drinking the barium fluid. In rare cases, a person may choke and inhale (aspirate) some of the liquid into the lungs.

There is a small chance that the barium will block the intestine or leak into the belly through a perforated ulcer. A special type of contrast material (Gastrografin) can be used if you have a blockage or an ulcer.

There is always a small chance of damage to cells or tissue from being exposed to any radiation, even the low level of radioactive tracer used for this test.
