Home > Swallowing Study
A swallowing study is a test that shows what your throat and esophagus do while you swallow. The test uses X-rays in real time (fluoroscopy) and records what happens when you swallow. While you swallow, the doctor and speech pathologist watch a video screen.
For a swallowing study, you will swallow liquid mixed with a substance called barium. Or you might swallow solid foods coated with barium.
The barium shows the movements of your throat and esophagus on the X-ray while you swallow.
The test helps your doctor see why you're having trouble swallowing.
Tell your doctor if:
Your doctor may tell you not to eat anything after midnight the night before the test.
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.
After the test, you may feel bloated and a little nauseated.
The barium in the food is not harmful.
Some people gag when they drink 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.
If your doctor thinks you may be at risk for complications, he or she may use a special type of contrast material (Gastrografin) instead of barium.
There is always a small chance of damage to cells or tissue from being exposed to any radiation, even the low level of radiation used for this test.
