What happens during a barium swallow?
A barium swallow is most often done by a radiologist or radiology technician. A radiologist is a doctor who specializes in using imaging tests to diagnose and treat diseases and injuries.
A barium swallow usually includes the following steps:
You may need to remove your clothing. If so, you will be given a hospital gown.
You will be given a lead shield or apron to wear over your pelvic area. This protects the area from unnecessary radiation.
You will stand, sit, or lie down on an x-ray table. You may be asked to change positions during the test.
You will swallow a drink that contains barium. The drink is thick and chalky. It's usually flavored with chocolate or strawberry to make it easier to swallow.
While you swallow, the radiologist will watch images of the barium traveling down your throat to your upper GI tract.
You may be asked to hold your breath at certain times.
The images will be recorded so they can be reviewed at a later time.
