Test: Barium Swallow

A barium swallow is a test used to visualize the oesophagus, the tube that connects the mouth to the stomach. The test can detect disorders or abnormalities of the oesophagus, such as narrowing or tumours. A barium solution is used because it shows up on X-rays, which are taken continuously to monitor the flow of the solution. The barium may cause temporary constipation.

During the procedure

While standing in front of the X-ray machine, you are asked to swallow a barium solution as a series of X-rays is taken. The procedure takes about 15 minutes to complete.

Results
