A barium swallow is a special type of X-ray test that helps your doctor take a close look at the back of your mouth and throat, known as the pharynx, and the tube that extends from the back of the tongue down to the stomach, known as the esophagus.

Your doctor may ask you to do a barium swallow to help diagnose any conditions that make it difficult for you to swallow or if they suspect that you have a disorder of the upper gastrointestinal (GI) tract. Your upper GI tract includes:

• the esophagus
• the stomach
• the first part of the small intestine, called the duodenum

To do a barium swallow, you swallow a chalky white substance known as barium. It’s often mixed with water to make a thick drink that looks like a milkshake. When it’s swallowed, this liquid coats the inside of your upper GI.

Barium absorbs X-rays and looks white on X-ray film. This helps highlight these organs, as well as their inside linings and the motion of your swallowing, on the X-ray image. These images help your doctor diagnose any disorders of the GI tract.
