Upper GI Series

Also known as: UGI series, UGI test, upper gastrointestinal series.

What is upper GI series?

An upper GI series is an imaging test that is used to examine and possibly diagnose conditions in the upper gastrointestinal tract. It uses barium liquid to give doctors a better view of the components of the upper GI during the test. It can be used to diagnose a variety of conditions that affect the digestive system.

What happens during the procedure?

While standing in front of an X-ray machine, the patient drinks barium. The patient then lies on a table while X-rays are performed as the barium moves through the digestive tract. The doctor may press on the body in order to move the barium around and get a clearer picture of certain parts of the GI tract.

Is any special preparation needed?

The patient may need to avoid food, drink, gum, smoking or certain medications prior to the procedure.

What are the risk factors?

Intestinal blockage, constipation or allergic reactions are potential complications of an upper GI series.
