Upper Gastrointestinal Series[edit | edit source]

The Upper Gastrointestinal Series (UH-per GAS-troh-in-TES-tih-nul SEER-eez), often referred to as the upper GI series, is a diagnostic imaging procedure that involves capturing a series of x-ray pictures of the esophagus, stomach, and duodenum (the initial segment of the small intestine).

Procedure[edit | edit source]

During the test, the patient is required to consume a liquid solution that contains barium sulfate. This compound is a derivative of the silver-white metallic element, barium. After ingestion, the barium sulfate functions as a contrast medium, effectively coating the internal lining of the upper gastrointestinal tract. This coating enhances the visibility of the tract's inner walls on the x-ray images, allowing potential abnormalities or issues to be identified with greater clarity.

Purpose[edit | edit source]

The Upper Gastrointestinal Series is utilized to:

  • Diagnose abnormalities or diseases in the upper gastrointestinal tract.
  • Investigate symptoms like persistent abdominal pain, nausea, vomiting, or difficulty swallowing.
  • Examine conditions such as ulcers, tumors, or inflammation in the esophagus, stomach, or duodenum.

Risks and Considerations[edit | edit source]

While the procedure is generally considered safe, there may be minor side effects related to the consumption of the barium sulfate solution, including constipation or white-colored stools. Patients are advised to increase fluid intake post-procedure to help expel the barium from the system.
