What is an Upper Gastrointestinal Study?
An upper gastrointestinal study (GI) is an examination of the esophagus, stomach and duodenum.
The purpose of the Upper GI is to study the form and function of the esophagus, stomach and duodenum, as well as to detect abnormal anatomical and functional conditions. Some of the more common abnormalities seen are peptic ulcers, hiatal hernias, acute or chronic gastritis, carcinomas and benign lesions such as polyps or diverticula.
How to Prepare for an Upper GI Study
Do not eat or drink after midnight the night before the procedure is to be
performed.
What to Expect During the Procedure
Under direct supervision by the radiologist, you will be asked to drink barium. He will then be able to evaluate the structure of the anatomy of the upper gastrointestinal tract. After the initial examination by the radiologist, the x-ray technologist will then obtain further views of the stomach.
