The Upper GI studies abnormalities of the upper gastrointestinal tract. Many patients will have an upper GI for symptoms including nausea, vomiting, reflux, dyspepsia or other digestive symptoms.
To prepare, patients are asked to fast after midnight the night before the exam.
Once in the exam room, you will be given 4 ounces of barium to drink, which is about the consistency of a melted milkshake.
During the Upper GI, the radiologist watches the barium go from the esophagus and into the stomach on an X-ray monitor. This procedure lasts for about 30 minutes and there is no discomfort or any side effects for patients having this procedure.
