What is an Upper GI?
An upper GI, also called gastrointestinal tract radiography, is an X-ray examination of the pharynx, esophagus,
stomach and first part of the small intestine (also known as the duodenum) using a special form of X-ray called fluoroscopy
and an orally ingested contrast material called barium. In addition to drinking barium, you may also be given baking-soda
crystals (similar to Alka-Seltzer) to further improve the images. This procedure is called an air-contrast or double-contrast upper GI.
What are common reasons to have an Upper GI?
- Difficulty swallowing
- Chest and abdominal pain
- Reflux (a backward flow of partially digested food and digestive juices)
- Unexplained vomiting
- Severe indigestion
- Blood in the stool (indicating internal GI bleeding)
Is there any preparation for the Upper GI procedure?
- Inflammation of the esophagus, stomach and duodenum
- Hiatal hernias
- Abnormalities of the muscular wall of GI tissues
