Upper GI

An Upper GI Series is an X-ray exam of your upper digestive tract, the area from your mouth to the start of your small intestine or duodenum.

An upper GI series uses a special form of X-ray called fluoroscopy, which provides a view of how your GI tract looks and functions. The exam also uses a contrast material called barium to improve the X-ray images.

An upper GI exam helps to assess overall digestive function and detect:

  • Ulcers
  • Tumors
  • Inflammation of the esophagus, stomach and duodenum
  • Hiatal hernias
  • Scarring
  • Blockages
  • Abnormalities of the muscular wall of gastrointestinal tissues

The procedure may help diagnose various symptoms, including:

  • 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)
