Upper G.I. Series

These procedures allow the radiologist to look at the gastrointestinal tract using contrast material called barium. Some of the reasons you may need this procedure are difficulty swallow, vomiting, abdominal pain, weight loss, chronic diarrhea, ulcers, polyps, and if you have a history of Crohn’s disease.


  • Nothing to eat or drink after midnight
  • You will be given some barium to drink


The radiologist will watch the movement of the barium as it moves through your esophagus, stomach and into the small intestines. Pictures will be taken at different times throughout the study.


After the exam, drink plenty of fluids and you can return to your normal activities.
