upper GI
Esophagus and stomach
Upper GI refers to the upper gastrointestinal tract—the esophagus, stomach, and duodenum.
The term appears most often in medical contexts: an upper GI series or upper GI endoscopy examines these organs for ulcers, tumors, or other abnormalities.
The doctor ordered an upper GI to check for reflux damage.
