Although your doctor is likely to suspect gastritis after talking to you about your medical history and performing an exam, you may also have one or more of the following tests to pinpoint the exact cause.





  • X-ray of your upper digestive system. Sometimes called a barium swallow or upper gastrointestinal series, this series of X-rays creates images of your esophagus, stomach and small intestine to look for abnormalities. To make the ulcer more visible, you may swallow a white, metallic liquid (containing barium) that coats your digestive tract.

Using a fiber-optic endoscope, your doctor can view your esophagus, stomach and part of your duodenum. This video shows removal of a specimen from a suspicious area near the outlet of the stomach.
