How is gastritis diagnosed?

Dr. Jeanne Morrison, PhD
Family Practitioner

Gastritis may be diagnosed based on your symptoms and medical history. A certain diagnosis would require testing, mainly an endoscopy to view the lining of the stomach and possibly take a tissue sample. Your doctor may order blood and stool tests to look for causes of the gastritis. (Blood in the stool may be a sign of stomach bleeding, for instance, as would be anemia.) Other tests are used to help determine the cause of gastritis. A breath test may be used to confirm the presence of H. pylori infection. In some situations, your doctor may perform an X-ray--possibly including a barium swallow to help make problems like ulcers visible.
