How is gastritis diagnosed?

Gastritis is diagnosed based on the patient's symptoms and history of a previous diagnosis and treatment of gastritis, alcohol consumption, and use of NSAIDs. Definitive diagnosis of gastritis is made by identifying the underlying cause of the gastric mucosal inflammation and/or by tissue (gastric) biopsy. For example, the major infective cause of gastritis is Helicobacter pylori (H. pylori). This bacterium can be detected by breath, blood, stool, immunological and biopsy tests. Although the bacterium can be cultured from the patient, this is seldom attempted. Other pathogens can be identified using culture, stool, and immunological tests.

Biopsy of the stomach mucosa, done during endoscopy examinations, is often used in patients to identify the causes of chronic gastritis and may allow visualization of mucosal erosions and other stomach mucosal changes. Abdominal X-rays or barium studies (upper or lower) may demonstrate the presence of thickened mucosa and folds that are signs of inflammation in the stomach.

Your doctor can help determine which tests should be done, including ancillary tests that may help identify other causes of the non-specific symptoms commonly found with gastritis.
