When You Have Gastritis

Acids may damage the stomach lining when the built-in defenses of the stomach don’t function as they should. The stomach lining can then become inflamed. When this occurs, it is called gastritis.

Causes of Gastritis

Gastritis has many causes. They may include:

  • Aspirin and anti-inflammatory medications

  • Tobacco use

  • Alcohol use

  • Helicobacter pylori (H. pylori) bacteria

  • Trauma from injuries, burns, or major surgery

  • Critical illness or autoimmune disorders
