Understanding Gastritis
Gastritis is a painful inflammation of the stomach lining. It has a number of causes. Gastritis and its symptoms can be eased with treatment. Work with your healthcare provider to find ways to treat your symptoms.
The stomach
To digest the food you eat, your stomach makes strong acids and enzymes. A healthy stomach has built-in defenses that protect its lining from damage by these acids and enzymes.
When you have gastritis
Acids may damage the stomach lining when the built-in defenses of the stomach don’t work as they should. The stomach lining can then become inflamed. When this happens, it is called gastritis.
Causes of gastritis
Gastritis has many causes. They may include:
-
Aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs)

Tobacco use
