Gastritis is a painful inflammation of the stomach lining. It has a number of causes. Treatment can ease the symptoms.
The stomach
To digest the food you eat, your stomach makes strong acids and enzymes. These don't harm the lining of a healthy stomach. But acids may irritate the lining when the stomach doesn't work as it should. That's called gastritis.
