Gastritis is a painful inflammation of the stomach lining. It has a number of causes. Gastritis and its symptoms can be relieved with treatment. Work with your healthcare provider to find ways to treat your symptoms.
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.
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 happens, it is called gastritis.
Gastritis has many causes. They may include:
Aspirin and anti-inflammatory medicines
Helicobacter pylori (H. pylori) bacteria
Trauma from injuries, burns, or major surgery
Critical illness or autoimmune disorders
With gastritis, you may notice one or more of the following:
A burning feeling in your upper belly
Pain that happens after eating certain foods
Gas or a bloated feeling in your stomach
Nausea with or without vomiting
Loss of appetite
Feeling full quickly
