Gastritis (stomach inflammation) is an inflammation of the stomach lining. The main acute causes are excessive alcohol consumption or prolonged use of nonsteroidal anti-inflammatory-drugs (also known NSAIDs) such as aspirin or ibuprofen. Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections.
Gastritis disease may occur suddenly (acute gastritis) or it can occur slowly over time (chronic gastritis). In some cases, gastritis can lead to ulcers and an increased risk of stomach cancer. For most people, however, gastritis isn’t serious and improves quickly with treatment.
