Acute gastritis is a sudden inflammation or swelling in the lining of the stomach. It causes severe and nagging pain. However, the pain is temporary and usually lasts for short bursts at a time. Acute gastritis occurs when the lining of your stomach is damaged or weak. This allows digestive acids to irritate the stomach. There are many things that can damage your stomach lining. The causes of acute gastritis include: medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids.
Acute gastritis is usually caused by an irritant or infection, and can result in an acute upset stomach, but usually settles quickly with simple treatments when the cause is removed. Chronic gastritis is a condition in which the stomach lining is damaged long-term, often due to infection by H. pylori. Chronic gastritis does not usually cause indigestion or pain, but severe damage may result in anemia due to vitamin B12 deficiency.
