Gastritis is not a single disease, but several different conditions that all have inflammation of the stomach lining. Gastritis can be caused by drinking too much alcohol, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen, or infection with bacteria such as Helicobacter pylori (H. pylori). Sometimes gastritis develops after major surgery, traumatic injury, burns, or severe infections. Certain diseases, such as pernicious anemia, autoimmune disorders, and chronic bile reflux, can cause gastritis as well.

Gastritis, an inflammation or irritation of the lining of the stomach, is not a single disease. Rather, gastritis is a condition that has many causes. Common to all people with gastritis is pain or discomfort in the upper part of the belly (abdomen), sometimes called dyspepsia.
Gastritis may occur suddenly (acute gastritis), or it can occur slowly over time (chronic gastritis). In spite of the many conditions associated with gastritis, the signs and symptoms of the disease are very similar: a burning pain in your upper abdomen and, occasionally, bloating, belching, nausea or vomiting.
Gastritis is an inflammation of the stomach lining. While the lining of the stomach is quite strong and can withstand strong acid, drinking too much alcohol, eating spicy foods, or smoking can cause the lining to become inflamed and irritated.
Symptoms
The symptoms of gastritis depend on how acute it is and how long it has been present. In the acute phase, there may be pain or gnawing in the upper abdomen, nausea and vomiting. In the chronic phase, the pain may be dull and there may be loss of appetite with a feeling of fullness after several bites of food. Very often, there are no symptoms at all. If the pain is severe, there may be an ulcer as well as gastritis.
Acute stress gastritis, actually a form of erosive gastritis, is caused by a sudden illness or injury. The injury may not even be to the stomach. For example, extensive skin burns and injuries involving major bleeding are typical causes. Exactly why serious illness can lead to gastritis is not known but may be related to decreased blood flow to the stomach or to impairment of the stomach lining's ability to protect and renew itself.
Acute gastritis occurs suddenly and is more likely to cause nausea and burning pain or discomfort in your upper abdomen. Chronic gastritis develops gradually and is more likely to cause a dull pain and a feeling of fullness or loss of appetite after a few bites of food. For many people, though, chronic gastritis causes no signs or symptoms at all.
Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress or the use of certain medications such as aspirin or other anti-inflammatory drugs.
