What is gastritis?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Gastritis  is a potentially painful condition where the lining of your stomach becomes inflamed. Causes of gastritis include infection, injury, problems with the immune system, some drugs, excessive alcohol consumption, or stress.

Gastritis is not a single disease, but several different conditions that cause an 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.

The most common symptoms are abdominal upset or pain. Other symptoms are belching, abdominal bloating, nausea, and vomiting, or a feeling of fullness or burning in the upper abdomen. Blood in your vomit or black stools may be a sign of bleeding in the stomach, which may indicate a serious problem requiring immediate medical attention.

This answer is based on source information from the National Institute of Diabetes and Digestive and Kidney Diseases.

Gastritis occurs when the lining of the stomach becomes inflamed, resulting in stomach pain, nausea and vomiting. There are several types of gastritis, including erosive gastritis, acute stress gastritis, radiation gastritis, postgastrectomy gastritis, atrophic gastritis, eosinophilic gastritis, Menetrier's disease, and lymphocytic gastritis. Gastritis can be mild or serious, but for most people symptoms improve with treatment.
