Gastritis is an inflammation, irritation, or erosion of the lining of the stomach that 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. It may also be caused by Helicobacter pylori (H. pylori), a bacterium that lives in the mucous lining of the stomach and can lead to ulcers and even stomach cancer; pernicious anemia; and bile reflux. The most common symptoms of gastritis include nausea or recurrent upset stomach, abdominal bloating and pain, vomiting, a burning feeling in the stomach, and black or bloody stools.
