The antrum is the lower part of the stomach, close to where the stomach empties into the intestine, notes the American Cancer Society. Gastritis is a problem with the lining of the stomach. It can be characterized as irritated, eroded or inflamed. Gastritis can have a sudden onset or gradually get worse. Common causes of acute gastritis include stress, consuming excessive amounts of alcohol or taking medications such as aspirin that irritate the lining of the stomach, states WebMD. Common causes of chronic gastritis include infection with a bacterium called Helicobacter pylori, pernicious anemia or bile reflux. Symptoms of gastritis include nausea, vomiting, abdominal pain and loss of appetite.
