There is erosive gastritis, for which the common causes are stress, alcohol, some drugs, such as aspirin and other nonsteroidal anti-inflammatory drugs , and Crohn's disease. And, there is non-erosive gastritis, for which the most common cause is a Helicobacter pylori infection. [15] [1]
A greater cytotoxicity will result in the change from a non-atrophic gastritis to an atrophic gastritis, with the loss of mucous glands. This condition is a prequel to the development of peptic ulcers and gastric adenocarcinoma. [149] Eradication of H. pylori is recommended to treat the infection, including when advanced to peptic ulcer disease.
Inflammation of the stomach by infection from any cause is called gastritis, and when including other parts of the gastrointestinal tract called gastroenteritis.

[38] [39] Autoimmune atrophic gastritis, is localised to the body of the stomach, where parietal cells are located. [36] Antibodies to intrinsic factor and parietal cells cause the destruction of the oxyntic gastric mucosa, in which the parietal cells are located, leading to the subsequent loss of intrinsic factor synthesis.
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
