[6] Achlorhydria induces G cell (gastrin-producing) hyperplasia, which leads to hypergastrinemia.
Inflammation of the stomach by infection from any cause is called gastritis, and when including other parts of the gastrointestinal tract called gastroenteritis. When gastritis persists in a chronic state, it is associated with several diseases, including atrophic gastritis, pyloric stenosis, and gastric cancer.
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.

[43] This term was coined also to indicate the presence of thyroid autoantibodies or autoimmune thyroid disease in patients with pernicious anemia, a late clinical stage of atrophic gastritis. [44]
