Type A atrophic gastritis is an autoimmune disease, which means that the patient’s mural cell antibodies and internal factor antibodies lead to a decrease in gastric acid secretion and a lack of internal factors, resulting in insufficient absorption of vitamin B12 and pernicious anemia, which is also called chronic atrophic gastric body inflammation due to the fact that it mainly occurs in the body of the stomach.
Type B atrophic gastritis is mainly caused by Helicobacter pylori infection, because it mainly occurs in the gastric sinus, so it is also called chronic atrophic gastritis.
