Atrophic gastritis under low power. H&E stain. Autoimmune metaplastic atrophic gastritis (AMAG) is an inherited form of atrophic gastritis characterized by an immune response directed toward parietal cells and intrinsic factor. [6] Achlorhydria induces G cell (gastrin-producing) hyperplasia, which leads to hypergastrinemia.
Stomach biopsy, to test for gastritis and other conditions [27] The OLGA staging frame of chronic gastritis on histopathology. Atrophy is scored as the percentage of atrophic glands and scored on a four-tiered scale. No atrophy (0%) = score 0; mild atrophy (1–30%) = score 1; moderate atrophy (31–60%) = score 2; severe atrophy (>60%) = score 3.

“We are at the point where long-term food and nutrition security requires diversifying the human diet by breeding and making genetic improvement to nutrient-rich, so-called ‘minor crops ...
PA may be considered as an end stage of autoimmune atrophic gastritis, a disease characterised by stomach atrophy and the presence of antibodies to parietal cells and intrinsic factor. [38] [39] Autoimmune atrophic gastritis, is localised to the body of the stomach, where parietal cells are located. [36]
