what is gastric atrophy
Atrophic gastritis (also known as Type A or Type B Gastritis more specifically) is a process of chronic inflammation of the stomach mucosa, leading to loss of gastric glandular cells and their eventual replacement by intestinal and fibrous tissues.ype A gastritis primarily affects the body/fundus of the stomach, and is more common with pernicious anemia. Type B gastritis primarily affects the antrum, and is more common with H. pylori infection.
