Gastric mucosa thickening

Thickening of gastric mucosa is one of the clinical manifestations of "chronic atrophic gastritis" (intestinalization, atypical hyperplasia), and chronic atrophic gastritis is a common gastric disease. Arteriosclerosis, insufficient gastric blood flow, and the habit of tobacco, alcohol, tea, etc., can easily damage the barrier function of the gastric mucosa and cause chronic atrophic gastritis. In atrophic gastritis, the gastric mucosa atrophies and is replaced by intestinal epithelial cells, that is, intestinal metaplasia; when inflammation continues to evolve, the cell growth is atypical, that is, interstitial; even cell proliferation causes carcinogenesis.
