Pathological characteristics of chronic atrophic gastritis

Chronic atrophic gastritis is atrophic gastritis, atrophic gastritis pathological features include gastric mucosa epithelial layer thinning, inherent glands decreased, cellular dysplasia and intestinal metaplasia.

1, gastric mucosa epithelial layer thinning

atrophic gastritis patients gastric mucosa epithelial layer thinning, so that the protective function of gastric mucosa weakened, vulnerable to damage.

2, inherent glands decreased

atrophic gastritis patients gastric mucosa inherent glands decreased, so that the secretion and digestive function of gastric mucosa decreased.

3, cellular dysplasia

gastric mucosa epithelial cells appear dysplasia, may be transformed into gastric cancer.

4, intestinal metaplasia

part of gastric mucosa epithelial cells replaced by intestinal epithelial cells, the formation of intestinal metaplasia, so that gastric mucosa digestion and absorption function is affected.
