Chronic gastritis with hyperplasia is hyperplasia in the stomach. Including reactive hyperplasia and heterogeneous hyperplasia. 1. Reactive hyperplasia: reactive hyperplasia can occur in the gastric mucosa of chronic gastritis, such as epithelial hyperplasia of gastric mucosa at the small concavity of the stomach, thickening of the mucosal muscular layer, and hyperplasia of fibrous connective tissue. 2. Heterotrophic hyperplasia: it is the result of excessive proliferation and reduced differentiation in the process of cell regeneration, which results in structural and functional changes. Morphologically, it is characterized by cellular heterogeneity and glandular structure disorder; endoscopically, it can occur in elevated and depressed lesions. Heteroplasia is a precancerous lesion of gastric cancer. If you find chronic gastritis with hyperplasia, you should go to the hospital in time to clarify the type of hyperplasia and carry out treatment in time to reduce the possibility of cancer.
