Chronic gastritis with hyperplasia and erosion is not serious in most cases. In most cases, chronic gastritis with erosion can be seen on gastroscopy as localized spots of bleeding and erosion foci in the gastric mucosa. If the hyperplasia is inflammatory reactive hyperplasia, it is not too serious, and acid-suppressing drugs such as famotidine and omeprazole can be taken to reduce the inflammation, and the hyperplasia can be improved. Overall, chronic gastritis with hyperplasia and erosion is not too serious, but it also depends on the specific situation, which mainly depends on whether the chronic gastritis has the basis of atrophy, the degree of erosion and whether it is accompanied by the manifestation of precancerous lesions. The above drugs are prohibited for those who are allergic to them, and all should be taken in accordance with medical advice. If the patient is diagnosed with chronic gastritis, it is recommended to go to a regular hospital in time, after clarifying the cause of the disease, under the guidance of the doctor to carry out targeted treatment, in order to reduce the adverse effects of the disease.
