Chronic gastritis and sinus erosion are not severe, but only the presence of sinus erosion on top of chronic gastritis. However, the foci of erosion are only limited to the gastric mucosa and are small in extent. Chronic gastritis is chronic superficial gastritis, so it is not serious. For erosive lesions, the doctor will routinely clamp the erosive biopsies for pathological biopsy to clarify the nature of the lesion, which in most cases is inflammatory. If there is atrophy of the gastric mucosa, a diagnosis of chronic atrophic gastritis with erosion will be made. The doctor suggests that chronic gastritis with sinus erosion indicates a relatively mild disease, so the patient does not need to be nervous. In terms of treatment, it is best to cooperate with the doctor in using acid-suppressing drugs in combination with drugs that promote mucosal repair. The effect of oral omeprazole, lansoprazole and other proton pump inhibitors, combined with rehabilitation of new liquid treatment is more satisfactory, as long as the regular compliance with medical advice can be cured.
