Reflux esophagitis of grade LA B is not very severe, indicating one or more esophageal mucosal injuries, approximately five millimeters in length, but without confluence lesions. Patients with reflux esophagitis should take medication regularly, must undergo periodic gastroscopy, and the selection of specific medications and their dosage should be under the guidance of a doctor. Commonly, proton pump inhibitors can be used to suppress gastric acid secretion, and medications like aluminum hydroxide magnesium carbonate can be used to protect the gastric and esophageal mucosa. Additionally, drugs like mosapride and itopride can be used to promote esophageal motility, as well as gastric motility.
