Reflux esophagitis grade LA-A is not very severe. It is the lowest grade in the classification of reflux esophagitis, indicating that one or more areas of the esophageal mucosa are damaged, but the length of the lesions is less than five millimeters. If reflux esophagitis grade LA-A is present, the use of proton pump inhibitors, which suppress gastric acid secretion, can be considered for treatment to reduce the damage and irritation to the esophageal mucosa from excessive gastric acid secretion. Additionally, medications such as aluminum-magnesium carbonate and sucralfate can be used to protect the esophageal and gastric mucosa. The specific choice of medication and the dosage should be used under the guidance of a clinical physician.
