Gastric erosion is also known as erosive gastritis, and the classification is mainly based on the number of lesions, which is divided into several different levels: one, two and three. 1. Grade 1: relatively speaking, the condition is relatively mild, only in the gastric mucosa appear single erosion lesions, and the area is not very large. 2. Grade 2: the disease has progressed to a certain extent compared to Grade 1, manifesting itself in 2~5 foci of erosion, but the single foci are still with certain limitations. 3.Grade 3: has been manifested as multiple, extensive erosion foci, the number of at least 6 or more, and the situation is still relatively serious. Gastric erosion needs to be treated according to the individual’s condition, using antibacterial, antacid and gastric mucosal protection drugs such as levofloxacin, omeprazole and bismuth salicylate under the guidance of the doctor, so as not to aggravate the condition continuously.
