Non-atrophic gastritis with erosion is a state where there is erosion of the gastric mucosa on top of superficial gastritis, which in layman’s terms is a state between superficial gastritis and gastric ulcer. Erosion is a superficial tissue defect of the skin and mucosa, while ulcers are deeper tissue defects, so literally erosion is lighter than ulcers but heavier than superficial gastritis. Common causes of erosive gastritis include Helicobacter pylori (HP) infection, alcoholism, eating spicy and stimulating foods, long-term use of non-steroidal anti-inflammatory drugs, bile reflux, etc. To treat and prevent erosive gastritis, we need to start from the cause of the disease, such as anti-HP treatments, adjusting dietary habits, and the use of acid-suppressing drugs. Therefore, in order to treat and prevent this disease, we also need to clarify the cause of the disease, and start from the cause of the disease, in order to make celiac gastritis get better, so as to slow down the further progress of the disease. If there is any discomfort, it is necessary to consult a doctor in time and use medication and treatment under the guidance of the doctor.
