Gastric sinus erosion is generally more difficult to heal on its own, and needs to be treated promptly and aggressively, the specific recovery time is related to the severity of the erosion as well as the treatment. Gastric sinus is located in the lower part of the stomach body, the pylorus of gastric sinus is connected to the duodenum, food passes through the gastric sinus and then enters the duodenal intestinal lumen to participate in digestion and absorption. Gastric sinus is one of the most inflammatory parts of the stomach, often with abdominal pain, bloating, nausea, belching and other uncomfortable symptoms, which can be caused by long-term friction of food and Helicobacter pylori infection. Generally, it can be treated with proton pump inhibitors and gastric mucosal protection drugs to heal the erosion and improve the symptoms. If the erosion is accompanied by atrophy, we should be highly alert to the occurrence of cancer, and regular gastroscopy is needed. During the period of illness, one should not drink alcohol or smoke, and should pay attention to rest and take a light and easy-to-digest diet in order to avoid repeated episodes. Meanwhile, gastroscopy should be repeated regularly to monitor the development of the disease.
