Localized mucosa of the gastric sinus showing atrophic signs means that when gastroscopy is done, it is found that the localized mucosa of the gastric sinus is atrophied, the folded mucosa disappears, the glands are reduced, and the color becomes lighter. When atrophy occurs in the mucosa of the gastric sinus, it affects the digestive function and symptoms such as bloating, abdominal pain, nausea and belching may occur. The pathology progresses to enterosis and atypical hyperplasia, requiring long-term endoscopic follow-up. Gastric sinus mucosal atrophy should be followed up by a doctor. If there is dyspepsia you can take gastric stimulants such as domperidone and mosapride under doctor’s supervision to promote gastric peristalsis and help digest food. And receive endoscopy for regular follow-up to prevent cancer. In normal times, avoid eating too rough, irritating food and pickled products, etc., and eat more easy-to-digest food.
