Gastric glandular low-grade intraepithelial tumor is a low-grade precancerous lesion with a chance of becoming cancerous. After a clear diagnosis of gastric glandular low-grade intraepithelial tumor, it must be observed and treated under the guidance of a doctor. When the lesion site is small and there is no digestive symptom, only regular gastroscopy is needed, and generally no special treatment is needed. Patients should improve their life style, avoid stimulating food intake, quit smoking and drinking, ensure a light diet, and avoid staying up all night and too much mental stress. At the same time, they should follow up regularly according to the doctor’s instructions to avoid aggravation of the condition. If there are digestive symptoms, you can give regular treatment to inhibit gastric acid secretion, protect gastric mucosa, and then avoid spicy and stimulating food, such as onion, ginger, garlic, chili pepper and so on, and then you can have a soft and easy-to-digest, low-fat diet, and have regular review of gastroscopy. If it turns into high-grade endomatosis, endoscopic mucosal debridement is needed, usually without traditional surgery, when the patient has obvious symptoms, it should be treated by endoscopic minimally invasive surgery, and the patient should be followed up regularly according to the doctor’s instructions in the prognosis to avoid recurrence. When gastric glandular low-grade epithelioma is found, patients should go to the hospital in time for examination and evaluation by professional doctors, and appropriate treatment should be carried out.
