Adenoepithelial mild intestinal epithelialization means that intestinal-type epithelial cells replace the epithelial cells of the gastric mucosa. Mild intestinal epithelialization of adenoepithelium means that the space left by gastric atrophy is filled by intestinal-type epithelial cells, which is most commonly seen in atrophic gastritis or bile reflux gastritis, and so on. Patients are advised to have regular gastroscopy follow-up and examination, usually once every 1-2 years. Mild intestinal epithelialization does not need to be particularly nervous, and regular gastroscopy and follow-up are most important. It is usually recommended that patients avoid eating spicy, stimulating, fried food, avoid fatigue, stay up late, etc. If the test results are abnormal, it is recommended that the patient should be timely examined. If the test results are abnormal, it is recommended to consult a doctor in a timely manner to clarify the cause of the disease, and follow the doctor’s instructions for targeted treatment or therapy.
