Mild atrophy of gastric sinus with mild intestinal epithelial hyperplasia is mostly manifested as a precancerous lesion, which may gradually develop into gastric cancer. Intestinal epithelial hyperplasia of the stomach refers to the appearance of abnormal intestinal epithelium in the normal gastric sinus, which manifests as atypical hyperplasia, and is clinically recognized as a precancerous lesion, which is mainly associated with long-term chronic atrophic gastritis that is not effectively controlled. If no active intervention is taken, it may develop into gastric cancer and reduce the survival of patients. For mild intestinal epithelial hyperplasia, patients can take medication or surgical resection of the lesion at an early stage, which can achieve good curative effect. Patients are advised to take treatment under the guidance of doctors as early as possible, and must not use drugs blindly to avoid further development of the condition.
