Esophageal hyperplasia may be related to esophageal reflux, esophageal cancer and other diseases, which are more important and need to pay more attention. 1. Esophageal reflux: when the relaxation of cardia muscle is unable to block the reflux of gastric acid secreted by gastrointestinal tract, the esophagus is stimulated by long-term corrosion of gastric acid, forming esophageal ulceration and causing reflux esophagitis, which will lead to esophageal hyperplasia. 2. Esophageal cancer: esophageal cancer belongs to one kind of malignant tumors, due to the fact that the esophagus of patients with esophageal cancer is seriously damaged at the local lesion site after the onset of esophageal cancer, which leads to abnormal hyperplasia of esophagus. There may be other reasons for esophageal hyperplasia, so it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of doctors.
