Usually, esophageal bulge is mainly considered to be related to esophageal mesenchymal tumor, esophageal cyst, esophageal cancer, etc., which usually cannot be self-healed. 1. Esophageal mesenchymal tumor: the cause is unknown and may be related to gene mutation and environmental factors. Usually, esophageal mesenchymal tumor will not be cured by itself, and patients need to be actively treated and there is a chance of recurrence. Esophageal mesenchymal tumors are prone to poor appetite, epigastric pain, difficulty in swallowing and other uncomfortable symptoms, which will affect the quality of life. 2. Esophageal cysts: Esophageal cysts can also cause bulging of the esophagus in some patients, and they cannot be cured by themselves. The cause of the disease is still unclear, but it often causes wheezing, dyspnea, dysphagia, reflux, vomiting, retrosternal pain and other uncomfortable symptoms. 3. Esophageal cancer: it belongs to malignant tumors, which will not be cured by itself and has the chance of recurrence. The occurrence of esophageal cancer is related to hereditary factors and long-term improper diet, etc. Patients mainly manifest burning sensation behind the sternum, hoarseness, difficulty in swallowing and so on. Esophageal bulge may also be caused by esophageal varicose vein, external organ compression, etc. It is suggested that people with esophageal bulge should have a further detailed examination and follow the doctor’s instruction after clarifying the cause of the disease, and should not use medicines or prescriptions indiscriminately on their own.
