Esophagitis does not usually cause submucosal elevation of the esophagus; the symptoms of esophagitis are edema and congestion of the esophageal mucosa. Esophagitis is caused by edema and congestion of the mucous membrane of the esophagus due to repeated irritation of the superficial mucous membrane or the deeper mucous membrane tissues of the esophagus. The main causes of submucosal elevation of esophagus are smooth muscle tumor, hemangioma, mesenchymal tumor of esophagus, malignant tumors originated from the muscle layer, and even compression of extraluminal tissues, such as compression by local enlarged lymph nodes, compression by the surrounding organs, and most of them are benign lesions. It should be noted that in daily life, the diet should be regular, three meals at regular intervals, and avoid overeating. Patients with esophagitis and submucosal elevation of the esophagus need to be treated under the guidance of a professional doctor.
