If the esophagus is observed with an esophagoscope, the esophagus of a person who has been drinking a considerable amount of hard liquor every night for several decades can be seen to be swollen throughout the mucous membrane, with many places peeling off and bleeding. Even if the esophagitis improves, but because it has just begun to improve every night and drink, there is no possibility of complete healing. Similarly, chronic esophagitis can result if irritants, hot and hard foods, etc. continue to be ingested. The patient may experience pain behind the sternum, foreign body, burning and heartburn.

Patients with chronic esophagitis should first rest the esophagus, eliminate the cause of the disease (e.g., abstaining from alcohol and irritants, etc.), and eat mainly fluids and soft foods to protect the esophageal mucosa. Can also take drugs internally.
