The reasons for frequent choking on food are as follows: First, the speed of eating is too fast and the vagus nerve under the esophageal mucosa is stimulated. Second, diseases of the esophagus itself, such as esophagitis, esophageal ulcer, esophageal cancer and other esophageal lumen narrowing caused. Third, diseases outside the esophagus, such as mediastinal tumors and lung diseases compressing the lumen of the esophagus, resulting in the narrowing of the lumen of the esophagus. Therefore, if you choke often, you should go to the gastroenterology, thoracic surgery or respiratory medicine department of the hospital as soon as possible, and perform chest CT, gastroscopy and other related examinations in time to clarify the cause. If it is simply caused by eating too fast, patients need to slow down when eating, chew and swallow slowly. If it is caused by intra-esophageal or extra-esophageal organic disease, it should be treated as soon as possible.
