Dysphagia is a feeling of obstruction and stagnation produced by the obstruction of the process of swallowing and transportation of food from the oral cavity to the stomach, which can be categorized into mechanical dysphagia and dynamic dysphagia according to the mechanism. 1. Mechanical dysphagia is mechanical obstruction during food delivery, such as inflammation of oropharynx, pharyngeal tumors, esophageal lesions such as benign esophageal tumors, reflux esophagitis, esophageal cancer and so on, which will lead to luminal narrowing. Secondly, peripheral tissue lesions such as mediastinal space occupation and mass in the posterior pharyngeal wall can also compress the lumen. 2. Dynamic dysphagia is mainly the dysfunction of nerves and muscles that control and assist swallowing, such as oropharyngeal muscle paralysis, medullary paralysis, myasthenia gravis, rabies, tetanus and so on. If you feel difficulty in swallowing food or have a sense of obstruction, it is recommended to go to the hospital as soon as possible to improve the auxiliary examination, clear diagnosis and then follow the doctor’s instructions for appropriate treatment.
