In addition to narrowing of the esophagus, paralysis of the recurrent laryngeal nerves on both sides of the larynx is also a major cause of choking. Many people will suffer from narrowing of the esophagus due to inflammation or tumors, which will cause choking in eating, especially when eating hard food. Due to the narrowing of the esophagus, the flow of water will be affected when drinking, and some people will easily choke when they drink water too fast or ingest a large amount of water at one time. When the recurrent laryngeal nerve is paralyzed, the laryngeal nerve response will be impaired, and the swallowing action can not be better coordinated, so when drinking water, it will also be easy to choke. Patients with esophageal stenosis can consider medication, endoscopic surgery, or surgery to improve the condition. Patients with recurrent laryngeal nerve palsy need to undergo a CT scan to confirm the diagnosis and treat the cause. Choking caused by cerebral infarction requires rehabilitation and treatment of the original disease.
