Patients who choke and wake up with their own saliva after falling asleep are mainly considered to be the result of the combined effect of the following two aspects: first, patients may tilt their heads back excessively while sleeping, and when a large amount of saliva is formed inside the mouth, patients will have more difficulty in swallowing. The second one, the main consideration is that the patient has inflammation in the mucous membrane of the throat, so the patient will form a lot of saliva. It is recommended that the patient try to lie on his side while sleeping, and if there is inflammation in the mucous membrane of the throat, active symptomatic treatment is needed. Before going to bed, patients can use tablets, such as iron flute tablets or fat sea tablets, and can also spray inside the throat with open throat sword spray, which can reduce the patient’s pharyngeal cavity mucous membrane secretion. After active treatment, the patient’s symptoms will improve.
