Snoring is a relatively common sleep symptom. The specific principle is like blowing a whistle, the sound made by the gas passing through different shaped objects, that is, the sound caused by the gas passing through the respiratory tract, especially the throat, pharynx and nose is called snoring. The sound and the shape of the respiratory tract, especially the shape of the nose and throat, and the size of the sound caused by each person have certain differences. For patients who are obese, have a narrow pharyngeal cavity, as well as nasal congestion and poor nose ventilation, the snoring situation should be heavier, and some can cause breathing difficulties and chronic hypoxia. If only the sound of snoring does not cause hypoxia, try to sleep in the side position, no special treatment is needed. If chronic hypoxia, especially apnea, is caused, it is recommended to go to the ENT department for timely treatment.
