When shutting up and snoring can be caused by airway lesions, tongue root hypertrophy, excessive obesity and other factors. 1. Airway lesions: when adenoid hypertrophy, nasal polyps, severe deviation of the nasal septum, tonsil hypertrophy and other organic airway lesions, due to airway narrowing, can be shut up when the gas passes through the snoring situation. 2. Hypertrophy of tongue root: If the tongue is hypertrophied and the tongue root is hypertrophied, the tongue may fall back when sleeping in the supine position, which may block the airway and cause narrowing of the airway, and the airflow through the narrowed part will form a vortex, which will make the surrounding mucous membranes vibrate, and the snoring may occur when shutting up. 3. Excessive obesity: when the body is too obese, the pharynx and other parts of the body can be compressed by the fatty tissue, which causes airway narrowing, and when the gas passes through the narrowing place, it can cause the symptom of shutting up and snoring. When shut-up snoring occurs, you should consult a doctor in time, and under the guidance of a specialist, you can actively carry out appropriate treatment, which will help to alleviate the uncomfortable symptoms as soon as possible.
