The reason why obese people snore can be related to the narrowing of pharyngeal and nasal cavities and the accumulation of fat in the neck. 1. Pharyngeal and nasal stenosis: some fat people will have hypertrophy of the tongue, and when sleeping, the tongue will fall back and lead to narrowing of the pharyngeal cavity, resulting in breathlessness and snoring. Undifferentiated patients have nasal polyps or chronic rhinitis and allergies and other diseases caused by the narrowing of the nasal cavity, there will also be snoring. 2. Neck fat accumulation: Neck fat accumulation caused by obesity can be manifested as short and thick neck. When you sleep, the right hand neck muscle relaxes and compresses the throat area, which makes the pinch appear to decide the situation, and the airflow through the narrow mouth area appears vortex, which induces snoring. Snoring not only affects other people’s sleep can also affect their own health, causing cerebral blood hypoxia and apnea and other diseases, it is recommended that patients are advised to consult a doctor in a timely manner, to clarify the cause of the disease, and standardized treatment under the guidance of the doctor.
