Sleep due to relaxation of the neck muscles, compression of the airway to narrow the airway, resulting in airflow through the narrow parts and generate vortex, inducing the emergence of snoring; 2, abdominal pressure: obese people have more fat accumulation on the stomach, the accumulation of fat leads to increased pressure on the abdomen during sleep, prone to sleep snoring phenomenon; 3, pharyngeal cavity, nasal cavity narrowing: some obese people will have tongue hypertrophy, sleep The tongue will cause the narrowing of the pharyngeal cavity, poor breathing, snoring occurs. Some patients also have nasal sinus inflammation and allergic disease factors, resulting in nasal cavity narrowing; 4, developmental malformations: when obese people have a deviated nasal septum, resulting in effective respiratory ventilation cavity becomes narrow, increasing the resistance to respiratory ventilation, sleep easily snoring, open mouth breathing performance, may also appear apnea, or even breath-holding symptoms. Snoring will not only affect the quality of sleep of others, but also affect their own health, causing repeated apnea and lack of oxygen to the blood in the brain, etc. It is recommended that obese patients adhere to exercise, pay attention to diet, and develop good habits.
