Sleep apnea syndrome is a disease characterized by snoring during sleep at night and sleepiness and drowsiness during the day, which involves multiple organs and systems and is very dangerous to human health. Studies have shown that nearly half of the patients with sleep apnea syndrome suffer from hypertension, and the incidence of sudden death is much higher in the group of patients with this syndrome than in the normal population. More information proves that the 5-year mortality rate of patients with untreated sleep apnea syndrome is 11% to 13%, and the 8-year mortality rate is as high as 37% for patients with more than 20 apnea episodes per hour. Multiple hazards of sleep apnea syndrome Sleep apnea syndrome causes recurrent hypoxemia at night, which can lead to the following hazards: 1, cardiovascular disease: lead to increased blood pressure, accelerated heart rate, myocardial ischemia, hypoxia, angina pectoris, myocardial infarction, arrhythmia, and even repeated cardiac arrest, and in severe cases, sudden death; 2, neurological diseases: induce cerebral infarction, leading to hemiplegia, language disorders, epilepsy, memory loss, and other diseases. 3, male diseases: inhibit androgen secretion, resulting in male sexual dysfunction; 4, traffic accidents: promote wakefulness, sleep structure disorders caused by excessive daytime sleepiness, inattention, slow reaction is very likely to cause traffic accidents, sleep apnea syndrome patients traffic accident rate is 3 to 7 times the normal population. If your body gives out the following danger signals, you should go to the hospital promptly 1. snoring, open-mouth breathing, frequent respiratory arrest during sleep; 2. repeatedly waking up from sleep, sleep restlessness, seizures; 3. sleep without relief, daytime sleepiness, drowsiness; 4. increased blood pressure after waking up from sleep; 5. memory loss, slow reaction, reduced work and learning ability; 6. angina pectoris and heart rhythm disorder during sleep; 7. Urine loss during sleep, increased nocturia; 8, headache after waking up; 9, impotence, loss of libido; 10, dementia. 1.General treatment: reduce weight, sleep on the side, avoid drinking alcohol and taking sleeping pills before sleep; 2.Oral appliance: keep the tongue from blocking the upper airway during sleep; 3.Surgery: widen the upper airway to reduce the blockage of the upper airway during sleep; 4.Positive pressure ventilation therapy: use non-invasive ventilator during sleep to provide a certain pressure of airflow to keep the upper airway open; 5.Upper airway muscle training. 5, upper airway muscle training.
