Obstructive sleep apnea syndrome can lead to sudden death at night. There are many patients who did not consider obstructive sleep apnea syndrome as a disease in the past, and think they have high blood pressure, diabetes or coronary heart disease and treat themselves with medication. If you encounter a problem, you must seek medical treatment in a timely manner and not delay treatment, the consequences of delayed treatment can even be life-threatening. Patients pause breathing at night for too long, cardiovascular accidents or arrhythmias and lead to sudden death. In addition, the poor quality of sleep at night, frequent drowsiness during the day, and increased internal or external risk factors following a decrease in quality of life are additional reasons why OSAHS is a cause of death. Obstructive sleep apnea is a disease with a high morbidity, mortality and disability rate, so it must be taken seriously.
