The prevalence of OSAHS is 2%-4% in the general population, with a higher incidence in men after middle age and women after menopause. The clinical manifestations of OSAHS patients are snoring during nighttime sleep with irregular snoring sounds, disturbance of breathing and sleep rhythm, recurrent apnea and awakening, or patients feeling breath-holding, increased nocturnal urination, morning headache, significant daytime sleepiness, and memory loss. There is increasing evidence that sleep apnea can lead to many complications, and current research suggests that OSAHS is the cause of hypertension, coronary heart disease, pulmonary heart disease, stroke and other cardiovascular and cerebrovascular pathologies, psychiatric disorders, sexual dysfunction and other diseases, which seriously affects people’s quality of life and health, with cardiovascular and cerebrovascular complications receiving the most attention because they are the main cause of death. If left untreated, OSAHS in children can lead to stunted growth, poor concentration, poor learning ability, cardiovascular disease and even death. Therefore, when you have the above symptoms, you should go to the hospital as soon as possible for treatment.
