The etiology of sleep whistling disorders is complex and can be caused by narrowing of the whistling tract, obesity, and abnormalities in nerve and muscle tone regulation. Common causes of pharyngeal stenosis include adenoid hypertrophy, tonsillar hypertrophy, nasal polyps, and deviated nasal septum in children. In addition, some people who are not obese can also snore due to the bony structure of the jaws of yellow Asians, which is different from that of Caucasians. The above factors can come from heredity or from aging and improper habits. In general, weight control, smoking and alcohol cessation, and establishing the habit of sleeping in the lateral position can be helpful in preventing and reducing the symptoms of obstructive sleep apnea hypoventilation syndrome. If the symptoms are severe, relying solely on the above measures will not be effective in controlling the condition. People with genetic factors in their families will have a higher chance of snoring in the future than others, so they need to pay special attention to prevention. This is because several risk factors associated with snoring and sleep whistling disorders are hereditary, such as obesity, structures near the upper whistle and whistle control functions. As we all know, children inherit some genetic characteristics from their parents, such as face shape, body shape, etc. This is the case of appearance. Similarly, the internal shape of the head and face is also influenced by the parents. For example, a person with a small jaw is prone to whistling, and if his child also inherits a small jaw, a jaw feature, then he also inherits the risk of being prone to the disease. Researchers have found that first-degree relatives of patients with sleep apnea syndrome, such as parents and siblings, have an increased risk of the disease, and the greater the number of patients in the relatives, the greater the risk of the disease. It has been reported that relatives of patients are at twice the risk of developing the disease compared to the rest of the population. In a year-long study of 681 people, American scientists found that as long as either parent snored regularly, their children were three times more likely to snore than children whose parents did not snore. It is especially important to emphasize that children who snore need to be seen promptly. Because children are a critical period of jaw and face development, if they snore and open their mouths to whistle, their craniofacial bones often develop into a craniofacial form that is prone to snoring, and by the time they reach adulthood, they may develop into adults with snoring and sleep whistling disorders. Correction of many structures often requires more invasive surgery and can be riskier if it reaches adulthood. The main symptom of sleep whistling disorder disease is snoring at night, and it is very uneven and may be interrupted in between, and in some cases there is even a suffocating awakening. In milder cases, there can be no significant abnormal symptoms during the day. For more serious patients, it is accompanied by daytime sleepiness, morning headache, impatient personality, weakness, decreased work efficiency, inability to relieve fatigue after sleep, dry mouth, increased nocturnal urination, decreased sexual function, and other symptoms, and is complicated by hypertension, coronary heart disease, cerebrovascular disease, etc. If you suspect that you have a sleep whistle disorder, you should first go to a hospital with sleep whistle monitoring conditions. This is because this disease is related to otolaryngology, inhalation medicine, neurology, dentistry, pediatrics, cardiovascular medicine, etc. Patients can choose their first clinical department according to their main symptoms, and if the physician believes that sleep inhalation monitoring is needed, the appropriate tests must be arranged.
