Snoring (commonly known as whistling) is caused by vibration of muscles and soft tissues due to poor air flow through the airway. For adults, it is not very popular as it is common. Because of this, some snorers have a long sleepless night, which is a lifelong regret for them and their families. Therefore, snoring should not be considered as a localized problem of the airways, but it has a systemic effect on the human body. Today, we will talk about the injuries behind snoring. According to statistics, snoring is more serious in men, the ratio of male to female is “6 to 1”. Snoring can occur in men after the age of 20, and in women later than men, mostly after the age of 40. The causes of snoring can be categorized into central, obstructive and mixed diseases. However, for normal people, obesity is one of the most important causes of snoring. Since the airway of obese people is narrower than normal people, during the daytime when they are awake, the airway stays open when the muscles of the pharynx are contracted, and thus the airway will not be blocked. However, at night when the nerve excitability decreases during sleep, the muscle relaxation can make the pharyngeal tissues blocked, resulting in the collapse of the upper airway, when the airflow through the narrow part, it will produce vortex also caused by the vibration, so that bursts of snoring is also produced. The impact of snoring on the human body is multifaceted, highlighting the chronic damage to the heart, brain, kidneys and these important organs, especially those snorers who have sleep apnea, the medical will be habitual whistling accompanied by sleep apnea phenomenon is regarded as a pathological state and called sleep apnea syndrome (SAS). Due to the narrowing of the airway and poor airflow, these patients are often in a state of oxygen deprivation at night, which causes frequent awakening, the heaviest up to more than a hundred times a day and night, and this state continues to attack every day, which in the long run, in addition to the quality of life of the patient and the state of health causing great harm, will also cause the whole body to rise in blood pressure, accelerating the hardening of the blood vessels, which is why the incidence of cardio-cerebral and cerebral vascular diseases in the snorers is significantly higher than that of other people. This is also one of the important factors why the incidence of cardiovascular and cerebrovascular diseases in snorers is significantly higher than that of other people, and in serious cases, it can lead to a sleepless night (sudden death at night).The effect of SAS on kidneys lies in the fact that continuous hypoxia increases the acid-base regulation load of kidneys, and if the acidification function of kidneys is not adjusted correctly, it can lead to the local deposition of uric acid, calcium and other substances and the formation of stones, which is also why snorers are often combined with gout. For chronic kidney disease combined with SAS, it may increase proteinuria and accelerate renal failure. Severe snorers often open their mouths wide to whistle during sleep, and they will be woken up repeatedly due to the stoppage of breathing, and wake up looking very tired, sometimes with severe headache and so on. For SAS patients, the following tests should be performed regularly: 1. Blood gas analysis to understand the changes in the partial pressure of oxygen and carbon dioxide in arterial blood during sleep and wakefulness. 2. 2.Detection of abnormalities in the flow rate of the whistling airflow and the number and duration of whistling pauses during sleep. 3.Examination of cerebral blood vessels, except cerebral vascular substantive lesions. Therapeutic measures can be used: 1, mild cases to encourage weight loss, more exercise, improve physical fitness, avoid prolonged supine, corticosteroid nasal drops, to ensure the smoothness of the airway, if necessary, can be given oxygen therapy. 2, pharyngeal tissue relaxation, palatal prolapse, tonsillar hypertrophy leads to obstruction of the airway, feasible surgical treatment. 3.In severe SAS, home artificial mechanical ventilation can be applied to improve the breathing status.
