Most of the general snoring can be controlled by weight reduction and side sleeping, but if it is diagnosed as snoring by doctors, the treatment should be selected individually according to different causes (such as tonsil hypertrophy, low hanging hypertrophy of soft palate, deviated nasal septum, nasal polyps, etc.) and different degrees. For example, wearing a positive pressure respirator and braces, or undergoing surgical treatment. In terms of prevention, experts recommend the following: 1, avoid smoking and alcohol, because smoking can cause aggravation of respiratory symptoms, drinking alcohol can aggravate snoring, nocturnal breathing disorders and hypoxemia, especially drinking alcohol before bedtime. 2, weight control, obesity and sleep apnea are closely linked. Randomized controlled trials have shown that a 10 kg reduction in body weight can reduce the apnea hypoventilation index by about 5 events/hour, and 63% of patients with mild disease can have their symptoms relieved, while only 13% of patients with severe obstructive sleep apnea are relieved. Although bariatric surgery can be highly effective in reducing weight, it does not necessarily eliminate apnea in the long term. Studies have shown that obstructive sleep apnea symptoms can persist or recur after surgical or non-surgical weight loss. 3, avoid sedative, sleeping drugs before bedtime, so as not to aggravate the inhibition of the central regulation of respiration. 4, to adopt a lateral sleeping position, to avoid the tongue, soft palate, uvula relaxation back during sleep and aggravate the upper airway blockage. Treatment: 1, general treatment: weight loss, more exercise, lateral sleeping position, quit smoking and alcohol, cautiously take sedative sleeping drugs, etc. 2, oral appliance treatment: wear relevant appliances in the mouth to open the airway. The disadvantage is that patients often cannot tolerate it, and the application range is narrow. 3.Non-invasive ventilation therapy: wear a nasal mask ventilator during sleep to deliver air at a certain pressure so as to eliminate snoring and apnea. The advantage is that it is non-invasive and efficient, and should be preferred especially for patients with severe diseases. The disadvantage is that it is more expensive and needs to be worn for a long time. 4.Surgical sequence treatment: including nasal reconstruction, uvula palatopharyngeal molding, hyoid suspension, chin and tongue muscle advancement and so on. The disadvantage is that the surgery is traumatic and difficult for patients to accept. 5.Minimally invasive treatment by radiofrequency ablation: It is the latest minimally invasive technology that has been generally recognized by the international medical community in recent years as an effective treatment for snoring.
