Often people think that people who snore in their sleep, sleep well and are very heavy, but they do not know that these people do not sleep well. Snoring is accompanied by apnea of varying length and number, and even the phenomenon of holding awake. These phenomena are mostly caused by upper airway obstruction, which can lead to lower blood oxygen level during sleep, and after a long time, the patient may end up with hypertension, stroke, diabetes, heart disease, and even sudden death at night due to multi-organ hypoxia. Therefore, snoring is a disease that cannot be ignored, especially for people with metabolic syndrome. The common features of these patients are: obesity, snoring, hyperglycemia, hypertension, hyperlipidemia, hyperviscosity, hyperuricemia, high incidence of fatty liver, and hyperinsulinemia. These individuals in particular require early medical intervention. First of all, patients are recommended to undergo tests: 1. Polysomnography (PSG), which is the most important method to diagnose sleep apnea hypoventilation syndrome (OSAHS), not only to determine the severity of the disease, but also to comprehensively assess the patient’s sleep structure, sleep apnea, hypoxia, and changes in ECG and blood pressure. In some cases it can also be differentiated from central sleep apnea syndrome with the help of esophageal pressure testing. It is not sufficient to rely solely on the symptoms described by the patient to make the diagnosis. Every patient should have at least 1 PSG test before, before and after treatment, as well as after treatment. the PSG test should be performed in a sleep respiratory laboratory with data monitoring for at least 7 h. PSG tests include EEG, electrooculogram, chin electromyogram, anterior tibial electromyogram, electrocardiogram, chest and abdominal wall respiratory movements, oral and nasal airflow, and blood oxygen saturation. 2.X-ray cephalometric measurements can be used to make a diagnosis of airway conditions at rest. 3.Nasopharyngeal fiberscopy is used for dynamic diagnosis. Next, treatment of OSAHS is divided into two categories: non-surgical treatment and surgical treatment, in addition to lateral recumbency, smoking and alcohol cessation, and weight loss in obese people. Non-surgical treatment 1, transnasal continuous positive airway pressure breathing (CPAP) This method is currently the most effective treatment for moderate to severe OSAHS, and most patients can achieve satisfactory therapeutic results through CPAP treatment. 2. Wearing oral appliance during sleep can elevate the soft palate, traction the tongue forward actively or passively, as well as jaw forward to achieve enlargement of oropharynx and hypopharynx, which is one of the main means of treating simple snoring or an important auxiliary means of non-surgical treatment of OSAHS, but it is not effective for patients with moderate to severe OSAHS. Surgical treatment The aim is to reduce and eliminate airway obstruction and prevent collapse of the soft tissues of the airway. The choice of surgical approach depends on the site of airway obstruction, its severity, the presence of morbid obesity and the general condition. The following surgical methods are commonly used: 1. tonsil and adenoidectomy; 2. nasal surgery; 3. linguoplasty; 4. palatoplasty, palatoplasty and pharyngoplasty; 5. orthognathic surgery. To sum up, snoring, especially with apnea, is a pathology. Let’s recognize it and treat it. We hope everyone has “healthy mind, good sleep”.
