Why are sleep and breathing tests required for weight loss surgery at a regular weight loss surgery center? That is because there is a very close relationship between sleep apnea syndrome and obesity. The first is that obese people his neck fat is deposited, he narrowed the mouth and neck of the upper respiratory tract, the airway is easy to collapse obstruction, so that the neck fat deposits more neck thick, it is easy to sleep apnea. Secondly, sleep apnea and obesity aggravate each other, forming a vicious circle, weight loss sleep apnea can be significantly better, but in fact, like this obese sleep apnea syndrome patients to lose weight is very difficult, and there are some patients his weight gain rate is more than the normal people obviously, so that the two are very easy to form a vicious circle, at the same time, obese patients with sleep apnea patients are prone to Lack of oxygen, sleep is not good, the brain within the control of this facility and the body metabolism produce disorders. Coupled with daytime sleepiness and less activity, consumption is naturally less, weight gain is inevitable, in turn, obesity also aggravates apnea, this vicious cycle of weeks and weeks to make the relationship between the two are close, inseparable. Obesity is an independent risk factor, more than 60% of sleep apnea syndrome prone patients obese. Obese people rock wall fat increases lead to the pharyngeal cavity volume reduction and the upper airway within the negative pressure increases, neck fat on the pharynx direct compression and obesity lead to lung function residual air volume reduction and sleep apnea syndrome easy the occurrence of related. Simple diagnostic methods: 1, the following risk factors with two: obesity, neck stubby, or have a small jaw or mandibular retraction, pharyngeal cavity narrowing, or have tonsils II degree of hypertrophy, hypertrophy of the uvula, or low nails, acromegaly, or neurological anomalies; 2, moderate-to-heavy snoring, irregular breathing at night, or breath-holding, holding awake (observation time should be not less than 15 minutes); 3, nighttime sleep rhythm disorders, in particular, frequent awakenings; 4, daytime sleep apnea syndrome is easily associated with the occurrence of sleep apnea. Frequent awakening; 4. Daytime sleepiness; 5. Typical changes in the trend graph of blood oxygen saturation monitoring, oxygen desaturation index greater than 10 times/hour. After weight loss surgery, 70% of patients with severe sleep apnea syndrome return to normal. Weight loss surgery not only sheds excess weight, but also simultaneously treats a variety of obesity-associated morbidities, such as hypertension, diabetes, fatty liver, hyperlipidemia, polycystic ovary syndrome, and cancer. If you are already suffering from the more severe form of sleep apnea syndrome, it is important that you take steps not to miss the best time for treatment.
