One of the most dangerous of all sleep disorders-Obstructive Sleep Apnea-is a particular danger for those who are overweight and can be fatal. And by the same token,g starmoins cher, losing weight can greatly improve your chances of avoiding the disorder and the numerous medical side effects that come with it.
The medical definition of OSA is a drop in oxygenation that occurs more than five times per hour of sleep,g star moins cher, according to Eric Yan,lunette chanel pas cher, MD,g star, of Valens Medical,g star 2013, a practice dedicated to weight management,louis vuitton pas cher. This is usually caused by a collapse of the airway in the neck, and is directly affected by the amount of fat in a person’s neck,g star raw jeans.
Some of the symptoms of sleep apnea include excessive daytime sleepiness,sacs louis vuitton pas cher, feeling un-refreshed after sleep, nocturnal choking and loud snoring above 80 decibels,mercurial vapor pas cher. How loud is 80 decibels? It’s the loudness of your average toilet flush,g star raw. Sleep apnea also increases your risk for weight gain, cardiovascular disease, diabetes,www.louisvuittonpascherboutique.com, high blood pressure, depression,g star pas cher, stroke and sexual dysfunction. Similarly,mercurial nike, research shows that excess weight contributes to the cyclical development and aggravation of sleep apnea.
In the past 20 years,g star homme, the prevalence of OSA has increased at a comparable level to the increase in the average BMI (body mass index) for Americans,discount g star.
“Obesity may predispose someone to acquire OSA through accumulation of fat around the neck, resulting in increased pressure exerted from outside the airway and a propensity to upper airway collapse,chanel pas cher,” says Yan,chaussures adidas gazelle homme. “Neck circumference is the measurement most closely associated with OSA,g star pas cher, even in those with a normal BMI,discount g star.”
“Most studies reported a correlation between reduction in BMI and reduction in apnea episodes,lunettes chanel,” Yan says.
The most effective method of controlling the disorder is through the use of a continuous positive airway pressure (CPAP) device. A CPAP can be used with or without supplemental oxygen and gently blows air into the throat,g star pas cher, opening the airway and enabling breathing. There are no prescription medications to treat OSA specifically.
“Since OSA can result in severe daytime sleepiness and interfere with deep REM sleep at night, this can lead to significant impact on work performance, mood swings, (including depression), as well as declining health which can further affect both work and relationships,” says Yan.
Even for those with mild apnea, the disorder can be fatal, with 5-6 deaths per year per thousand with a mild case. For those with more severe symptoms, the death rate is 15 per thousand.
“Being overweight is a significant risk factor for OSA as the excess tissues in the airway will block airflow when the muscles relax during sleep,” says Dr. Joyce Walsleben, former head of Behavioral Sleep Medicine at New York University.
“The consequences of untreated OSA go far beyond simply leaving a person exhausted and groggy,” says Walsleben, who believes that maintaining a healthy weight is the most important factor in avoiding sleep disorders.
Patients concerned they might suffer from OSA will need to spend the night in a certified sleep lab where heart rate, respiration, blood oxygen levels, airflow and the electrical activity of the brain are monitored.
“People with OSA are chronically tired, which results in poor performance on the job,” Walsleben says. “Long apneas or deep loss of oxygen may impact the heart and start an arrhythmia (abnormal heart rhythms) which can lead to death.”
Fadi Xu, MD Pathophysiology at the Lovelace Respiratory Research Institute in Albuquerque, NM says that sleep apnea can partially be avoided by simply changing sleeping posture. But he also says that those suffering with OSA can have 20-50 apnea events per hour or more than 200 per night. This means that a person with such symptoms actually stops breathing that many times per night without ever knowing it. The fact that it can go undetected makes it a major concern for patient and doctor alike.
“The ‘apnea’ in sleep apnea refers to a breathing pause that lasts at least 10 seconds,” says Dr. Carol Ash, former medical director of the Sleep for Life Program at Somerset Medical Center in Somerville, NJ. She does not recommend at all taking prescription medication to treat the disorder. “In fact, taking sleeping medications can be fatal,” she says. “The brain knows when oxygen levels have fallen too low during an apnea and sends a signal to wake up the sleeper. If you’re medicated, you won’t wake up and get the oxygen you need to live.”articles connexes:
