In cartoons, their nasal(鼻子的)roar lifts the roof off houses. In situation com
6、edies, theres the wife who rolls her eyes at her snoring bedmate. But in reality, its not all that funny. In fact, snoring can be a nightmare for snorers and their troubled partners, who may wake up several times a night to poke, and maybe hoist loved ones onto their sides for a little relief.Risks
7、of Snoring ProblemsBut the nightly racket is more than a potential relationship strain. According to the latest research, an increasingly older and heavier population may make this condition an even greater a health risk than we previously thought. For Maggie Moss-Tucker, successful treatment for a
8、longtime snoring problem came almost by accident. One fall morning in 2005, she saw a sign at her local gym seeking snorers as volunteers for a study at Bostons Brigham you never talked about it with your doctor, “says Dr. David Rapoport, medical director of the Sleep Disorders Center at New York Un
9、iversity Medical Center. “But when it becomes very prominent or such that it wakes you up or interferes with breathing, it can be a problem.“Sleep apnea, in which the airway becomes blocked or, less often, the brain fails to properly control breathing during sleeping, can be viewed as one extreme of
10、 the snoring spectrum. Soft snoring, which is not generally considered a health hazard, would be at the other end. As the sound and persistence of a patients snoring grows, so do the health concerns. A study published in the March 1 issue of the journal Sleep found that loud snorers had a 40 percent
11、 greater risk than non-snorers of suffering from high blood pressure, 34 percent greater odds of having a heart attack and a 67 percent greater chance of having a stroke.Thats a problem given the number of noisy sleepers out there. In a recent poll by the National Sleep Foundation, about one third o
12、f US working adults reported snoring at least a few nights in the previous month. Snoring generally worsens with age so the rate is even higher among the elderly. And, contrary to common perceptions, its nearly as common in women as men. Menopause(更年期) appears to be a factor, as is weight. Being ove
13、rweight can cause thickness in the airway tube, holding back the flow of oxygen. Treatment of Snoring ProblemsYet many who regularly snore dont realize that it could be bad for their health. The research linking hypertension, cardiac problems and loud snoring is relatively new. And though awareness
14、of sleep apnea is growing, specialists say the condition is still vastly undertreated. Primary-care physicians dont routinely ask patients about the quality of their sleep though that is beginning to change and few patients think to tell their doctors that theyre snoring, unless it becomes hazardous
15、 to their partner. Sleep specialists estimate that between 12 million and 18 million Americans have some form of sleep apnea but many of them, like Moss-Tucker, remain undiagnosed for years. Research from the National Sleep Foundation indicates that only half of those with sleep apnea are being trea
16、ted. Since it is a progressive condition, says Michael Twery, director of the National Institutes of Healths National Center on Sleep Disorders Research, “The person whos affected is usually not aware of how severe the condition is.“Moss-Tucker remembers being drowsy during the day sometimes, but sh
17、e blamed it on her busy life. When researchers at the sleep lab asked if she had ever fallen asleep while driving, she laughed initially. But then she recalled long drives during which shed had to pull over every 45 minutes to take a cat nap(打盹) to avoid dozing off at the wheel. Shed also become acc
18、ustomed to taking daily 25-minute naps each afternoon. But once she was diagnosed and began using a Continuous Positive Airway Pressure (or CPAP) machine, the most common treatment for sleep apnea, she says, “My life changed.“Moss-Tucker no longer needed naps and her energy levels, mental clarity an
19、d general moods improved so much so that she cannot imagine one night without the CPAP, a machine with a mask that attaches to the nose, mouth or both, helping to force oxygen into the airway while the patient sleeps. If its used properly, it is nearly 100 percent effective. But CPAPs (or BiPaps, wh
20、ich deliver alternating levels of oxygen), which cost about $ 500 or more with the mask, can be not easy to use and the noise may be as disruptive to sleeping partners as snoring. Despite its efficiency, estimates of overall long-term usage rates remain between 50 to 70 percent.For snorers who dont
21、appear to have sleep apnea, there are other measures to avoid bad nights. They include: avoiding big meals and alcohol before bed; sleeping on ones side instead of the back; treating conditions tike allergies and colds that can cause or worsen snoring, and maintaining a healthy weight. There are als
22、o devices, which push the lower jaw forward to help keep the airway open. “They arc effective in a fair number of snoring cases,“ says NYUs Rapoport, but he cautions that they need to be custom fitted by dentist and can be expensive if not covered by insurance. Surgery on Snoring ProblemsSurgery to
23、widen the airways or improve nasal airflow is also an option, though it also may not be covered by insurance and success rates vary. UPPP, in which a surgeon removes tissue at the back of the throat, can require a hospital stay and a long recovery; its typically used for patients with moderate obstr
24、uctive sleep apnea. But other procedures can be performed under local anesthesia in a surgeons office, including laserassisted LAUP, a modification of UPPP in which the surgeon uses a laser to cut the uvula. Patients who get LAUP can generally resume their normal routine almost immediately afterward
25、, but they may require up to five treatments. Somnoplasty is another short office-based procedure: it uses low-power radiofrequency energy that reduces tile volume of the soft palate tissue (located at tile back of tile roof of the mouth) but may require more than one session. Nasal surgery may also
26、 be recommended for those with obstructions in the nose. Another treatment is file Pillar procedure, in which three tiny inserts are injected into the soft palate to offer support. Since its a newer procedure only approved by the FDA in August 2004, theres less long-term data. “Studies are showing i
27、t does work but to what extent is not really known yet.“ says Rapoport.With several options but no magic bullet, experts say its important to have a full medical examination to determine the best course of action. But as long as snoring is seen as more of a joke than a risk, even that step may be to
