4 Signs You Might Have Sleep Apnea
Obstructive sleep apnea is a common disorder that causes the airways to collapse or become blocked while you’re asleep. It can cause you to stop breathing for 20 to 30 seconds at a time, numerous times throughout the night.
Untreated apnea can increase the risk of a number of diseases, including high blood pressure, heart disease, stroke, diabetes and some headache syndromes. Yet many people with sleep apnea don’t know they have it.
Could you be one of them? Alan Schwartz, M.D., director of the Sleep Disorders Center at Johns Hopkins Bayview Medical Center, describes the warning signs.
1. You’re a Noisy Sleeper
Snoring, snorting or gasping: Noisy sleep is a warning sign that your upper airway might be obstructed. Not all snorers have apnea, but the two often go hand-in-hand, Schwartz says. “As snoring gets louder, chances of having sleep apnea are greater and greater.”
If you have apnea, your bed partner might notice that the snores are punctuated by pauses in breathing. “Those are apnea episodes, and they can recur hundreds of times a night,” Schwartz says.
2. You’re Restless During Sleep
People with apnea often toss and turn and otherwise show signs of restless nighttime sleep, Schwartz notes. If you find yourself kicking, thrashing, jerking or waking up under a twisted pile of disheveled sheets, apnea might be a possible cause. “When you’re struggling to breathe at night, your sleep becomes disrupted,” Schwartz says.
3. You’re Always Tired
If you’re getting a full night of sleep but still feel tired all day, apnea might be affecting the quality of your sleep. You might nod off when reading or in front of the TV. You might be more irritable, less productive and make more mistakes at work. You might even find yourself catching more colds, since poor quality sleep can interfere with the immune system. “There are all kinds of spillovers from bad quality sleep into daytime activities,” Schwartz notes.
4. You Fit the Profile
Some people are at greater risk of obstructive sleep apnea, Schwartz says. Men are more likely to have apnea than women, though the risk for women increases after menopause. And being overweight or obese increases apnea risk markedly, he adds.
If you recognize any of these warning signs, talk to your doctor. He or she will probably recommend a sleep study. Sleep studies are done overnight in a specialized lab or, sometimes, in your own home. “The sleep study is a way to characterize the breathing patterns while you’re asleep,” he says.
