Do you wake up in the morning with a headache, feeling just as tired as when you went to sleep? Has your spouse moved to the room next door, exhausted by listening to you snore, gasp, and choke every night?
If so, you may have obstructive sleep apnea (OSA) -- a condition where the upper passages of your airway close off, interrupting your breathing and depriving you of oxygen until you wake up and start breathing again. Sleep apnea affects more than 18 million American adults.
The three main warning signs of obstructive sleep apnea are:
Should everyone who snores see a sleep specialist? No, say the experts. “Most people who snore don’t have obstructive sleep apnea, but most people who have apnea snore,” says Robert L. Owens, MD, of the Sleep Disorders Research Program at Brigham and Women’s Hospital in Boston. If you have chronic snoring that is loud enough to wake a bed partner, talk to your doctor.
Like snoring, the most definitive sign of sleep apnea -- waking up to breathe -- is often witnessed by a bed partner. People with sleep apnea frequently wake up for a few seconds to gasp for air. This can happen hundreds of times a night in people with severe sleep apnea, Owens says.
“If someone witnesses you waking up repeatedly at night, it’s very suggestive of obstructive sleep apnea,” he tells WebMD. “Increasingly, I get wives who come in with little movies on their cell phones that show what their husband looks like at night. That’s very convincing.”
If you don’t have a bed partner to catch your gasping or snoring on camera, the only signs of sleep apnea you may notice are morning headaches or extreme sleepiness during the day, says Lisa Shives, MD, medical director of Northshore Sleep Medicine in Evanston, Ill.
Sleep specialists use the Epsworth Sleepiness Scale to measure daytime sleepiness. People with extreme sleep apnea are likely to doze off in the middle of meals or conversations, Shives tells WebMD. Moderate daytime sleepiness, such as the desire to take an afternoon nap, doesn’t necessarily mean you have obstructive sleep apnea.
If you wake up with a very dry mouth and gummy front teeth, it may also be a sign of sleep apnea, Shives says. “My little phrase is, ‘It’s very hard to gasp through your nose.’ People who have obstructive sleep apnea tend to sleep with their mouths open.”
