Major Signs and Symptoms
One of the most common signs of obstructive sleep apnea is loud and chronic (ongoing) snoring. Pauses may occur in the snoring. Choking or gasping may follow the pauses.
The snoring usually is loudest when you sleep on your back; it might be less noisy when you turn on your side. You might not snore every night. Over time, however, the snoring can happen more often and get louder.
You're asleep when the snoring or gasping happens. You likely won't know that you're having problems breathing or be able to judge how severe the problem is. A family member or bed partner often will notice these problems before you do.
Not everyone who snores has sleep apnea.
Another common sign of sleep apnea is fighting sleepiness during the day, at work, or while driving. You may find yourself rapidly falling asleep during the quiet moments of the day when you're not active. Even if you don't have daytime sleepiness, talk with your doctor if you have problems breathing during sleep.
Other Signs and Symptoms
Others signs and symptoms of sleep apnea include:
- Morning headaches
- Memory or learning problems and not being able to concentrate
- Feeling irritable, depressed, or having mood swings or personality changes
- Waking up frequently to urinate
- Dry mouth or sore throat when you wake up
In children, sleep apnea can cause hyperactivity, poor school performance, and angry or hostile behavior. Children who have sleep apnea also may breathe through their mouths instead of their noses during the day.
Sleep Apnea Research: The HeartBeat Study06/07/2012
In this video—presented by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health—Dr. Susan Redline of Harvard Medical School/Brigham and Women's Hospital discusses her ongoing sleep apnea research. Sleep apnea is a common disorder that can raise your risk for high blood pressure, heart attack, stroke, arrhythmias (irregular heartbeats), heart failure, obesity, and diabetes.
One of Dr. Redline's projects, the HeartBEAT Study, is comparing treatments for sleep apnea to see whether they lower the risk of heart disease. The results of this research, which is funded by the American Recovery and Reinvestment Act of 2009, may help reduce deaths from heart attacks and strokes.
Living With and Managing Sleep Apnea05/18/2011
This video—presented by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health—shows how Jim, the father of two young girls, has coped with having sleep apnea. Symptoms such as waking up tired and falling asleep while driving long distances made Jim concerned about his health. While Jim was sleeping, his wife noticed snoring and long periods of silence followed by gasps.
Wanting a better quality of life, Jim sought the advice of his doctor, who recommended a sleep study. As a result of the sleep study, Jim was diagnosed with severe obstructive sleep apnea and prescribed treatment with a CPAP machine. CPAP provides mild air pressure to keep the airways open during sleep.
Jim explains that adjusting to CPAP treatment was hard at first, and his inability to stick with the treatment led to more symptoms. However, after using the CPAP machine regularly, Jim feels better and has more energy to do activities with his children.
