Sleep apnea is a common sleep disorder characterized by repeated interruptions in breathing throughout the sleep cycle.
These interruptions, called apneas, are caused by the collapse of soft tissue in the airway, which prevents oxygen from reaching the lungs.
Weak muscles in the airway, a large tongue, obesity and other factors may cause airway tissue to collapse and obstruct breathing.
You’re not alone
Obstructive sleep apnea may not only be affecting you, but also could be affecting your loved ones. Learn how sleep apnea can influence people just like you.
About 10%of the adult population in the world suffers from sleep apnea, and about 90% of them have not been diagnosed.1 7% of men are living with sleep apnea. 5% of women are living with sleep apnea. According to the American Academy of Sleep Medicine Frost and Sullivan report from 2016, approximately 12% suffer from obstructive sleep apnea, at least 29.4 million adults in the U.S. - 80% of which go undiagnosed.
That’s significant because sleep apnea is a serious condition. Sleep apnea disrupts the sleep cycle and can dramatically impact energy, mental performance and long-term health. In some cases, if left untreated, sleep apnea can be fatal.
It can be hard to take the first steps into finding out if you have sleep apnea.
Myth: I don’t think I will be comfortable sleeping in a sleep lab.
Fact: Though many people have this fear, most are able to fall asleep in the sleep lab.

Understanding your sleep study results
Your doctor ordered an overnight sleep study (also called a polysomnogram or PSG) either in a sleep center or your home, to determine if you have sleep apnea. After you complete the sleep study, your doctor will give you the results and discuss what to do next.
You may be given a copy of your sleep study report. The report is going to include information on how you slept such as: how long you slept, your Apnea Hypopnea Index (AHI) or how many times you stopped or partially stopped breathing and if your oxygen is saturated. The defining numbers of OSA are based upon your AHI. Alternatively, if your numbers fluctuate between sleeping on your side versus on your back, you may havePositional Sleep Apnea (POSA), defined as AHIsupine ≥ 2 x AHInon-supine.2
The Apnea Hypopnea Index (AHI) is the most important number on your sleep apnea test. It measures the number of times you have an apnea (when you stop breathing for short time) or a hypopnea (when you partially stop breathing for a short time) while you’re asleep. Read an example of a sleep study test result, showing AHI and other measurements used during a sleep study.
Obstructive sleep apnea is a condition in which a person stops breathing repeatedly through the night. Breathing stops because the throat or “airway” collapses and prevents air from getting into the lungs. Sleep patterns are disrupted, resulting in excessive sleepiness or fatigue during the day.
How many people in the United States have sleep apnea?
Five to 10 percent of adults in the United States have Obstructive Sleep Apnea. This is about 20 million people, and many—the majority—are yet to be diagnosed.
What causes the airway to close during sleep?
- Extra tissue in the back of the airway, such as large tonsils
- Decrease in the tone of the muscles that hold the airway open
- The tongue falling back and closing off the airway
What should you do if you think you may have sleep apnea?
Evaluation by a doctor specializing in sleep disorders is recommended. Have a sleep study done. A sleep study can provide the doctor with information about how you sleep and breathe. This information will help the doctor to determine your diagnosis and treatment options.
What are the risks of untreated sleep apnea?
Sleep apnea can have serious short- and long-term health risks if left untreated, including:
- High blood pressure
- Irregular heartbeat
- Heart disease / heart attack
- Type 2 diabetes
- Driving- and work-related accidents
What is the treatment for sleep apnea?
Most commonly, positive airway pressure (PAP) therapy is the treatment. It is noninvasive and can help with symptoms when used as prescribed. Less commonly, surgery or oral appliances are used, which may be effective in certain cases. Any treatment plan should include weight loss if needed, exercise and avoiding alcohol, sedatives and hypnotics.
How does PAP or CPAP therapy work?
CPAP (Continuous Positive Airway Pressure) provides a gentle flow of positive-pressure air through a facial mask to keep the airway open during sleep. As a result:
- Breathing becomes regular during sleep
- Snoring stops
- Restful sleep is restored
- Quality of life is improved
- Risk for high blood pressure, heart disease, heart attack, stroke and motor vehicle and work accidents are reduced
What are the nighttime symptoms of sleep apnea?
- Loud or disruptive snoring
- Witnessed pauses in breathing
- Choking or gasping for air during sleep
- Restless sleep
- Frequent visits to the bathroom
What are the daytime symptoms of sleep apnea?
- Early morning headaches
- Excessive daytime fatigue
- Poor concentration
- Depression or irritability
- Falling asleep during routine activities
