Your doctor will evaluate your condition based on your signs and symptoms, an examination, and tests. He or she might refer you to a sleep specialist for further evaluation.
During the physical examination, your doctor will examine the back of your throat, mouth and nose for extra tissue or abnormalities. Your doctor might measure your neck and waist circumference and check your blood pressure.
A sleep specialist can conduct additional evaluations to diagnose your condition, determine the severity of your condition and plan your treatment. The evaluation might involve staying at a sleep center overnight to monitor your breathing and other body functions as you sleep.
Tests to detect obstructive sleep apnea include:
Polysomnography. During this sleep study, you're hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep.
You might be monitored all night, or part of the night in a split-night sleep study.
In a split-night sleep study, you'll be monitored during the first half of the night. If you're diagnosed with obstructive sleep apnea, staff may wake you and give you continuous positive airway pressure for the second half of the night.
This sleep study can also help look for other sleep disorders that can cause excessive daytime sleepiness but require different treatments, such as leg movements during sleep (periodic limb movements) or sudden bouts of sleep during the day (narcolepsy).
- Home sleep apnea testing. Under certain circumstances, your doctor may provide you with an at-home version of polysomnography to diagnose obstructive sleep apnea. This test usually involves measurement of airflow, breathing patterns and blood oxygen levels, and possibly limb movements and snoring intensity.
For milder cases of obstructive sleep apnea, your doctor might recommend lifestyle changes:
- Lose weight if you're overweight.
- Exercise regularly.
- Drink alcohol moderately, if at all. Don't drink in the hours before bedtime.
- Quit smoking.
- Use a nasal decongestant or allergy medications.
- Don't sleep on your back.
- Avoid taking sedative medications such as anti-anxiety drugs or sleeping pills.
If these measures don't improve your sleep or if your apnea is moderate to severe, then your doctor may recommend other treatments. Certain devices can help open up a blocked airway. In other cases, surgery may be necessary.
Continuous positive airway pressure (CPAP)
To eliminate snoring and prevent sleep apnea, your doctor may recommend a device called a continuous positive airway pressure (CPAP) machine. A CPAP machine delivers just enough air pressure to a mask to keep your upper airway passages open, preventing snoring and sleep apnea.
An oral device is placed on the teeth and is designed to keep your throat open by holding your tongue and lower jaw forward.
Positive airway pressure. If you have obstructive sleep apnea, you may benefit from positive airway pressure. In this treatment, a machine delivers air pressure through a piece that fits into your nose or is placed over your nose and mouth while you sleep.
Positive airway pressure reduces the number of respiratory events that occur as you sleep, reduces daytime sleepiness and improves your quality of life.
The most common type is called continuous positive airway pressure, or CPAP (SEE-pap). With this treatment, the pressure of the air breathed is continuous, constant and somewhat greater than that of the surrounding air, which is just enough to keep your upper airway passages open. This air pressure prevents obstructive sleep apnea and snoring.
Although CPAP is the most consistently successful and most commonly used method of treating obstructive sleep apnea, some people find the mask cumbersome, uncomfortable or loud. However, newer machines are smaller and less noisy than older machines and there are a variety of mask designs for individual comfort.
Also, with some practice, most people learn to adjust the mask to obtain a comfortable and secure fit. You may need to try different types to find a suitable mask. Several options are available, such as nasal masks, nasal pillows or face masks.
If you're having particular difficulties tolerating pressure, some machines have special adaptive pressure functions to improve comfort. You might also benefit from using a humidifier along with your CPAP system.
CPAP may be given at a continuous (fixed) pressure or varied (autotitrating) pressure (APAP). In fixed CPAP, the pressure stays constant. In autotitrating CPAP, the levels of pressure are adjusted if the device senses increased airway resistance.
Bilevel positive airway pressure (BPAP), another type of positive airway pressure, delivers a preset amount of pressure when you breathe in and a different amount of pressure when you breathe out.
CPAP is more commonly used because it's been well studied for obstructive sleep apnea and has been shown to effectively treat obstructive sleep apnea. However, for people who have difficulty tolerating fixed CPAP, BPAP or APAP might be worth a try.
Don't stop using your positive airway pressure machine if you have problems. Check with your doctor to see what adjustments you can make to improve its comfort.
In addition, contact your doctor if you still snore despite treatment, if you begin snoring again, or if your weight goes up or down by 10% or more.
Mouthpiece (oral device). Though positive airway pressure is often an effective treatment, oral appliances are an alternative for some people with mild or moderate obstructive sleep apnea. It's also used for people with severe sleep apnea who can't use CPAP. These devices may reduce your sleepiness and improve your quality of life.
These devices are designed to keep your throat open. Some devices keep your airway open by bringing your lower jaw forward, which can sometimes relieve snoring and obstructive sleep apnea. Other devices hold your tongue in a different position.
If you and your doctor decide to explore this option, you'll need to see a dentist experienced in dental sleep medicine appliances for the fitting and follow-up therapy. A number of devices are available. Close follow-up is needed to ensure successful treatment and that use of the device doesn't cause changes to your teeth.
Surgery or other procedures
Airway stimulation system
An impulse generator is implanted in the chest and stimulates the nerve that controls tongue movements.
Upper jaw advancement
Upper jaw advancement surgery involves moving the jaw to reduce the risk of obstruction.
Surgery is usually considered only if other therapies haven't been effective or haven't been appropriate options for you. Surgical options may include:
- Surgical removal of tissue. Uvulopalatopharyngoplasty (UPPP) is a procedure in which your doctor removes tissue from the back of your mouth and top of your throat. Your tonsils and adenoids may be removed as well. UPPP usually is performed in a hospital and requires a general anesthetic.
Upper airway stimulation. This new device is approved for use in people with moderate to severe obstructive sleep apnea who can't tolerate CPAP or BPAP.
A small, thin impulse generator (hypoglossal nerve stimulator) is implanted under the skin in the upper chest. The device detects your breathing patterns and, when necessary, stimulates the nerve that controls movement of the tongue.
Studies have found that upper airway stimulation leads to significant improvement in obstructive sleep apnea symptoms and improvements in quality of life.
- Jaw surgery (maxillomandibular advancement). In this procedure, the upper and lower parts of your jaw are moved forward from the rest of your facial bones. This enlarges the space behind the tongue and soft palate, making obstruction less likely.
Surgical opening in the neck (tracheostomy). You may need this form of surgery if other treatments have failed and you have severe, life-threatening obstructive sleep apnea.
During a tracheostomy, your surgeon makes an opening in your neck and inserts a metal or plastic tube through which you breathe. Air passes in and out of your lungs, bypassing the blocked air passage in your throat.
Other types of surgery may help reduce snoring and sleep apnea by clearing or enlarging air passages, including:
- Nasal surgery to remove polyps or straighten a crooked partition between your nostrils (deviated septum)
- Surgery to remove enlarged tonsils or adenoids

Lifestyle and home remedies
In many cases, self-care may be the most appropriate way for you to deal with obstructive sleep apnea. Try these tips:
- Lose weight. If you're overweight or obese, even a moderate loss of excess weight may help relieve constriction of your airway. Losing weight can also improve your health and quality of life and might reduce your daytime sleepiness.
- Exercise. Exercising, such as aerobic exercise and strength training, can help improve your condition. Aim to exercise about 150 minutes a week, and generally try to exercise most days of the week.
- Avoid alcohol and medications such as anti-anxiety drugs and sleeping pills. Alcohol, some anti-anxiety medications, and some sleeping pills can worsen obstructive sleep apnea and sleepiness.
Sleep on your side or stomach rather than on your back. Sleeping on your back can cause your tongue and soft palate to rest against the back of your throat and block your airway.
To prevent sleeping on your back, try sewing a tennis ball in the back of your pajama top or place pillows behind you while you sleep on your side.
- Keep your nasal passages open while you sleep. If you have congestion, use a saline nasal spray to help keep your nasal passages open. Talk to your doctor about using nasal decongestants or antihistamines, because some medications may be recommended for only short-term use.
Preparing for your appointment
If you suspect that you have obstructive sleep apnea, you'll likely first see your primary care doctor. Your doctor might refer you to a sleep specialist.
Here's some information to help you get ready for your appointment.
What you can do
Be aware of pre-appointment requests. When you make your appointment, ask if there's anything you need to do in advance, such as keeping a sleep diary.
In a sleep diary, you record your sleep patterns — bedtime, number of hours slept, nighttime awakenings and awake time — as well as your daily routine, naps and how you feel during the day.
- Write down your symptoms, including any that may seem unrelated to the reason for your appointment, and when they began.
- Write down key personal information, including new or ongoing health problems, major stresses or recent life changes.
- Bring a list of all medications, vitamins or supplements you take, including doses. Include anything you've taken to help you sleep.
- Take your bed partner along, if possible. He or she can provide information about how much and how well you're sleeping. If you can't bring your partner with you, ask him or her about how well you sleep and whether you snore.
- Write down questions to ask your doctor. Preparing a list of questions can help you make the most of your time with your doctor.
For obstructive sleep apnea, some basic questions to ask your doctor include:
- What's the most likely cause of my symptoms?
- What tests do I need? Do I need to go to a sleep clinic?
- What treatments are available and which do you recommend for me?
- I have other health conditions. How can I best manage these conditions together?
Don't hesitate to ask other questions.
What to expect from your doctor
A key part of the evaluation of obstructive sleep apnea is a detailed history, meaning your doctor will ask you many questions. These may include:
- When did you first notice symptoms?
- Have your symptoms been off and on, or do you always have them?
- Do you snore? If so, does your snoring disrupt anyone else's sleep?
- Do you snore in all sleep positions or just when sleeping on your back?
- Do you ever snore, snort, gasp or choke yourself awake?
- Has anyone seen you stop breathing during sleep?
- How refreshed do you feel when you wake up? Are you tired during the day?
- Do you have a headache or dry mouth when you awaken?
- Do you doze off or have trouble staying awake while sitting quietly or driving?
- Do you nap during the day?
- Do you have family members with sleep problems?
What you can do in the meantime
- Try to sleep on your side. Most forms of obstructive sleep apnea are milder when you sleep on your side.
- Avoid drinking alcohol close to bedtime. Alcohol worsens obstructive sleep apnea.
- If you're drowsy, avoid driving. If you have obstructive sleep apnea, daytime sleepiness can put you at higher risk of motor vehicle accidents. To be safe, schedule rest breaks. If a close friend or family member ever tells you that you appear sleepier than you feel, try to avoid driving.
