How sleep apnea is treated depends on severity and what's blocking your airway
Treatment for sleep apnea starts with the least invasive option that will work for your specific situation. For mild cases, lifestyle changes alone—weight loss, sleeping position changes, avoiding alcohol before bed—can reduce or stop breathing interruptions. For moderate to severe apnea, a CPAP machine (continuous positive airway pressure) is the most common first-line treatment; it delivers pressurized air through a mask to keep your airway open while you sleep. Surgery, dental devices, and medication are options when CPAP doesn't work, isn't tolerated, or when a specific blockage can be corrected.
Your doctor will recommend treatment based on how many times per hour your breathing stops (the apnea-hypopnea index, or AHI score), whether you have central or obstructive sleep apnea, and what's causing the blockage. The goal is to restore normal breathing during sleep and reduce the strain on your heart and oxygen levels.
Key Takeaways
- CPAP machines are the most effective and most commonly prescribed treatment for moderate to severe obstructive sleep apnea.
- Lifestyle changes like weight loss and sleeping on your side can reduce mild apnea and improve CPAP effectiveness.
- Dental devices that move the lower jaw forward are an option if you cannot tolerate CPAP or have mild to moderate apnea.
- Surgery to remove tissue blocking the airway or correct structural problems is considered when other treatments fail or when a specific anatomical cause is identified.
- Central sleep apnea (where the brain doesn't signal the muscles to breathe) is treated differently and may require adaptive servo-ventilation or other ventilation devices.
CPAP machines: how they work and what to expect
A CPAP machine is a small bedside device that connects to a mask covering your nose, mouth, or both. The machine gently pushes air into your airway at a pressure set by your sleep specialist, preventing the soft tissues in your throat from collapsing during sleep. Most machines are quiet, weigh a few pounds, and run on electricity. You wear the mask every night—or at least most nights—for the treatment to work.
The first step is a CPAP titration study, a sleep test where technicians gradually increase the air pressure while you sleep to find the lowest pressure that keeps your airway open. This pressure setting is then programmed into your machine. Many modern CPAP machines are "auto-titrating," meaning they adjust pressure automatically throughout the night as your body position and sleep stage change.
Adjustment takes time. Some people sleep well with CPAP immediately; others need two to four weeks to get used to wearing a mask and feeling air pressure. Common early complaints—mask discomfort, dry nose, feeling claustrophobic—usually improve with a different mask style, a humidifier attachment, or gradual acclimation. Your sleep doctor or a CPAP technician can troubleshoot fit and comfort issues.
Dental devices and oral appliances
A mandibular advancement device (MAD) is a custom-fitted mouthpiece that gently pulls your lower jaw forward while you sleep. Moving the jaw forward opens the space behind your tongue and soft palate, reducing airway collapse. These devices work best for mild to moderate obstructive sleep apnea and are an option if you cannot tolerate CPAP, travel frequently, or prefer not to use a machine.
You will need a dentist trained in sleep medicine to fit and adjust the device. The process involves impressions of your teeth, a custom fabrication (usually taking one to two weeks), and follow-up visits to adjust how far forward the jaw is pulled. Some people experience jaw soreness or bite changes with long-term use, so your dentist will monitor this.
Dental devices are less effective than CPAP for severe apnea, but studies show they reduce the AHI score significantly in mild to moderate cases. Insurance coverage varies; some plans cover them as a CPAP alternative, while others require you to try CPAP first.
Weight loss and lifestyle modifications
Excess weight around the neck narrows the airway, making collapse more likely during sleep. Studies show that losing 10 percent of body weight can reduce the AHI score by roughly 25 to 30 percent, and larger weight loss can resolve mild apnea entirely. Weight loss works best combined with other treatments—it can reduce the pressure setting needed on your CPAP machine, for example.
Sleeping position also matters. Sleeping on your back allows gravity to pull soft tissues into your airway; sleeping on your side or stomach reduces this effect. Some people benefit from positional devices—a special pillow or a small vibrating device worn on the back that alerts you if you roll onto your back.
Avoiding alcohol and sedating medications in the hours before bed reduces muscle relaxation in the throat. Nasal congestion from allergies or a deviated septum can worsen apnea; treating the congestion with nasal steroids or saline rinses may help. These changes alone rarely cure moderate to severe apnea, but they improve outcomes when combined with CPAP or other treatments.
Surgery and structural corrections
Surgery is considered when obstructive sleep apnea is caused by a specific anatomical problem that can be corrected, or when other treatments have failed. Common procedures include uvulopalatopharyngoplasty (UPPP), which removes excess tissue from the soft palate and throat; septoplasty, which straightens a deviated nasal septum; and genioglossus advancement, which moves the tongue attachment forward to enlarge the airway.
Your sleep specialist and an ear, nose, and throat (ENT) surgeon will work together to determine whether surgery is appropriate. Success rates vary by procedure and by individual anatomy. UPPP, for example, reduces the AHI score by at least 50 percent in roughly 40 to 60 percent of patients, but does not cure apnea in most cases. Surgery carries risks including infection, bleeding, and changes to voice or swallowing, so it is typically reserved for cases where CPAP and other options have not worked.
A newer surgical option is hypoglossal nerve stimulation, a device implanted under the collarbone that sends electrical signals to the tongue muscle, pulling it forward during sleep. This procedure is FDA-approved for moderate to severe obstructive sleep apnea in people who cannot tolerate CPAP. It requires surgery to implant the device and a learning period to adjust the settings.
Treatment for central sleep apnea
Central sleep apnea occurs when the brain fails to send the signal to breathe, rather than when the airway is blocked. Standard CPAP does not work for central apnea because the problem is not airway collapse. Instead, treatment focuses on devices that prompt breathing or support ventilation.
Adaptive servo-ventilation (ASV) is a machine that delivers air pressure in a pattern timed to your breathing, essentially coaching your respiratory system. It works well for many people with central apnea but is not recommended for people with heart failure and reduced ejection fraction, as studies have raised safety concerns in that population. Bilevel positive airway pressure (BiPAP) and other ventilation modes may also be used depending on the cause of central apnea.
If central apnea is caused by an underlying condition—heart failure, opioid use, high altitude—treating that condition is part of the approach. Your sleep specialist will determine which device is safest and most effective for your situation.
Monitoring treatment effectiveness
Your doctor will want to know whether your treatment is working. This usually means a follow-up sleep study four to eight weeks after starting CPAP or another treatment to measure your AHI score and see how much the treatment has reduced breathing interruptions. Some sleep centers use home sleep apnea tests for follow-up, while others use in-lab studies.
Beyond the numbers, you should notice improvement in daytime symptoms: less daytime sleepiness, better focus, improved mood, and lower blood pressure. If you are not seeing these changes after several weeks, tell your doctor. It may mean the pressure setting needs adjustment, the mask fit needs work, or a different treatment approach should be tried.
Many CPAP machines now have wireless connectivity that allows your doctor to download data on how many nights you used the machine and how well it controlled your apnea. This remote monitoring helps your doctor spot problems early and adjust your treatment plan without waiting for an office visit.
Frequently Asked Questions
Can sleep apnea go away on its own?
Mild sleep apnea may improve with weight loss or positional changes, but moderate to severe apnea does not resolve without treatment. Untreated apnea tends to stay the same or worsen over time, especially if weight increases or age-related changes occur in the airway.
What if I cannot tolerate CPAP?
Dental devices, positional therapy, and weight loss are alternatives. If those do not work, your doctor may try BiPAP (which feels less forceful), a different mask style, or a CPAP machine with a ramp feature that starts at low pressure and gradually increases. Some people need to try multiple masks before finding one that fits comfortably. If CPAP truly cannot work, surgery or hypoglossal nerve stimulation may be options.
How long does it take to see results from treatment?
Many people feel less sleepy within a few days to a week of starting CPAP, though full adjustment takes two to four weeks. Weight loss results take longer—typically several weeks to months to see meaningful improvement in apnea severity. A follow-up sleep study usually happens four to eight weeks after starting treatment to measure how much your breathing has improved.
Do I have to use CPAP every night forever?
Yes, for most people. Sleep apnea is a chronic condition; stopping treatment allows breathing interruptions to return. The exception is if you lose a significant amount of weight or if a specific cause (like a medication) is removed. Your doctor can discuss whether your situation might change over time.
Can medication treat sleep apnea?
No medication cures or effectively treats obstructive sleep apnea. Some medications (like acetazolamide) may help central sleep apnea in specific situations, but they are not first-line treatment. Your doctor will focus on CPAP, dental devices, lifestyle changes, or surgery depending on your type and severity of apnea.
