How sleep apnea is treated depends on severity and what's causing the airway to collapse
Treatment for sleep apnea starts with identifying which type you have and how severe it is, because the path forward differs significantly. Mild cases often respond to lifestyle changes alone—weight loss, sleeping position adjustments, avoiding alcohol before bed. Moderate to severe cases almost always require a device or procedure. The most common treatment is CPAP therapy (continuous positive airway pressure), which uses a mask and machine to keep your airway open while you sleep. Surgery, dental devices, and newer options like implants exist but are less frequently used as first-line treatment.
Your doctor will recommend treatment based on sleep study results that show how many times per hour your breathing stops (the apnea-hypopnea index, or AHI score) and how much your oxygen drops. Someone with an AHI of 5 to 15 events per hour has mild sleep apnea; 15 to 30 is moderate; above 30 is severe. The higher the number and the lower the oxygen levels, the more urgent treatment becomes.
Key Takeaways
- CPAP machines are the most effective and most commonly prescribed treatment, but success depends on wearing the mask nightly—many people stop because of discomfort or adjustment issues.
- Lifestyle changes like weight loss, side sleeping, and avoiding alcohol can reduce apnea events, especially in mild cases, but rarely eliminate sleep apnea entirely on their own.
- Dental devices that move the lower jaw forward work for some people with mild to moderate apnea and are easier to travel with than CPAP machines.
- Surgery and implants are options when other treatments fail or are not tolerated, but they carry risks and do not work for everyone.
- Finding the right treatment often takes trial and adjustment—what works depends on your anatomy, the severity of your apnea, and what you can stick with long-term.
CPAP therapy: how it works and why adherence matters
A CPAP machine delivers pressurized air through a mask worn over your nose, your mouth and nose, or just your nostrils, depending on the mask style. The air pressure holds your airway open so it cannot collapse during sleep. You wear the mask every night, and the machine runs while you sleep. Most machines are small, quiet, and portable—about the size of a tissue box.
CPAP is highly effective: studies show it reduces apnea events by 80 to 90 percent in most people and restores oxygen levels to normal. It also reduces the risk of heart attack and stroke that untreated sleep apnea carries. The catch is that you have to actually wear it. Many people stop using CPAP within the first few months because the mask feels uncomfortable, causes skin irritation, or feels claustrophobic. Others find the air pressure uncomfortable or have trouble adjusting to sleeping with a mask on.
If standard CPAP does not work for you, your doctor can adjust the pressure settings, try a different mask style, or switch to BiPAP (bilevel positive airway pressure), which uses two pressure levels—one for breathing in and a lower one for breathing out. This feels less forceful to some people. Starting with a lower pressure and gradually increasing it, or using the machine during the day while awake to get used to it, can help with adjustment.
Dental devices for mild to moderate sleep apnea
A mandibular advancement device is a custom-fitted mouthguard that pulls your lower jaw forward slightly while you sleep. Moving the jaw forward opens the airway and prevents collapse. These devices are made by a dentist after a mold of your teeth and are worn nightly like a retainer.
Dental devices work best for people with mild to moderate sleep apnea and are less effective for severe cases. They are easier to travel with than CPAP machines and do not require electricity or a mask. Studies show they reduce apnea events by 50 to 70 percent on average—less than CPAP, but enough to help many people. Some people tolerate them better than masks because there is no air pressure sensation.
The downsides are that they can cause jaw pain or bite changes if worn long-term, they are more expensive upfront (often $1,500 to $3,000 without insurance), and they require a dentist experienced in sleep apnea to fit and adjust them properly. Insurance coverage varies; some plans cover them only after CPAP has been tried and failed.
Weight loss and lifestyle changes
Excess weight narrows the airway and increases the risk of collapse during sleep. Studies show that a 10 percent weight loss can reduce apnea events by 25 to 50 percent, and larger weight losses can eliminate sleep apnea entirely in some people. This is especially true for people whose apnea developed after weight gain.
Other lifestyle changes that can help include sleeping on your side instead of your back (side sleeping keeps the airway more open), avoiding alcohol and sedating medications in the evening (they relax the throat muscles and worsen apnea), and treating nasal congestion if you have it. Raising the head of your bed slightly can also help.
The reality is that lifestyle changes alone rarely cure moderate to severe sleep apnea, and they take time—weight loss is a months-long process. Most doctors recommend starting treatment with CPAP or another device while also working on weight loss and other changes. Once you lose weight and your apnea improves, you may be able to reduce your CPAP pressure or use it less frequently, but this requires follow-up sleep studies to confirm.
Surgery and implants for treatment-resistant cases
Uvulopalatopharyngoplasty (UPPP) is a surgical procedure that removes tissue from the back of the throat to widen the airway. It was one of the first surgical treatments for sleep apnea but is less commonly used now because results are unpredictable—it works well for some people and does not help others. Success rates range from 40 to 60 percent depending on the study.
Other surgical options include removing enlarged tonsils or adenoids if they are blocking the airway, or maxillomandibular advancement, a more complex surgery that moves the upper and lower jaw forward to permanently enlarge the airway. This surgery is effective but carries risks including infection, bleeding, and changes to your bite and appearance.
A newer option is the Inspire implant, a small device placed under the skin of the chest with a wire running to the airway muscles. It senses when you are breathing and stimulates the muscles to keep the airway open. The FDA approved it in 2014 for moderate to severe obstructive sleep apnea. It requires surgery to implant and costs around $30,000 to $40,000, though insurance may cover part of it. Studies show it reduces apnea events by 70 to 80 percent in people who tolerate it, but it is not suitable for everyone and requires nightly activation with a remote control.
Treating central sleep apnea and mixed apnea
Central sleep apnea, where the brain does not send the signal to breathe, is less common than obstructive apnea and does not respond to CPAP alone. Treatment depends on the underlying cause—if it is related to heart failure, treating the heart condition may help. If it persists, doctors may use adaptive servo-ventilation (ASV), a machine that monitors your breathing and adjusts pressure automatically, or bilevel devices with a backup rate, which deliver a breath if you do not breathe on your own for a set number of seconds.
Some people have both obstructive and central apnea (mixed apnea). Treatment usually starts with CPAP or BiPAP, and if central events persist, the doctor may switch to ASV or add supplemental oxygen.
What to expect during treatment adjustment
Starting any sleep apnea treatment is not usually a one-time setup. Your doctor will schedule a follow-up sleep study after you have used your device for a few weeks to check that your apnea is controlled and adjust settings if needed. For CPAP, this may be done in a lab or at home using a portable monitor.
You should also see your doctor if you experience side effects—mask discomfort, dry mouth or nose, sinus problems, or ear pain. Most of these can be managed by changing mask style, adjusting pressure, adding humidification to the machine, or using saline rinses. It often takes several tries to find what works, and that is normal.
Long-term success depends on using your treatment consistently. People who use CPAP five or more nights per week see the most benefit. If you are struggling with adherence, tell your doctor—there are usually solutions, whether that is a different mask, a different device type, or behavioral support.
Frequently Asked Questions
Can sleep apnea go away on its own?
Sleep apnea does not typically go away without treatment, but it can improve with weight loss or other lifestyle changes. If your apnea developed after gaining weight, losing that weight may reduce events significantly. However, the underlying anatomy that makes your airway prone to collapse usually remains, so most people need ongoing treatment.
How long does it take to feel better after starting treatment?
Many people notice improvement in daytime sleepiness within days to a week of starting CPAP, though some take longer to adjust. Better sleep quality, improved mood, and sharper thinking often follow within two to four weeks as your oxygen levels normalize and you get deeper sleep. Blood pressure and heart rate improvements take longer—weeks to months.
What if CPAP does not work for me?
If CPAP is not working, your doctor will first check whether the pressure settings are correct and whether you are using it consistently. If the problem is discomfort or adjustment, trying a different mask style, BiPAP, or a gradual adjustment period often helps. If CPAP truly does not work, dental devices, Inspire implants, or surgery are alternatives worth discussing with your doctor.
Do I have to use treatment forever?
Most people with sleep apnea need ongoing treatment because the condition does not cure itself. However, if you lose significant weight or if your apnea was caused by a reversible factor like enlarged tonsils, your doctor may recommend a repeat sleep study to see whether you still need treatment at the same level or can reduce it.
Can I use my CPAP machine while traveling?
Yes. CPAP machines are portable and run on standard electricity, so you can use them anywhere you have power. Many people travel with their machines. If you fly, you can bring it in carry-on luggage. Some machines are smaller and lighter than others, so ask your doctor about travel-friendly options if you travel frequently.
