What doctors recommend depends on how severe your apnea is

Sleep apnea treatment starts with the severity of your condition and how your body responds to it. Mild cases sometimes improve with lifestyle changes alone — weight loss, sleeping on your side instead of your back, or avoiding alcohol before bed. Moderate to severe apnea almost always requires a device or procedure, because the airway collapse happens whether you change your habits or not.

Your doctor will recommend a specific path based on your sleep study results, your anatomy, and what you're willing to use every night. The most common first step is a CPAP machine (continuous positive airway pressure), which blows air into your airway to keep it open while you sleep. If CPAP doesn't work for you, other devices and surgical options exist.

Key Takeaways

  • CPAP machines are the standard first treatment for moderate to severe sleep apnea and work by delivering steady air pressure to keep your airway open.
  • If CPAP feels uncomfortable or doesn't work, alternatives include BiPAP machines, oral appliances that reposition your jaw, and positional devices.
  • Lifestyle changes like weight loss and sleeping on your side can reduce apnea severity, but rarely eliminate it on their own in moderate to severe cases.
  • Surgery is an option when other treatments fail, though success rates vary and depend on the specific anatomy causing your collapse.
  • Finding the right treatment often takes trial and adjustment — your first option may not be your final one.

How CPAP machines work and what to expect

A CPAP machine is a small bedside device that connects to a mask you wear over your nose, mouth, or both. The machine gently pressurizes the air flowing into your airway, splinting it open so it cannot collapse during sleep. You wear the mask every night — the machine turns on when you put it on and off when you remove it.

Most people notice improvement in how they feel within a few days or weeks: less daytime sleepiness, better focus, and fewer morning headaches. Your sleep partner may notice you stop snoring and gasping. The adjustment period is real, though — the mask takes getting used to, the air pressure can feel strange, and some people find the noise bothersome. Mask fit is crucial: a poor fit means air leaks, which reduces effectiveness and increases discomfort.

Your doctor will order a second sleep study after you've used CPAP for a few weeks to confirm the pressure setting is working. You'll also get follow-up appointments to check how you're tolerating the mask and whether you're using it consistently. Insurance companies often require proof of regular use — typically at least four hours per night on most nights — to keep covering the device.

BiPAP, oral appliances, and other device options

If CPAP doesn't work for you — because the mask is uncomfortable, the pressure feels intolerable, or you simply cannot adjust to wearing it — other devices can help. BiPAP machines deliver two different pressure levels: a higher pressure when you breathe in and a lower one when you breathe out, which many people find more natural and easier to tolerate than constant CPAP pressure.

Oral appliances are custom-fitted mouthpieces that gently move your lower jaw forward, which opens your airway by stretching the tissues in your throat. A dentist specializing in sleep medicine fits and adjusts these devices. They work best for mild to moderate apnea and are quieter and more portable than CPAP, but they require nightly wear and can cause jaw discomfort or bite changes over time.

Positional devices are wearable bands or vests that vibrate gently when you roll onto your back, training you to sleep on your side where your airway is less likely to collapse. These work only if your apnea is position-dependent — meaning it happens mainly when you lie on your back — and your doctor can confirm this from your sleep study.

Lifestyle changes that can reduce apnea severity

Weight loss is the most effective lifestyle change for sleep apnea. Even a 10 percent reduction in body weight can meaningfully decrease how often your airway collapses. If you are overweight, your doctor may refer you to a weight loss program or a sleep medicine specialist who can discuss realistic goals and strategies.

Sleeping on your side instead of your back reduces apnea events in some people, particularly those with mild disease. You can train yourself to side-sleep by using a body pillow, a positional device, or even a tennis ball sewn into the back of your pajamas. Avoiding alcohol in the evening helps because alcohol relaxes the throat muscles and worsens collapse.

Nasal congestion can worsen apnea by forcing you to breathe through your mouth, which narrows the airway further. If you have allergies or chronic sinus problems, treating those — with nasal sprays, antihistamines, or a humidifier — may help. Quitting smoking also improves airway function, though the benefit develops over weeks to months.

When surgery is an option

Surgery is considered when device therapy has failed or when a specific anatomical problem is identified that a surgeon can correct. The most common procedures remove or shrink excess tissue in the throat — the soft palate, uvula, or tonsils — to widen the airway. Uvulopalatopharyngoplasty (UPPP) is the traditional procedure; newer laser or radiofrequency techniques cause less pain and faster recovery.

Jaw advancement surgery moves the lower jaw forward to enlarge the airway space. This is more invasive than tissue removal and requires a longer recovery, but it can be very effective for people whose apnea is caused by a small or recessed jaw. Your surgeon will use imaging from your sleep study and CT scans to determine whether your anatomy makes you a good candidate.

Success rates for surgery vary widely — from 40 to 80 percent depending on the procedure and the individual. Some people see complete resolution; others see improvement but still need CPAP at a lower pressure. Your surgeon should discuss realistic expectations before the procedure. Surgery is not a first-line treatment because device therapy is less invasive and has fewer risks, but it can be life-changing for people who cannot tolerate or benefit from other options.

What happens after you start treatment

Your first few weeks on any treatment are about adjustment and troubleshooting. If you're using CPAP, you may need mask adjustments, pressure changes, or a switch to a different mask style. If you're using an oral appliance, your dentist will fine-tune the jaw position. Keep notes on how you're sleeping, how you feel during the day, and any discomfort, and share these with your doctor at follow-up visits.

Most insurance plans require a follow-up sleep study after three to six months of treatment to confirm that your apnea is controlled. This study shows whether your chosen treatment is actually stopping the breathing pauses. If it is not, your doctor will adjust the pressure, try a different device, or explore other options.

Long-term success depends on consistent use. CPAP works only on the nights you wear it; missing several nights a week means your apnea returns. Many people find that once they feel the benefit — better sleep, more energy, clearer thinking — motivation to use the device becomes easier. Support groups and online communities of people using the same device can help with the adjustment period.

Frequently Asked Questions

Can sleep apnea go away on its own?

Untreated sleep apnea does not resolve on its own. However, significant weight loss can reduce apnea severity enough that some people no longer need treatment. Mild apnea may improve with lifestyle changes alone, but moderate to severe apnea requires ongoing treatment because the airway collapse is structural.

How long does it take to feel better after starting CPAP?

Many people notice improvement within days — less daytime sleepiness and better focus. Others take two to four weeks to adjust to the mask and feel the full benefit. If you feel no improvement after a month of consistent use, tell your doctor; your pressure setting may need adjustment or the device may not be right for you.

What if I cannot tolerate wearing a mask every night?

Talk to your doctor about alternatives. BiPAP, oral appliances, and positional devices work for some people who cannot adjust to CPAP. You might also try different mask styles or sizes — a poor fit is often the reason people abandon CPAP. Your doctor can refer you to a CPAP specialist who helps people troubleshoot comfort issues.

Do I need to use my device forever?

Yes, unless the underlying cause of your apnea is corrected — for example, through weight loss or surgery. Sleep apnea is a chronic condition; stopping treatment means the breathing pauses return. However, your treatment needs may change over time, and your doctor can adjust your device or explore new options as your situation evolves.

Will treatment prevent the health problems sleep apnea causes?

Consistent treatment reduces your risk of heart attack, stroke, and high blood pressure. It also improves daytime function and quality of life. However, the longer your apnea went untreated before you started, the more important it is to manage other risk factors like blood pressure and cholesterol with your doctor.
