What Can Help Sleep Apnea? Proven Treatment Options

Sleep apnea has a wide range of proven treatments, from devices worn at night to weight-loss strategies to surgery, and the best option depends on the type and severity of a person’s condition. Continuous positive airway pressure (CPAP) remains the gold standard for moderate-to-severe obstructive sleep apnea, but it is far from the only tool available. For people who cannot tolerate CPAP, or whose apnea is mild enough to respond to lighter interventions, oral appliances, positional therapy, weight loss, newer medications, and several surgical procedures all have solid evidence behind them.

CPAP and Other Positive Airway Pressure Devices

CPAP works by blowing a steady stream of pressurized air through a mask, keeping the airway open throughout the night. It is the first-line treatment for moderate and severe obstructive sleep apnea because it virtually eliminates breathing pauses when used properly. Beyond resolving apnea events themselves, consistent CPAP use is associated with a gradual reduction in diastolic blood pressure over time in people who stick with it.¹

The catch with CPAP is adherence. Many people find the mask uncomfortable, the noise annoying, or the sensation of pressurized air claustrophobic. Mask fit alone can make or break the experience; a randomized trial comparing different nasal masks found that the initial mask selection influenced both how many hours patients wore the device and how often they needed clinic visits afterward.² Working with a sleep clinic to try different masks, adjust pressure settings, and use features like heated humidification can help considerably. Researchers have also called for a multidimensional approach to improving CPAP use, combining patient education, behavioral strategies, and better device design.³ If nasal congestion is part of the problem, adding an intranasal steroid spray has been shown to improve CPAP compliance and reduce symptoms like rhinorrhea and stuffiness.⁴

Oral Appliances

Mandibular advancement devices (MADs) are custom-fitted mouthpieces that push the lower jaw slightly forward, which opens up the airway behind the tongue. For mild to moderate obstructive sleep apnea, they are considered a first-line treatment alongside CPAP.⁵ CPAP still reduces breathing events more effectively in head-to-head comparisons. In one 12-month randomized trial, CPAP cut the apnea-hypopnea index (a measure of how many breathing disruptions occur per hour) by about 18 events per hour, while a MAD cut it by about 14.⁶ But because people tend to wear oral appliances more consistently than CPAP, the real-world effectiveness gap narrows. The same trial found that patients using the MAD reported slightly better quality-of-life gains over 12 months.

Oral appliances need to be fitted by a dentist trained in sleep medicine. Over-the-counter “boil and bite” devices sold online are not equivalent and can cause jaw problems without meaningfully treating apnea. Side effects of properly fitted MADs include jaw discomfort and changes in bite alignment over time, which is why regular dental follow-up matters.

Weight Loss Through Diet and Exercise

Excess weight is the single strongest modifiable risk factor for obstructive sleep apnea. Fat deposits around the upper airway narrow the space available for airflow, and abdominal fat pushes the diaphragm upward, reducing lung volume. Losing weight directly attacks those mechanics. A systematic review and meta-analysis of randomized trials found that intensive lifestyle interventions led to an average weight loss of about 14 kilograms and a reduction of roughly 16 events per hour in the apnea-hypopnea index, with improvements lasting up to five years.⁷ A separate meta-analysis pooling both controlled and uncontrolled studies confirmed that diet-and-exercise programs produced meaningful reductions in sleep apnea severity, with the strongest benefits seen in men with moderate-to-severe disease.⁸

Weight loss is rarely a standalone cure for anything beyond mild apnea, and it takes time. But it amplifies the effectiveness of every other treatment and is the only intervention that addresses the underlying metabolic and anatomical contributors simultaneously.

GLP-1 Receptor Agonists and Tirzepatide

The newer weight-loss medications, particularly the GLP-1 receptor agonists and dual-agonist tirzepatide, have generated real excitement in sleep medicine. In two randomized, placebo-controlled trials, tirzepatide reduced the apnea-hypopnea index by 25 to 29 events per hour at one year, compared to about 5 events per hour with placebo.⁹ These are large effects, comparable to what CPAP achieves in many patients. Meta-analyses pooling data across GLP-1 agonist trials have confirmed the pattern, showing average reductions of roughly 14 to 17 events per hour along with significant weight loss and blood pressure improvements.¹⁰¹¹

These drugs are not yet standard first-line therapy for sleep apnea specifically, and they come with their own side effects, cost barriers, and questions about what happens when you stop taking them. But for patients with obesity-driven sleep apnea who struggle with CPAP and lifestyle changes alone, they represent a genuinely new option. It is worth noting that tirzepatide’s effects went beyond what you would predict from weight loss alone, suggesting the drug may also reduce fluid retention and inflammation in the airway.

Positional Therapy

In many people, apnea is substantially worse when sleeping on the back. Gravity pulls the tongue and soft tissues backward, and the airway collapses more easily in the supine position. Positional obstructive sleep apnea, where the breathing-event count at least doubles on the back compared to other positions, is common in mild-to-moderate cases. Newer positional therapy devices are small units worn on the chest or neck that vibrate gently when you roll onto your back, training you to stay on your side without waking you up.¹²

A meta-analysis of 17 studies found that these vibrotactile devices cut supine sleep time by roughly a third and reduced the apnea-hypopnea index by about 9 events per hour on average.¹³ A six-month study of one such device showed that patients achieved near-total avoidance of back sleeping and reported less daytime sleepiness and better sleep quality, with over 70% still using the device regularly at the end of the period.¹⁴ Positional therapy works best for people with mild-to-moderate positional apnea and is often used in combination with other treatments rather than alone.

Surgical Options for the Upper Airway

Surgery enters the conversation when a patient cannot tolerate CPAP or oral appliances, or when there is a clear anatomical cause, like oversized tonsils or a recessed jaw. Several procedures target different parts of the airway.

Uvulopalatopharyngoplasty

Uvulopalatopharyngoplasty (UPPP) removes excess tissue from the soft palate, uvula, and sometimes the tonsils to widen the airway at the throat level. It has been around for decades and is one of the most commonly performed sleep apnea surgeries. Outcomes are mixed. In one Mayo Clinic case series, about a quarter of patients achieved a full surgical cure, and roughly half achieved at least a 50% reduction in breathing events. Younger patients with lower body weight and less severe apnea fared better.¹⁵ A separate study found a similar success rate of about 56%, with the best outcomes predicted by lower baseline severity and fewer metabolic abnormalities.¹⁶ UPPP is not a reliable standalone cure for severe apnea, but it can reduce the CPAP pressure needed afterward or resolve mild cases entirely.

Maxillomandibular Advancement

Maxillomandibular advancement (MMA) is a more aggressive surgery that moves both the upper and lower jaw forward, physically enlarging the entire airway. It is one of the most effective surgical treatments available. A recent systematic review and meta-analysis found that MMA reduced the apnea-hypopnea index by roughly 42 events per hour on average, with significant improvements in oxygen levels and daytime sleepiness.¹⁷ Even patients with severe apnea (starting above 60 events per hour) saw large improvements, though cure rates were highest in those starting below that threshold.¹⁸ In carefully selected patients with complex airway anatomy, one study reported a 100% success rate, with postoperative results comparable to CPAP.¹⁹ MMA involves significant recovery time and changes facial appearance, so it is typically reserved for patients who have exhausted less invasive options or who have clear jaw-structure abnormalities contributing to their apnea.

Hypoglossal Nerve Stimulation

Hypoglossal nerve stimulation is a surgically implanted device, sometimes called an “upper-airway stimulator,” that senses breathing patterns and delivers mild electrical stimulation to the nerve controlling the tongue. This keeps the tongue from falling backward and blocking the airway during sleep. The device was designed specifically for patients who have difficulty accepting or sticking with CPAP.²⁰ It works best in patients without severe obesity and with a specific pattern of airway collapse, so not everyone is a candidate. For those who qualify, it has become an increasingly popular alternative to CPAP, with a growing body of long-term data supporting its safety and effectiveness.

Bariatric Surgery

When obesity is severe and lifestyle interventions have not produced enough weight loss, bariatric surgery can have profound effects on sleep apnea. A systematic review found that over 75% of bariatric surgery patients saw at least an improvement in their apnea, regardless of the specific procedure used.²¹ A prospective multicenter trial tracking patients for five years after surgery found that about 55% achieved full remission, with the average apnea-hypopnea index dropping from roughly 28 to 9 events per hour. However, moderate or severe apnea persisted in about 20% of patients even after surgery.²² Remission rates across the broader literature range from about 26% to 76% at one year, depending on the population studied and the procedure performed.²³

The key takeaway is that bariatric surgery is powerful but not a guaranteed cure. A follow-up sleep study after surgery is important, because many patients who feel dramatically better still have residual apnea that benefits from additional treatment.

Myofunctional Therapy

Myofunctional therapy is a set of exercises for the tongue, soft palate, and throat muscles, essentially physical therapy for the airway. The idea is that strengthening and toning these muscles reduces their tendency to collapse during sleep. A systematic review and meta-analysis found that these exercises reduced the apnea-hypopnea index by about 50% in adults and 62% in children, along with improvements in oxygen levels, snoring, and daytime sleepiness.²⁴ A Cochrane review confirmed that, compared to sham exercises, myofunctional therapy likely reduces daytime sleepiness and may produce a large reduction in breathing events, though the overall certainty of the evidence was rated low to moderate due to small study sizes.²⁵

This is not a standalone treatment for moderate or severe apnea, but it is noninvasive, free, and can complement other therapies. For mild cases or as an add-on to CPAP or an oral appliance, the exercises are worth discussing with a sleep specialist or speech-language pathologist trained in orofacial myology.

Avoiding Alcohol and Sedatives

Alcohol relaxes the muscles of the upper airway, which is exactly what you do not want if those muscles already collapse during sleep. A meta-analysis of 14 studies found that alcohol significantly increased breathing events during sleep and lowered blood-oxygen levels. The effect was worse in people who already snored or had a sleep apnea diagnosis, with the apnea-hypopnea index increasing by about 7 events per hour in those with existing OSA.²⁶ Sedative medications, including benzodiazepines and some sleep aids, have similar muscle-relaxing effects. Cutting back on alcohol, especially in the hours before bed, is one of the simplest things you can do to reduce apnea severity, and it costs nothing.

Treatments for Central Sleep Apnea

Central sleep apnea is a different condition from obstructive sleep apnea. Instead of a physical blockage, the brain intermittently fails to send the signal to breathe. Treatments overlap in some areas but diverge in others.

Adaptive servo-ventilation (ASV) is a specialized breathing machine that monitors breathing patterns and adjusts air pressure breath-by-breath to stabilize respiration. It effectively normalizes breathing events in central sleep apnea. However, a landmark trial found that in patients with heart failure and reduced pumping function (ejection fraction of 45% or below), ASV actually increased the risk of death from cardiovascular causes.²⁷ Clinical guidelines now recommend against using ASV in that specific population, while allowing it as an option for patients with preserved heart function or mild central apnea.²⁸ This is one of those cases where a treatment that looks effective on a sleep study can be dangerous in the wrong patient, which is why central sleep apnea should always be managed by a specialist who understands the cardiac context.

Acetazolamide, a medication originally used for altitude sickness and glaucoma, stimulates breathing by making the blood slightly more acidic. A comprehensive meta-analysis found that it reduced the apnea-hypopnea index by about 38% overall across both obstructive and central sleep apnea studies.²⁹ However, when the data were split by type, a separate meta-analysis found that the benefit was significant for central apnea but not clearly established for obstructive apnea.³⁰ The evidence remains limited and based on small, short-duration studies, so acetazolamide is generally reserved for cases where other treatments have failed or are not suitable.

Phrenic Nerve Stimulation for Central Apnea

Transvenous phrenic nerve stimulation is an implantable device that sends electrical impulses to the phrenic nerve, which controls the diaphragm. Unlike hypoglossal nerve stimulation (which targets the tongue for obstructive apnea), this device directly restores the missing breathing drive in central sleep apnea. An initial study demonstrated a 55% reduction in the apnea-hypopnea index at three months, along with improvements in oxygen levels, sleep quality, and daytime sleepiness.³¹ Five-year follow-up data showed that the benefits were sustained, with the median apnea-hypopnea index dropping from 46 events per hour at baseline to 17 at five years and the central apnea index falling from 23 to just 1.³² Some residual hypopneas remained, but the central events, which are the hallmark of the condition, were largely eliminated. This technology is still relatively new and limited to specialized centers, but for patients with central sleep apnea who cannot use ASV safely, it fills an important gap.

Sleep Apnea in Children

The treatment landscape for pediatric sleep apnea looks quite different from the adult version. Enlarged tonsils and adenoids are the most common culprit, and removal of both (adenotonsillectomy) has been the go-to treatment for decades. Success rates vary considerably, reported between 27% and 83%, depending on severity and whether the child has other contributing factors like obesity or craniofacial abnormalities.³³ A randomized crossover trial found that adenotonsillectomy accounted for the majority of improvement in the apnea-hypopnea index and produced larger increases in airway size than rapid maxillary expansion, an orthodontic technique that widens the upper jaw.³⁴ That said, both approaches are considered proven treatments for pediatric apnea, and rapid maxillary expansion can be useful when a narrow palate is contributing to the problem, especially in children whose tonsils and adenoids are not particularly enlarged.³⁵

When You Still Feel Tired Despite Treatment

Some people use CPAP faithfully, get their breathing events under control, and still feel excessively sleepy during the day. This residual excessive daytime sleepiness is a recognized condition that affects a meaningful minority of treated patients. The cause is not fully understood and may involve lasting damage to sleep-regulating brain circuits from years of untreated apnea. Pitolisant, a medication that promotes wakefulness by acting on histamine receptors in the brain, was tested in a randomized controlled trial of patients who remained sleepy despite good CPAP adherence. Sleepiness scores dropped significantly more with pitolisant than with placebo, and about 71% of patients on the drug responded to therapy.³⁶ Solriamfetol is another approved medication in this category. These drugs do not treat the apnea itself; they address the leftover sleepiness that CPAP alone does not fix. If you are compliant with your CPAP and still struggling to stay awake, it is worth bringing this up with your sleep doctor rather than assuming the treatment is not working.
