Sleep apnea can be significantly reduced or even eliminated depending on what’s causing it and how severe it is. For some people, losing weight or changing sleep position is enough. For others, devices, surgery, or nerve stimulation can bring breathing events down to normal levels. The right approach depends on your severity, which is measured by how many times per hour your breathing stops or becomes shallow during sleep.
Understanding Your Severity Level
Sleep apnea severity is scored using the apnea-hypopnea index (AHI), which counts how many breathing disruptions you have per hour of sleep. Harvard Medical School classifies the ranges as follows:
- Mild: 5 to 14 events per hour
- Moderate: 15 to 29 events per hour
- Severe: 30 or more events per hour
Below 5 is considered normal. This number matters because it shapes which treatments are realistic for you. Someone with mild, positional sleep apnea has a genuine chance of eliminating it through lifestyle changes alone. Someone with severe apnea will almost certainly need a device or procedure, though lifestyle changes still help reduce severity.
Weight Loss and Lifestyle Changes
Excess weight is the single biggest modifiable risk factor for obstructive sleep apnea. Fat deposits around the upper airway narrow the space available for air, and abdominal fat pushes up on the diaphragm, reducing lung volume. Losing 10 to 15 percent of body weight can cut AHI in half for many people, and in mild cases, it can push the number below 5, effectively resolving the condition.
Alcohol makes sleep apnea worse through a specific mechanism: it relaxes the muscles in your tongue and throat, particularly the genioglossus muscle that keeps your airway open. Even moderate drinking in the evening can increase the number and duration of apnea events. Cutting out alcohol, especially within three to four hours of bedtime, is one of the simplest changes you can make. Sedatives and muscle relaxants have a similar effect and are worth discussing with your doctor if you take them regularly.
Smoking increases airway inflammation and fluid retention in the upper airway, worsening obstruction. Quitting won’t cure sleep apnea on its own, but it reduces swelling that contributes to collapse.
Positional Therapy
If your apnea is significantly worse when you sleep on your back, you may have positional obstructive sleep apnea. This is more common than many people realize. Sleeping on your back allows gravity to pull the tongue and soft tissues backward, narrowing the airway.
Wearable vibrotactile devices, which gently vibrate when you roll onto your back, have strong evidence behind them. A meta-analysis of 18 studies found these devices reduced AHI by an average of about 9 events per hour and cut the time spent sleeping on the back by 70%. Overall, they achieved a 43% reduction in AHI. For someone with mild to moderate positional apnea, that reduction can be the difference between a clinical diagnosis and normal breathing.
Low-tech options like a tennis ball sewn into the back of a sleep shirt work on the same principle, though adherence tends to drop off over time. The wearable devices are more comfortable for long-term use.
CPAP and Oral Appliances
Continuous positive airway pressure (CPAP) remains the most effective treatment across all severity levels. It works by blowing a steady stream of air through a mask to keep your airway open. When used consistently, it can reduce AHI to near zero. The challenge is tolerance: many people struggle with the mask, the noise, or the sensation of pressurized air, and stop using it.
Oral appliances, sometimes called mandibular advancement devices, are custom-fitted mouthpieces that push the lower jaw slightly forward to open the airway. A clinical crossover trial comparing the two found that CPAP was more effective at reducing AHI across mild, moderate, and severe groups. However, oral appliances still produced significant AHI reductions in all three groups, and the percentage improvement didn’t differ dramatically between severity levels. For people with mild to moderate apnea who can’t tolerate CPAP, an oral appliance is a legitimate alternative. A dentist trained in sleep medicine fits and adjusts the device.
Mouth and Throat Exercises
Myofunctional therapy involves targeted exercises for the tongue, throat, and facial muscles to strengthen the tissues that keep the airway open during sleep. The exercises typically include things like pressing the tongue against the roof of the mouth, practicing specific swallowing patterns, and doing repetitive cheek and throat movements.
A systematic review and network meta-analysis found that when daily practice exceeds 30 minutes, myofunctional therapy can significantly reduce AHI. It works best as a complement to other treatments rather than a standalone cure. Combining it with CPAP led to a greater AHI reduction than CPAP alone, though it didn’t dramatically change CPAP’s overall efficacy. The exercises also improved subjective symptoms like daytime sleepiness. If you’re looking for something you can do at home to make your other treatment work better, this is worth exploring.
Hypoglossal Nerve Stimulation
For people who cannot use or tolerate CPAP, an implanted nerve stimulator offers another option. The FDA-approved Inspire system works by delivering mild electrical stimulation to the nerve that controls tongue movement, keeping the airway open during sleep. A small device is surgically implanted in the chest, similar to a pacemaker, and you activate it with a remote control before bed.
Eligibility is specific. You need to be 22 or older (18 in some cases), have moderate to severe apnea with an AHI between 15 and 100, and have already tried and failed CPAP. One key requirement: your airway cannot have complete concentric collapse at the soft palate, because the device works by moving the tongue forward rather than opening the palate. A drug-induced sleep endoscopy is typically performed beforehand to check this. Adolescents aged 13 to 18 with Down syndrome and severe apnea also qualify under specific conditions.
Surgical Options
Several surgical procedures can permanently alter airway anatomy. The most effective is maxillomandibular advancement (MMA), which moves both the upper and lower jaw forward to enlarge the airway space behind the tongue and soft palate. According to Mayo Clinic data, more than half of patients who undergo MMA achieve complete elimination of sleep apnea, with AHI dropping below 5. The vast majority of patients, even those with severe apnea, have a successful outcome.
One common misconception is that jaw surgery only works for people with small or recessed jaws. In practice, patients with normal bone structure whose apnea comes from excess soft tissue or obesity also see good results. MMA is a significant surgery with a recovery period of several weeks, and it does change facial appearance slightly, typically moving the jawline forward. It’s generally considered when other treatments have failed or when a patient wants a more permanent solution.
Other surgical options include procedures to remove or reduce tissue in the throat, reposition the tongue base, or address nasal obstruction. These tend to have more variable success rates and are often used in combination rather than alone. Tonsil and adenoid removal is the first-line surgical treatment in children with sleep apnea, where it resolves the condition in the majority of cases.
Can Sleep Apnea Be Fully Cured?
The answer depends on what’s driving it. If your apnea is primarily caused by excess weight, significant weight loss can eliminate it entirely. If it’s caused by enlarged tonsils, removing them can be curative. Jaw surgery cures it in a substantial percentage of patients. Positional therapy can normalize AHI in people whose apnea is position-dependent.
For many adults, though, sleep apnea is a chronic condition influenced by multiple factors: anatomy, muscle tone, aging, and body composition. In these cases, the goal shifts from cure to effective long-term management. CPAP, oral appliances, and nerve stimulation don’t change your anatomy, so apnea returns when you stop using them. The most realistic path for most people is finding a treatment you’ll actually use consistently, combined with lifestyle changes that reduce severity over time.
