If you have sleep apnea, the most important first step is getting a proper diagnosis that confirms how severe it is, because your severity level determines which treatments will work best. Sleep apnea is classified by how many times your breathing stops or becomes shallow per hour of sleep: 5 to 14 interruptions per hour is mild, 15 to 30 is moderate, and more than 30 is severe. Once you know where you fall, you can match the right combination of treatments to your situation.
Leaving sleep apnea untreated carries real consequences. It increases the risk of heart failure by 140%, stroke by 60%, and coronary heart disease by 30%. People with 15 or more breathing interruptions per hour are nearly three times more likely to develop high blood pressure. The good news is that effective treatments exist across the full severity spectrum.
Getting a Clear Diagnosis
There are two ways to confirm sleep apnea: an overnight study in a sleep clinic or a home sleep apnea test. They measure different things, and which one you need depends on your overall health.
A full overnight sleep study, called polysomnography, tracks your brain waves, eye movements, heart rhythm, blood oxygen, leg movements, breathing effort, and body position. Because it monitors brain activity, it can tell exactly when you’re asleep and precisely how many breathing disruptions happen per hour of actual sleep. This gives the most accurate severity score. An in-clinic study is the better choice if you also have heart disease, lung conditions, severe insomnia, or use opioid medications.
A home sleep apnea test is simpler. It typically monitors your breathing, blood oxygen, and chest movement using a finger sensor and elastic chest bands. It does not track brain waves, so it can’t tell how long you were actually asleep. Instead, it estimates breathing interruptions based on total recording time. For otherwise healthy people whose main concern is obstructive sleep apnea, a home test is often sufficient to get started on treatment.
CPAP Therapy: The First-Line Treatment
Continuous positive airway pressure, or CPAP, is the standard treatment for moderate to severe sleep apnea. A CPAP machine delivers a steady stream of pressurized air through a mask, keeping your airway open while you sleep. The pressure is calibrated to the lowest level that eliminates your breathing pauses, snoring, and oxygen drops. For most people, that pressure falls somewhere between 6 and 11 units, with 9 being a common middle ground.
Your pressure is determined through a titration process, either during a second overnight sleep study where a technician adjusts the pressure in real time, or through an auto-adjusting machine that finds the right range over several nights at home. A sleep specialist reviews the data and sets your final prescription.
Choosing the Right Mask
The mask matters more than most people expect. A poorly fitting mask is the top reason people abandon CPAP, so it’s worth trying different styles early on.
- Nasal pillow masks sit at the nostrils and are the least bulky option. They work well if you feel claustrophobic in larger masks, want to read or watch TV before falling asleep, or have facial hair that interferes with a seal.
- Nasal masks cover the entire nose and handle higher pressure settings better. They’re a good fit if you move around a lot in your sleep.
- Full-face masks cover both the nose and mouth. These are the right choice if you have chronic nasal congestion or breathe through your mouth at night.
- Hybrid (oral) masks deliver air through the mouth and work for mouth breathers who also want to keep their field of vision clear.
If you struggle with one type, ask for a different style before giving up on CPAP entirely. Many sleep clinics will let you trial multiple masks.
Oral Appliances for Mild to Moderate Cases
If your sleep apnea is mild or moderate, a custom-fitted oral appliance may be an alternative to CPAP. These devices look like a mouthguard and work by holding your lower jaw slightly forward, which keeps the airway from collapsing during sleep. A dentist trained in sleep medicine makes the device and adjusts it over several visits.
Oral appliances tend to work better for mild to moderate cases, though severity alone doesn’t perfectly predict who will respond. Some people with severe sleep apnea do surprisingly well with them, while some with mild cases see limited benefit. One practical advantage is adherence: studies with embedded sensors show people use oral appliances an average of 6.4 hours per night, and only about 10 to 24% stop using them. CPAP dropout rates, by comparison, can reach 50%.
Weight Loss and Its Direct Impact
For people who carry excess weight, losing it is one of the most effective things you can do. The relationship between weight loss and sleep apnea improvement is well documented and dose-dependent. A 10% reduction in BMI is associated with a 36% reduction in breathing interruptions per hour. Losing 20% of BMI corresponds to a 57% reduction, and a 30% decrease in BMI brings a 69% improvement.
The returns diminish as you lose more, meaning the first chunk of weight you lose delivers the biggest benefit per pound. Weight loss won’t necessarily cure moderate or severe sleep apnea on its own, but it can reduce severity enough to make other treatments more effective or shift you into a milder category where simpler options work.
Positional Therapy
Some people have sleep apnea that is significantly worse when they sleep on their back. If your sleep study shows this pattern, positional therapy can cut your breathing interruptions roughly in half without any other intervention.
The simplest version is the tennis ball technique: attaching a bulky object to the back of your pajamas so rolling onto your back becomes uncomfortable. More sophisticated options include small, lightweight devices worn on the chest or neck that detect when you’re on your back using built-in motion sensors and deliver a gentle vibration to prompt you to roll over. These devices are typically smaller than a matchbox and weigh under 50 grams.
In clinical studies, positional therapy devices reduced breathing interruptions by 45% to 69%, depending on the device and study. One study found that a neck-worn device dropped the median number of breathing events from 16.4 to 5.2 per hour. Positional therapy works best as a standalone treatment for mild positional sleep apnea, or as a supplement to CPAP or oral appliance therapy for more severe cases.
Surgical Options
Surgery is typically considered when CPAP and oral appliances haven’t worked or aren’t tolerated. The most common procedure removes excess tissue from the soft palate and throat to widen the airway. Results are mixed: in a Mayo Clinic review, 24% of patients achieved a full cure (fewer than 5 breathing events per hour after surgery), and about 51% achieved at least a 50% reduction in severity. That means roughly half of patients still have significant sleep apnea after the procedure.
Nerve Stimulation Implants
A newer option involves a small device implanted in the chest that stimulates the nerve controlling your tongue. During sleep, it gently pushes the tongue forward with each breath to keep the airway open. You turn it on with a remote before bed.
This treatment is designed for people with moderate to severe sleep apnea (15 to 65 events per hour) who have a BMI under 32 and have not succeeded with CPAP. Not everyone is a candidate: a brief sedated examination of the airway is needed first to check for a specific collapse pattern that makes the device ineffective. In the landmark clinical trial, 66% of patients met the success threshold at one year. Longer follow-up studies have shown success rates climbing to 74% at three years, suggesting the benefit may improve as people adjust to the device.
Building a Treatment Plan That Sticks
Most people with sleep apnea benefit from combining approaches rather than relying on a single one. Someone with moderate sleep apnea who is overweight, for example, might start CPAP for immediate relief while working on weight loss and positional changes that could reduce their reliance on the machine over time. Someone with mild positional sleep apnea might get adequate control with a chest-worn vibrating device and a 10% reduction in body weight.
Whatever combination you pursue, the key metric is your post-treatment breathing event count. Your sleep specialist can track this through CPAP data downloads, repeat home tests, or follow-up sleep studies. The goal is to get your breathing interruptions below 5 per hour, or as close to that as possible, and to resolve symptoms like daytime sleepiness and morning headaches. If your current approach isn’t getting you there, it’s worth exploring the alternatives rather than settling for partial improvement.
