Obstructive Sleep Apnea – Diagnosis and Treatment
Diagnosis
Doctors often start by asking about symptoms like loud snoring, feeling sleepy during the day, or waking up with headaches. Usually, they’ll do a physical exam next, checking the back of your throat, nose, and mouth.
They might measure your neck and waist, and they’ll look for risk factors such as high blood pressure, diabetes, heart disease, or a family history of sleep apnea.
If they suspect sleep apnea, they’ll likely send you to a sleep specialist. The specialist figures out how serious things are and what to do next.
The main way to confirm OSA is with tests that track your body while you sleep.
Sleep Study at a Sleep Center
A sleep study, or polysomnography, gives doctors the most detailed look at your sleep. You’ll usually spend the night in a sleep lab for this test.
During the study, they’ll measure a bunch of things:
| What’s Measured | Why It’s Important |
|---|---|
| Heart rate and rhythm | Checks for heart problems or risk of heart attack |
| Brain activity | Looks for other sleep disorders like narcolepsy |
| Lung movements | Shows breathing patterns and airflow |
| Blood oxygen levels | Reveals if blocked airways lower oxygen |
| Arm and leg movements | Spots restless limb movements during sleep |
The test also tracks the apnea-hypopnea index (AHI), which counts how many times your breathing stops or gets very shallow per hour.
At-Home Sleep Apnea Tests
Some people use a home sleep apnea test instead.
Home tests track fewer things, but they can still pick up pauses in breathing. Doctors usually recommend these for patients who seem likely to have moderate to severe OSA based on symptoms and risk factors.
Both types of tests help doctors figure out how sleep apnea affects your sleep and health.
Non-Surgical Treatments
Breathing Support Systems
Most people with obstructive sleep apnea use positive airway pressure machines. These devices push a steady stream of air through a mask over your nose or mouth while you sleep.
This gentle pressure keeps your airway open and helps prevent breathing pauses.
The most common type is continuous positive airway pressure (CPAP). It delivers a constant level of air pressure, set just right to keep your throat open at night.
A lot of people notice they feel less tired during the day and sleep better with CPAP. Getting used to the mask can be awkward or noisy at first, but newer machines are smaller and quieter.
You’ve got options for masks—nasal masks, nasal pillows, or full-face styles—so you can find what feels best.
Some CPAP machines offer extra features like adaptive pressure settings. For example, autotitrating positive airway pressure (APAP) adjusts air pressure through the night if your airway resistance changes.
Bilevel positive airway pressure (BPAP or BiPAP) gives different pressures when you breathe in and out, which some people find easier.
It’s important to use the device every night, even if it’s not always comfortable. If you’re having problems—maybe the mask doesn’t fit, it’s too loud, or your skin gets irritated—talk to your healthcare team.
Little tweaks or adding a humidifier can make things better. If you notice new snoring or big weight changes, let your provider know.
Table 1. Types of Positive Airway Pressure Devices
| Device Type | Description | When Used |
|---|---|---|
| CPAP | Constant air pressure | Most common, effective |
| APAP | Adjusts pressure as needed | Varying airway resistance |
| BPAP | Different pressures in & out | Trouble tolerating CPAP, special cases |
Mouthpiece Treatments
Custom dental mouthpieces are another option, especially for people with mild to moderate OSA or those who can’t use CPAP. These mouthpieces work by shifting your lower jaw forward or changing your tongue’s position, which helps keep your airway open.
You’ll need to see a dental provider trained in sleep medicine to get the right fit. These devices need to be tailored to you, and you might have to go back for adjustments.
Dental sleep medicine providers also check if your jaw is recessed or if you’ve got other dental issues, which helps them pick the right device.
Some newer gadgets use light electrical pulses on the tongue during the day. The idea is to strengthen tongue muscles so they don’t collapse during sleep.
This might help people with mild cases or just snoring, but it’s not a replacement for CPAP in moderate to severe OSA. You use it around your tongue for about 20 minutes a day, and it could take weeks to see results.
If you have a pacemaker or any electrical implant, you should avoid this therapy.

| Device Type | Function | Fit Supervised By |
|---|---|---|
| Mandibular devices | Moves lower jaw forward | Dental specialist |
| Tongue-retaining | Adjusts tongue position | Dental specialist |
| Tongue stimulation | Electrical pulses for muscle tone | Dental specialist |
Position and Lifestyle Changes
Positional therapy sometimes helps, especially if your symptoms get worse when you sleep on your back. Special pillows or wearable gadgets can prompt you to sleep on your side.
Changing your sleeping position might make a big difference, especially if you have a narrow nasal passage, a large uvula, or a thick tongue.
Losing weight, quitting smoking, and avoiding alcohol or sedatives before bed can also help. Dropping a few pounds can shrink tissue in your throat and tongue, making blockages less likely.
These changes usually work best alongside other treatments.
Combination Treatments
Sometimes, the best results come from combining therapies. For example, you might use a CPAP machine and also work on losing weight or changing your sleep position.
Dental devices can work with other treatments too, depending on what you need and what feels comfortable.
It helps to work with a team—sleep specialists, dental providers, maybe even a surgeon—to come up with a plan that fits you.
Surgical and Procedural Interventions
Removal or Adjustment of Throat Tissues
If other treatments don’t help, surgery might be the next step to open up your airway.
One common surgery is uvulopalatopharyngoplasty (UPPP), where doctors remove tissue from the back of your mouth and part of the soft palate. If your tonsils or adenoids are big and block your airway, they might remove those too.
They do this surgery in a hospital under general anesthesia.
Enlarged tonsils, a big uvula, or a thick soft palate can narrow your airway. Removing or trimming these parts can open things up, but results vary and not everyone benefits the same way.
Stimulating Upper Airway Muscles
A newer treatment stimulates the nerves that move your tongue. Surgeons implant a small device under your chest skin, and when you breathe in, it sends signals to push your tongue forward.
This helps keep your airway open at night. Doctors usually recommend this for moderate to severe OSA when CPAP or BPAP hasn’t worked.
Studies show this can reduce tiredness and make breathing more regular for many people. To qualify, you can’t have certain conditions like obesity or complete tongue blockage, and you need to have failed other treatments.
Correcting Jaw Structure
Some people get sleep apnea because of jaw problems, like a small or recessed lower jaw.
Maxillomandibular advancement surgery moves both jaws forward to make more space behind your tongue and soft palate. It’s a big surgery and usually only done if nothing else helps.
Creating a Breathing Passage in the Neck
Tracheostomy is a rare, last-resort surgery for life-threatening OSA. The surgeon creates a direct opening in your neck into the windpipe and puts in a breathing tube.
This bypasses blockages in the upper airway. It’s extremely effective but only used when all else fails.
Improving Nasal Breathing
Some surgeries target the nose. If you’ve got a deviated septum or nasal blockage, surgery can straighten the septum or remove polyps.
Clearing a narrow nasal passage can also make CPAP therapy more comfortable and effective.
Table 3. Surgical and Procedural Treatments
| Procedure | Area Targeted | Expected Outcome |
|---|---|---|
| Uvulopalatopharyngoplasty (UPPP) | Soft palate, uvula | Widen airway |
| Tonsillectomy/Adenoidectomy | Tonsils, adenoids | Remove blockage |
| Upper airway stimulation | Tongue muscles | Improve muscle tone |
| Maxillomandibular advancement | Jaw bones | Enlarge airway |
| Tracheostomy | Trachea | Bypass blockage |
| Nasal surgery | Nasal structures | Clear airways |
Key Considerations for Surgical Choices
Doctors usually only consider surgery or invasive procedures if nothing else works. The decision depends on what’s causing the blockage—maybe a large tongue, thick soft palate, or jaw problems.
Some people might need just one surgery, while others could need a combination, like jaw advancement and nasal work.
Summary Table: OSA Treatments and Related Features
| Treatment or Device | Targets | Used When | Notes |
|---|---|---|---|

There are so many therapies and procedures because sleep apnea has lots of causes, and everyone’s situation is a bit different.
Regular follow-ups and telling your doctor about any changes in symptoms help you and your team pick the best treatment.
Everyday Habits and Simple Remedies
You can make simple changes in your daily routine to manage obstructive sleep apnea and feel better. Shedding some extra pounds really helps, since losing weight takes pressure off your airway.
Most people notice they have more energy during the day and just feel better overall.
Try to get regular physical activity. Aim for about 150 minutes of moderate exercise a week—think walking, swimming, or cycling. Moving your body helps you lose weight, and it usually leads to better sleep at night.
Skip alcohol and certain meds, like some sleeping pills or anti-anxiety drugs. Those can relax your throat muscles and actually make your symptoms worse.
How you sleep matters, too. Lying on your back often makes airway blockages more likely. Try sleeping on your side or stomach.
Some individuals sew a tennis ball into the back of their pajamas or use pillows behind their back—sounds odd, but it keeps you from rolling over.
If you’re dealing with nasal congestion, it can make nighttime breathing tougher. Try a saline spray to clear things out. Just check with your healthcare provider before using decongestants or allergy meds for more than a few days.
Here’s a quick table with some lifestyle and home remedies:
| Change | Benefit |
|---|---|
| Lose weight | Reduces airway blockage, boosts quality of life |
| Exercise regularly | Supports weight management and sleep quality |
| Avoid alcohol & sedatives | Lessens throat muscle relaxation |
| Sleep on your side or stomach | Helps keep airway open |
| Keep nasal passages clear | Improves nighttime breathing |
Getting Ready for Your Visit
It pays to be ready before your appointment. Ask your healthcare team if they have any special instructions. Sometimes, they’ll want you to keep a sleep diary for a few days.
Write down what time you go to bed, when you wake up, and how many times you wake during the night. Jot down naps, your energy levels, and any mood changes—especially if you’re feeling irritable or down.
Write out any symptoms, even if they seem random, like waking up with headaches or feeling wiped out at work. Trouble focusing and moodiness can also point to sleep apnea.
Make a list of your health issues, any stress you’re under, or changes in your life—like new job pressures or family stuff.
Bring a full list of your medicines, vitamins, and supplements, along with how much you take and why. Don’t forget to include anything you use to help you sleep.
If you can, bring your sleep partner or at least ask them what they’ve noticed. Partners often spot loud snoring, pauses in breathing, or restless sleep. If they can’t come, just write down their observations.
Get your questions ready so you remember what to ask. Here are some ideas:
| Question Ideas for Your Doctor |
|---|
| What might be causing my sleep issues? |
| Are there tests I should take? |
| Should I visit a sleep clinic? |
| What treatments are offered? |
| How will this affect my other health problems? |
Take this list with you to the appointment.
What Your Healthcare Provider Will Ask
Your doctor or sleep specialist will ask lots of questions to get the full picture. They’ll want to know when your symptoms started and how often they happen.
Expect questions about snoring, whether it’s every night, and if anyone’s seen you stop breathing or gasp for air while sleeping.
You might get asked things like:
- Do you wake up with a dry mouth or headache?
- Is it tough to stay awake when you’re reading, watching TV, or driving?
- Do you nap during the day?
- Have you been more moody, irritable, or forgetful?
- Have things at home or work made sleep worse?
- Does anyone in your family have sleep problems?
They’ll probably ask about work performance and if tiredness has caused problems at work or school. Questions about drowsy driving come up a lot, since people with sleep apnea have a higher risk for accidents.
Just be honest and share as many details as you can. The more your healthcare provider knows, the better they can help you.
Actions to Take While Waiting for the Appointment
You can take a few simple steps before you get a diagnosis.
Try switching to side-sleeping at night. Some individuals notice that this actually eases their symptoms. Stay away from alcohol near bedtime since it can make breathing problems worse.
If you often feel sleepy during the day, avoid driving or operating machines. Daytime drowsiness makes things like driving risky, and honestly, it’s just not worth it.
If someone tells you that you look really tired, maybe take that seriously and be extra careful.
Use the time before your appointment to jot down any changes in mood, energy, or even how you’re doing at work. Keeping daily notes about your sleep and how you feel gives your doctor a much clearer picture when you finally meet.
