Do I Have Sleep Apnea? How to Tell, and What to Do Next

Last reviewed: August 2026

Signs You Can Check Yourself

Sleep apnea hides because it happens while you are unconscious. Most people find out because someone else tells them, or because the daytime symptoms finally get bad enough to ask about. Split the signs into two groups: what happens at night, and what happens the next day.

At night (usually reported by a bed partner)

• Loud, chronic snoring that carries through a closed door
• Pauses in breathing, then a gasp, snort, or choke
• Waking up suddenly, sometimes short of breath
• Restless, thrashing sleep and frequent trips to the bathroom
• Waking with a dry mouth or sore throat from mouth breathing

The next day

• Sleepiness that a full night in bed does not fix — the single most telling daytime sign
• Morning headaches, especially a dull one at the front of the head
• Trouble concentrating, forgetfulness, a short fuse
• Nodding off while reading, watching TV, in a meeting, or at a red light
• Low mood or low interest in things you normally enjoy

Sleeping alone makes this harder to spot. If nobody can tell you what happens at night, work off the daytime list, and consider recording yourself — a phone-based snore recorder will show you the pauses and the gasps.

The 60-Second Self-Check

Doctors use a short screening questionnaire called STOP-BANG to decide who should be sent for a sleep study. It is eight yes-or-no questions covering the symptoms and the physical risk factors. It does not diagnose anything, and it deliberately over-flags people, so a high score means "get tested," not "you have it."

Snoring or Sleep Apnea? How to Tell the Difference

This is the question behind most searches, and the honest answer is that the two overlap heavily. Nearly everyone with obstructive sleep apnea snores. Most people who snore do not have sleep apnea. Snoring is the sound of a partly narrowed airway; apnea is what happens when that airway closes off completely, over and over.

	Simple snoring	Possible sleep apnea
The sound	Steady, rhythmic	Loud, then silence, then a gasp or snort
Breathing	Continuous	Repeated pauses, seen or heard by a partner
How you wake	Rested enough	Groggy, headachy, dry-mouthed
Daytime	Normal energy	Sleepy no matter how long you were in bed
Blood pressure	Unrelated	Often high, sometimes hard to control
What to do	Address the snoring directly	Get a sleep test before anything else

If your column is the left one, start with the causes of snoring and what actually helps. If anything in the right column sounds like you, get tested first. Treating apnea as if it were ordinary snoring is the mistake that costs people years.

Who Is Most at Risk

Obstructive sleep apnea comes down to airway anatomy and how much that airway relaxes when you sleep. The strongest risk factors:

• Excess weight. Fat around the neck and upper airway narrows it and makes it easier to collapse. It is the single largest modifiable factor. More on sleep apnea and weight.
• Neck circumference. Over 17 inches in men, over 16 inches in women.
• Being male. Men are diagnosed more often, though apnea in women is widely underreported and often missed because the symptoms present as fatigue, insomnia, or low mood rather than classic snoring.
• Age over 50. Throat muscle tone declines with age.
• Jaw and airway shape. A recessed lower jaw (retrognathia), a large tongue, a narrow palate, or a deviated septum.
• Enlarged tonsils or adenoids. The leading cause in children, and still relevant in adults.
• Alcohol and sedatives before bed. Both relax throat muscles and make collapse more likely. Diet plays a role too — see how diet affects sleep apnea.
• Smoking and chronic congestion. Both inflame and narrow the upper airway.

Menopause raises risk in women. So do hypothyroidism and a family history of apnea. None of these confirm anything on their own — they raise the odds enough to justify a test.

How Sleep Apnea Is Diagnosed

Diagnosis is more straightforward than most people expect, and in many cases it never involves a hospital.

1. The conversation

Your doctor asks about your sleep, your daytime energy, and your bed partner's observations, then looks at your neck, jaw, nose, and throat. A STOP-BANG or Epworth Sleepiness Scale score usually gets recorded here. Many primary care doctors can order a test at this point without a specialist referral.

2. Home sleep apnea test

A small kit is mailed to you or given to you at the office. You wear a finger sensor, a nasal cannula, and a chest band for one or two nights in your own bed. It records airflow, breathing effort, blood oxygen, and heart rate. It is cheaper, faster, and slept-through more easily than a lab study, and for straightforward suspected obstructive apnea it is now the standard first step. See our guide to at-home sleep apnea tests.

3. In-lab sleep study (polysomnography)

An overnight stay at a sleep center with fuller monitoring: brain waves, eye movement, muscle activity, heart rhythm, airflow, and blood oxygen. It is the more complete test and is used when a home test comes back inconclusive, when central sleep apnea is suspected, or when another sleep disorder may be in play alongside it.

4. Your result

Both tests produce an apnea-hypopnea index (AHI) — the average number of breathing interruptions per hour of sleep. Under 5 is normal. 5 to 15 is mild, 15 to 30 is moderate, and above 30 is severe. That single number drives which treatments you will be offered.

What Happens If You Ignore It

Every apnea event drops your blood oxygen and jolts your body out of deep sleep. Repeat that dozens of times an hour, every night, for years, and two things follow: you never get restorative sleep, and your cardiovascular system spends every night under strain.

Untreated obstructive sleep apnea is associated with a higher risk of high blood pressure, heart disease, atrial fibrillation, stroke, and type 2 diabetes, and with a meaningfully higher risk of car and workplace accidents from daytime sleepiness. Association is not the same as cause for every individual, but the link is consistent enough that sleep apnea is treated as a cardiovascular risk factor in its own right.

The upside is the flip side of the same coin: this is one of the more treatable chronic conditions out there, and most people feel the difference within weeks.

How Sleep Apnea Is Treated

The goal is always the same — keep the airway open through the night. How you get there depends on your AHI, your anatomy, and what you will actually stick with. A full breakdown lives on our sleep apnea treatments page.

CPAP

A mask delivers a steady stream of air that holds the airway open. It is the most effective treatment available and the first-line option for moderate and severe apnea. Its weakness is adherence: a large share of people stop using it. If that is you, tell your doctor rather than quietly giving up — mask type, pressure settings, and humidification all matter. See our roundups of CPAP machines and CPAP alternatives.

BiPAP

Two pressure levels instead of one, higher when you breathe in and lower when you breathe out. Used when CPAP is not tolerated or not enough, and in some cases of central sleep apnea.

Oral appliances

A dentist-fitted mandibular advancement device holds the lower jaw forward to keep the airway open. For mild to moderate obstructive apnea it is a recognized alternative to CPAP, and people tend to wear it more consistently. It is prescribed and titrated by a sleep physician or dentist.

Weight loss

Where excess weight is a factor, losing it reduces the fat around the airway and can lower AHI substantially. It is slow, and it works alongside other treatment rather than instead of it. Our guide to sleep apnea and obesity covers what the research actually shows.

Positional therapy

Some people only have apnea on their back. Side sleeping keeps the tongue from falling backward and can cut events significantly. More on sleep positions and breathing.

Surgery

A later option, not a first one. Procedures range from removing tonsils or excess soft palate tissue (UPPP) to jaw advancement to an implanted hypoglossal nerve stimulator. Results vary and recovery is real, so it is normally considered after other treatments have been tried.

Sleep Apnea FAQ

Can I diagnose sleep apnea at home?

You can screen for it at home, and you can now test for it at home. What you cannot do is self-diagnose from symptoms alone. A home sleep apnea test ordered by a doctor produces a real AHI result and a real diagnosis; a checklist or an app does not.

Can you have sleep apnea without snoring?

Yes, though it is less common. It happens more often in women, in people who are not overweight, and in central sleep apnea, where the pause comes from the brain not signalling properly rather than from a blocked airway. If you are exhausted every day and nobody can explain why, silent apnea is worth ruling out.

Does sleep apnea go away on its own?

Obstructive sleep apnea does not resolve by itself in adults. Significant weight loss, treating nasal obstruction, or cutting alcohol can reduce it, sometimes a lot. In children, removing enlarged tonsils and adenoids often does resolve it.

Can a mouthpiece treat sleep apnea?

A prescription oral appliance fitted by a sleep physician or dentist is an accepted treatment for mild to moderate obstructive sleep apnea. An over-the-counter anti-snoring mouthpiece, including VitalSleep, is a snoring product and is not intended to treat sleep apnea. The distinction matters — do not use one to avoid getting tested.

Is sleep apnea dangerous?

Left untreated, it is linked to high blood pressure, heart disease, stroke, type 2 diabetes, and accidents caused by daytime sleepiness. Treated, most of that risk is manageable. The danger is in the years people spend not knowing.

Can sleep apnea cause bed-wetting?

It can, in children and occasionally in adults. One explanation is that the repeated oxygen drops and arousals disrupt the hormonal signals that normally suppress urine production overnight. Frequent night-time bathroom trips are a more common adult version of the same pattern.

How much does a sleep test cost?

It varies widely by insurer and by test type, but home sleep apnea tests are typically a fraction of the cost of an in-lab study and are commonly covered when a doctor orders them for suspected obstructive apnea. Ask your insurer what it needs before you book.
