Key points

✓ Witnessed breathing pauses, gasping, and frequent loud snoring may suggest sleep apnea, but snoring alone does not confirm the diagnosis.
✓ Waking unrefreshed, morning headache, difficulty concentrating, and daytime sleepiness can also be signs.
✓ Medical assessment and, when appropriate, a sleep study can confirm the condition and guide suitable treatment.

During sleep there may be repeated pauses in breathing, loud snoring, snorting, or gasping. Another person is often the first to notice them.
Frequent awakenings, unrefreshing sleep, a dry mouth, or a morning headache may also occur.
During the day, people may experience fatigue, sleepiness, irritability, memory or concentration problems, and slower reactions.
In children, sleep apnea may be associated with noisy breathing, restless sleep, hyperactivity, attention problems, or worsening asthma.

Obstructive sleep apnea occurs when the upper airway repeatedly narrows or closes during sleep; less common types require a different assessment.
Risk may increase with obesity, certain airway features, family history, age, and alcohol or sedating medicines. Enlarged tonsils or adenoids may contribute in children.
Untreated sleep apnea can affect sleep quality, blood pressure, and cardiovascular health, and can increase the risk of accidents caused by sleepiness.
Not everyone with sleep apnea has excess weight, and not everyone who snores has sleep apnea; the complete clinical history guides which tests are needed.

A clinician will review symptoms, medicines, medical history, risk factors, and observations from a bed partner when available.
A record of sleep times, awakenings, snoring, and daytime sleepiness can help describe the problem.
A sleep study, performed in a sleep center or at home depending on the situation, records breathing and other functions to confirm the type and severity.
Watches, apps, and home oximeters may provide limited information, but they do not replace medical assessment or a professionally indicated sleep study.

Seek assessment if someone notices breathing pauses, if you wake gasping, or if loud snoring occurs with persistent fatigue or daytime sleepiness.
Also seek advice if you fall asleep unintentionally, struggle to remain alert while working or driving, or notice significant changes in memory, concentration, or mood.
If you already use CPAP or another treatment, ask for review if symptoms persist, the equipment is difficult to tolerate, or your health has changed.
Treatment choice depends on the type and severity of apnea, airway anatomy, other health conditions, and the person's preferences.

Severe sleepiness or falling asleep while driving, operating machinery, or performing another hazardous task
Severe breathing difficulty, bluish lips, or inability to speak normally
Chest pain or pressure, fainting, sudden confusion, or weakness on one side of the body
A child with prolonged breathing pauses, bluish color, marked effort to breathe, or difficulty waking
Rapid deterioration, abnormal breathing while awake, or any situation that appears to be an emergency

Do not drive or perform hazardous tasks if you are severely sleepy; stop in a safe place and get help.
Do not use alcohol, sedatives, or sleeping pills to try to correct the problem without professional advice.
Do not use someone else's CPAP equipment or change prescribed pressure settings on your own.
Do not rule out apnea simply because you do not have excess weight, or confirm it only from snoring, an app, or an oximeter.

If you have symptoms, risk factors, or questions about your situation, arrange a professional medical assessment.
