“Sleep apnea is common and can seriously affect your health.”
Strong confidence. Population studies and authoritative reviews consistently show that obstructive sleep apnea is common, frequently unrecognized and associated with daytime impairment, hypertension, cardiovascular disease and crash risk. Exact prevalence depends on the definition and population.
Obstructive sleep apnea repeatedly narrows or closes the upper airway during sleep. It is common and can cause fragmented sleep, low oxygen, daytime sleepiness and important health and safety risks.
Loud snoring raises suspicion but does not diagnose sleep apnea, and some people with apnea do not report classic sleepiness. Diagnosis requires clinical evaluation and an appropriate sleep test.
Safety note: Untreated sleep apnea can contribute to dangerous daytime sleepiness and is associated with hypertension, heart disease and stroke. Do not drive or do hazardous work when struggling to stay awake.
Talk to a healthcare professional if: Promptly discuss witnessed breathing pauses, choking or gasping during sleep, resistant high blood pressure or persistent daytime sleepiness. Stop driving and seek urgent help if you cannot stay awake safely.
This is worth acting on because effective treatments exist and untreated symptoms can affect driving, blood pressure, mood and daily function.
If you snore loudly, wake gasping, have witnessed breathing pauses or remain sleepy despite enough sleep, ask a clinician whether formal sleep-apnea evaluation is appropriate.
