Obstructive sleep apnea is roughly two to three times more common in men than in women — a gap that narrows but doesn't close after menopause. It's also badly underdiagnosed. Best estimates suggest most men with moderate-to-severe apnea don't know they have it, and treat the daytime fatigue, morning headaches, and slowly climbing blood pressure as normal aging.
The reason this matters: untreated sleep apnea is a genuine cardiovascular risk factor, linked to hypertension, atrial fibrillation, stroke, and metabolic dysfunction. It's also treatable, often dramatically so. The gap between undiagnosed and treated is one of the higher-yield health corrections available in middle age.
Why men are more susceptible
Several anatomical and hormonal factors converge.
- Upper airway anatomy — Men have longer, more collapsible pharyngeal airways with more soft tissue that relaxes during sleep
- Fat distribution — Central and neck fat, which men accumulate more readily, physically compress the airway
- Neck circumference — Above 17 inches is a stronger predictor of apnea than BMI
- Testosterone — Modestly increases upper airway collapsibility and ventilatory instability
- Alcohol and sedative use — More common in men, and both worsen airway muscle tone during sleep
Aging compounds all of these. Muscle tone in the airway declines, weight tends to accumulate centrally, and the odds of apnea rise steeply from the forties through the sixties.
What it actually feels like
Most men don't experience apnea as "stopping breathing." They experience it as:
- Loud, disruptive snoring, often reported by a bed partner
- Waking with a dry mouth or sore throat
- Morning headaches that resolve within an hour
- Daytime sleepiness — not just tiredness but actually dozing off in low-stimulation settings
- Poor concentration or memory
- Waking to urinate two or more times per night (nocturia is under-recognized as an apnea sign)
- Blood pressure that's hard to control despite medication
- Erectile dysfunction that doesn't fit other risk factors
Bed partners often notice pauses in breathing followed by gasps or snorts. If someone has told you that, the pretest probability of apnea is high.
Getting evaluated
Home sleep tests have made diagnosis considerably easier. A primary care doctor can order one, or a sleep specialist can. The device measures airflow, oxygen saturation, and effort overnight in your own bed. In-lab polysomnography remains the gold standard and is still used when home testing is inconclusive or when other sleep disorders are suspected.
The key metric is the apnea-hypopnea index (AHI) — events per hour of sleep:
- Under 5: normal
- 5–15: mild
- 15–30: moderate
- Over 30: severe
Treatment thresholds depend on symptoms and comorbidities. Moderate or severe apnea generally warrants treatment regardless of daytime symptoms because of cardiovascular risk.
What treatment looks like
CPAP (continuous positive airway pressure) remains the most effective treatment. It splints the airway open with pressurized air through a mask. Modern machines are quieter, smaller, and better tolerated than older generations, and adherence data is remotely tracked to help troubleshoot. Well-fitted CPAP typically resolves symptoms within weeks and lowers blood pressure meaningfully.
Mandibular advancement devices — custom oral appliances that hold the jaw forward — work for mild to moderate cases and for men who cannot tolerate CPAP. Effectiveness varies by anatomy.
Weight loss genuinely helps. A 10 percent body weight reduction can drop AHI by 20 to 30 percent in overweight men. It rarely resolves severe apnea alone but often reduces required CPAP pressure.
Positional therapy matters for apnea that occurs mainly when sleeping on the back — devices and pillows that keep you on your side can meaningfully reduce events.
Hypoglossal nerve stimulation (Inspire and similar) is an option for selected patients with moderate-to-severe apnea who fail CPAP and meet anatomical criteria.
Surgery on the soft palate has fallen out of favor for most cases — results are inconsistent and often deteriorate over time.
If your bed partner has stopped sleeping in the same room because of your snoring, that is a medical sign, not a punchline.
The bottom line
Sleep apnea is more common in men, more damaging than it feels, and more treatable than most men realize. If you snore heavily, wake unrefreshed, or have hard-to-control blood pressure, ask for a home sleep test. The upside of catching it is disproportionate to the effort involved.
