When most of us picture sleep apnea, we think of a middle-aged man snoring loudly, maybe with a CPAP mask on his nightstand. It’s an image that’s been reinforced for decades. But sleep apnea in women is far more common than anyone realized, and sometimes it looks completely different.
In fact, recent research suggests that while the male-to-female ratio was once estimated at 3:1 or even 5:1, the gap narrows substantially, especially after menopause, when prevalence can approach that of men. The problem is women are being missed. A lot.
Why Women Get Missed
The issue starts with the symptoms themselves. While men with sleep apnea typically present with classic signs like loud snoring, witnessed apneas, and daytime sleepiness, women’s symptoms are often more subtle and easily blamed on something else.
Women are more likely to report:
- Fatigue or tiredness instead of daytime sleepiness
- Insomnia and trouble staying asleep
- Morning headaches
- Depression, anxiety, or mood disturbances
- Waking up frequently during the night
These symptoms overlap heavily with stress, hormonal changes, and the classic complaints of perimenopause and menopause. That’s why many women go years without ever being asked about sleep apnea. They might leave their doctor’s office with an antidepressant prescription, a referral for anxiety, or simply be told they’re overworked, while the real culprit keeps disrupting their sleep.
To make matters worse, sleep apnea screening tools like the STOP-BANG questionnaire were designed around the “classic” male presentation. They simply don’t catch women well. In one study, only 36% of women with confirmed sleep apnea showed an abnormal score on the standard sleepiness scale.
The Hormone Connection
This isn’t random bad luck. There’s biology at work. Before menopause, women get some natural protection from estrogen and progesterone, hormones that help maintain muscle tone in the upper airway. This is why premenopausal women have less collapsible airways, smaller tongues, and shorter soft palates than men.
But during and after menopause, those hormone levels drop. The protective effect fades. Women often gain weight, including around the neck, and the risk for sleep apnea rises sharply. In fact, postmenopausal women may be up to three times more likely to develop sleep apnea compared to their premenopausal peers.
This isn’t just about sleep quality. Women with untreated sleep apnea face a higher mortality risk compared to women without the condition.
What We Look For
In our office, we know that women’s sleep apnea often looks different on a sleep study too. Many women have what’s called REM-predominant OSA; meaning their breathing issues are worse during REM sleep, which happens more in the second half of the night. If a sleep study is cut short, that critical REM period might be missed entirely.
Women also tend to have more hypopneas (partial airway blockages) than full apneas, and they often desaturate less dramatically. That can make their overall AHI score look lower than it should, even when symptoms are significant.
What to Watch For
If you’re a woman experiencing any of the symptoms we listed above, especially if you’re over 35, in perimenopause, or postmenopausal, don’t brush it off as just “getting older” or “being stressed.” And if you’re waking up unrefreshed, if your partner mentions you snore (even a little), or if you’re struggling with mood or energy, bring it up.
Untreated sleep apnea doesn’t just affect sleep. It’s linked to high blood pressure, heart disease, diabetes, and stroke. Women with sleep apnea are more likely to develop cardiovascular disease and have a higher burden of comorbidities than men with the same condition.
