Snoring is often treated as a minor annoyance, something to joke about rather than investigate. But for women over 35 — particularly during pregnancy or as perimenopause approaches — new or worsening snoring can sometimes signal sleep apnea, a condition that’s frequently underdiagnosed in women.
Understanding why hormonal and physical changes during this life stage may increase the odds of sleep apnea can help you recognize when it’s worth raising with a healthcare provider, particularly alongside other sleep architecture changes that occur with age.
What Research Shows About Sleep Apnea in Women Over 35
According to research summarized by the American Sleep Association, sleep apnea has historically been underdiagnosed in women, partly because symptoms can differ from the classic presentation more commonly described in men — loud snoring and witnessed pauses in breathing. Women are more likely to report fatigue, morning headaches, or mood changes rather than dramatic snoring, which can lead to the condition being mistaken for stress or simply “not sleeping well.” Research also indicates that both pregnancy and the hormonal shifts of perimenopause are associated with an increased risk of developing or worsening sleep apnea.
Why Pregnancy Raises the Risk
During pregnancy, weight gain, hormonal changes, and increased blood volume can all contribute to airway swelling and narrowing, particularly in the third trimester. Research published through the NIH suggests that pregnant women may be more prone to snoring and mild sleep-disordered breathing than they were before pregnancy, and in some cases this can progress to obstructive sleep apnea. This is worth monitoring since untreated sleep apnea during pregnancy has been associated with several pregnancy complications in research, making it a topic worth discussing with your OB/GYN rather than dismissing as ordinary pregnancy snoring.
Perimenopause and Sleep Apnea Risk
As estrogen and progesterone decline during perimenopause, changes in muscle tone around the airway and shifts in body fat distribution may increase susceptibility to sleep apnea. Research indicates that sleep apnea risk in women rises notably after menopause, narrowing the gap between male and female prevalence rates that exists earlier in life.
Recognizing the Symptoms
Beyond snoring, symptoms that may suggest sleep apnea include waking up gasping or choking, morning headaches, excessive daytime sleepiness despite adequate time in bed, difficulty concentrating, and mood changes. Because these symptoms overlap with general fatigue common in stress-related sleep disruption after 35, it can be easy to attribute them to something else entirely.
What a Diagnosis and Treatment Path Typically Involves
If sleep apnea is suspected, a healthcare provider may recommend a sleep study, which can sometimes be done at home with a portable monitor rather than requiring an overnight lab stay. Treatment commonly involves a CPAP (continuous positive airway pressure) device, though options vary depending on severity and individual circumstances. A sleep medicine specialist can help determine which approach fits your situation, including during pregnancy, when treatment protocols are adjusted for safety.
Frequently Asked Questions
Is snoring during pregnancy always a sign of sleep apnea?
Not necessarily — many pregnant women snore due to nasal congestion and swelling without having sleep apnea. However, loud, frequent snoring accompanied by gasping or daytime fatigue is worth mentioning to your OB/GYN.
Can perimenopause cause sleep apnea even if I’ve never snored before?
Some women develop sleep apnea for the first time during perimenopause as hormonal and airway changes occur. New snoring or unexplained fatigue during this transition is worth discussing with a healthcare provider.
Is a home sleep study accurate enough for diagnosis?
Home sleep studies can be appropriate for many people, particularly when apnea is suspected to be moderate. Your provider can advise whether a home test or in-lab study is more appropriate for your situation.
Does treating sleep apnea improve other symptoms like mood or concentration?
Many people report improvements in daytime fatigue and concentration with effective treatment, though individual results vary. A sleep specialist can discuss realistic expectations based on your specific diagnosis.
Key Takeaways
- Sleep apnea is often underdiagnosed in women because symptoms can differ from the classic snoring-and-pauses presentation.
- Both pregnancy and perimenopause are associated with an increased risk of developing or worsening sleep apnea.
- Symptoms beyond snoring include morning headaches, daytime fatigue, and difficulty concentrating.
- A sleep study, sometimes done at home, can help confirm a diagnosis, with treatment options including CPAP therapy tailored to individual needs.
