How sleep apnea symptoms look different in women
If you picture someone living with sleep apnea, what do you see? Are they older? Are they a man? Do they snore in their sleep? Are they struggling with other health problems?
While it’s true that people who snore, are older, have other medical conditions and are male may be at risk of sleep apnea, they’re not the only ones.15,16 Sleep apnea can — and does — affect people of all ages, races, genders, shapes and sizes. Sleep apnea can affect people across a wide range of ages, body types and backgrounds.
Unfortunately, sleep apnea can be harder to spot in women, as symptoms of OSA in women may be mistaken as side effects of an ageing body or a busy lifestyle.17
According to studies, 202 million women across the globe have obstructive sleep apnea.18 However, women may not be properly diagnosed until later in life, sometimes after they go through menopause.13
Common symptoms in women
Many women believe that being tired is a normal way of life. They may chalk their exhaustion up to busy days, stressful situations or having young kids, which reduces the chance they'll report their symptoms.
Many people associate obstructive sleep apnea with loud frequent snoring that keeps you or your loved ones awake. However, women may report symptoms such as:1
- Daytime tiredness
- Insomnia
- Nightmares
- Depression
- Anxiety
Why sleep apnea is harder to diagnose in women
Typically, a diagnosis of obstructive sleep apnea begins when someone reports symptoms to their doctor. Often, a bed partner may start the process after noticing their loved one’s frequent snoring or pauses in breathing. Since the signs of sleep apnea can look different in women, they may not always recognise or report them. Instead, signs like tiredness, mood changes or trouble concentrating are sometimes mistaken for stress or depression.19
Some doctors may not recognise how sleep apnea symptoms can differ in women. Traditional screening tools were largely developed around symptoms more common in men, like snoring, so they don’t always capture the full picture when screening women with sleep apnea.1
Risk factors and women's health
In addition to challenges in diagnosing sleep apnea in women, some risk factors are unique to women.
Hormones and sleep apnea
Hormones like estrogen and progesterone are linked to lung and airway function.20 When hormone levels change, such as during a woman’s menstrual cycle, sleep quality is impacted, and sleep apnea risk may increase.21
Studies have looked at whether hormone replacement therapy might help lower sleep apnea risk in women who are in perimenopause or who have already gone through menopause. Researchers haven't reached a consensus, as there's not enough information yet, but it's an ongoing field of study in sleep apnea treatment for women.22,23
Life stages that increase risk
Some life stages unique to women can increase the risk of sleep apnea, temporarily or permanently.
Pregnancy
Pregnancy can increase the risk of obstructive sleep apnea as weight gain and fluid changes in the body cause the airway to narrow.3,24 Around 15% to 20% of women with both conditions have obstructive sleep apnea (OSA).3
Studies indicate that around 15% of pregnant women have OSA — particularly in later trimesters. Research suggests that OSA during pregnancy may be associated with a higher risk of pregnancy-related conditions, such as high blood pressure, diabetes or pre-eclampsia. OSA may also contribute to a higher likelihood of medically necessary C-sections and post-C-section wound complications.25
Pregnancy-related sleep apnea often improves after delivery. However, it can be a signal that a woman is at risk of OSA in the future.26
Menopause
During menopause, hormone changes can impact breathing functions, increasing the risk of OSA in women.27 In fact, after menopause, a woman's risks of OSA may increase to close to the risk for men.2
However, postmenopausal women may attribute sleep apnea symptoms like poor sleep quality to ageing and menopause, making sleep apnea difficult to diagnose.28
Polycystic ovary syndrome (PCOS)
Research shows that obstructive sleep apnea (OSA) affects about 37% of women with polycystic ovary syndrome (PCOS), compared to about 6% of women without PCOS. This uptick may be linked to hormone changes and a tendency to carry more weight around the belly, which can make breathing during sleep more difficult.4 PCOS may also be associated with OSA occurring at a younger age.
Physical factors
General physical factors related to how women's bodies differ from men can influence obstructive sleep apnea (OSA) risk and how the condition shows up. For example, body fat is distributed differently in women's bodies, which can impact how the airway functions.13 And on average, many women have smaller neck sizes than men, which may be related to differences in the shape and size of the airway.29 These differences may influence breathing and increase the likelihood of airway collapse or blockage.30 A smaller airway, for instance, may be more easily blocked by surrounding tissue.31
Other health conditions that often overlap
Studies indicate that women are more likely than men to have related or overlapping health conditions, which can make diagnosing sleep apnea less straightforward.1 These conditions include:
- Thyroid problems32
- Autoimmune disorders (the immune system attacks the body by mistake)33
- Fibromyalgia (a long-term condition that causes widespread pain in the body)34
- Irritable bowel syndrome (IBS) (a gut condition affecting digestion and causing belly pain)35
- Migraines36
- Depression and anxiety1
Always talk to a doctor if you are experiencing ongoing fatigue, snoring or poor sleep so you can rule out various issues and get help finding answers about your symptoms.
How sleep apnea affects women's health
Untreated sleep apnea can lead to negative health effects, including a higher risk of diabetes, stroke, heart disease and other conditions.37,38
Health risks linked to women
When it comes to heart health, women tend to have a lower risk level than men.39 However, untreated sleep apnea can raise the risk of heart conditions in women.7 It may also make it harder for the body to manage blood sugar levels, which can contribute to conditions like diabetes.6
Studies show a link between sleep apnea and mood or memory challenges in women.5 In addition, some studies suggest possible connections between untreated OSA and hormone-related conditions, such as infertility.40
Diagnosing sleep apnea in women
Because many current screening tools are geared toward symptoms more commonly seen in men with sleep apnea (like snoring) they may miss women's symptoms. It's important to look beyond these symptoms for issues like unexplained fatigue, problems sleeping and mood changes that aren't related to another condition.1
Sleep studies may help accurately diagnose sleep apnea in women.41 That’s why it’s important to talk to your doctor about your symptoms. They can help decide if a sleep study is a good idea for you and prescribe the right kind of sleep test.
Your doctor may recommend a home sleep test (HST) if you’re showing symptoms of a sleep disorder and have not been diagnosed with any other chronic medical conditions. HSTs can be conveniently completed from the comfort of your own bed, reducing the amount of time you have to wait to get tested. Your doctor may recommend an in-lab sleep test, or polysomnogram (PSG), if you have a more complex medical history and may benefit from comprehensive sleep monitoring. PSGs are usually conducted overnight in a sleep lab, where a trained lab technician can monitor your sleep.41
Sleep apnea treatment options for women
Continuous positive airway pressure (CPAP) is highly effective and is the most used and understood method for treating sleep apnea.9 CPAP therapy is a drug-free sleep apnea treatment with no medication-related side effects. When used as prescribed, CPAP therapy may help improve symptoms associated with obstructive sleep apnea 42
Oral appliances, which position the lower jaw and tongue to reduce airway blockage, may help in some cases.8 The same is true for positional therapy, which encourages a person to sleep on their side instead of on their back.43
Lifestyle approaches, including weight management, developing better sleep routines, regular exercise and stress management, can also help reduce risk factors for sleep apnea.8,44 Because numerous conditions commonly overlap in women with OSA, addressing insomnia, mood disorders and other issues alongside CPAP therapy may be beneficial.45,46
What's changing in research?
Doctors and others are learning that sleep apnea can look different in women, and new screening tools are being developed to help spot it sooner.47 This progress may help support earlier identification of OSA in women and more timely discussions about treatment options.
Treatments that take hormone changes and women's health issues into account are also increasingly recognised as important, and awareness campaigns focusing more on women's sleep health are bringing a lot of these considerations to light.1
While medical science and sleep apnea treatment continue to grow, the best thing you can do is be proactive about your own health. Talk to your doctor about your symptoms. Even if you think you're just "normally tired," a conversation with your doctor can help you understand whether you might be dealing with sleep apnea.
