Sleep apnea, now at times casually defined as having sleep frequently interrupted by pauses in breathing, had long been linked to loud snoring and daytime fatigue, often dubbed a "men's disease." Indeed, it is true that sleep apnea is most commonly diagnosed in men; but this condition certainly has far-reaching implications for women's health, too. This has led to gross underdiagnosis in women because the traditional markers used to diagnose sleep apnea among men bear little resemblance to those in women. Most patients with sleep apnea are diagnosed at an advanced stage, a process that has usually led to advanced deterioration in health. Sleep apnea is quite different in many critical aspects in women. From prevalence to symptoms, from risk factors to challenges of diagnosis, recognition, and treatment of sleep apnea in women depends on understanding these differences. Below is an examination of how sleep apnea occurs in women and why it gets missed. Further, some factors will be explored that explain why its uniqueness stands out in their health.
Prevalence and Diagnosis
Statistics on sleep apnea in women vs. men
The condition is highly more prevalent in men than women, especially as some experts assert that the likelihood of males suffering from the condition is twice as much compared to females.
According to estimates, the prevalence of the condition in women is about 3% to 5%, whereas for men, it is 10% to 17%. However, statistics are known by many to underestimate the real prevalence of sleep apnea in women, because it remains underdiagnosed and sometimes misinterpreted. Women are less diagnosed and may not be treated for sleep apnea due to its underrecognition.

Underdiagnosis in Women
The most significant issue in sleep apnea for women is its underdiagnosis.
Typically, the sleep apnea case in men is seen with snoring, pauses in breathing, and sleepiness during the day. However, women come to the physician with much more subtle or atypical symptoms. Usually, even the perceptions of the healthcare professionals, coupled with the diagnostic tools and criteria, are often not adjusted to identify this condition in women easily. Consequently, By the very fact, women's sleep apnea is frequently underestimated leading to the fact that they are diagnosed with the wrong conditions as insomnia, depression, or anxiety. The misdiagnoses contribute to the delay of real treatment regarding sleep apnea leading to the cycle of aggravating disease and deterioration of symptoms.
Causes of Underdiagnosis
Sleep apnea in women is underdiagnosed due to several reasons:
There have been fewer reports of chronic loud snoring or noteworthy events of cessation of breathing. These are two hallmark manifestations commonly linked to sleep apnea. In addition, women develop milder variants of the condition than men, thereby rendering healthcare providers' efforts to detect it quite difficult. Hormonal differences, for example, those that apply to pregnancy and menstruation, also may influence manifestations of sleep apnea, and women are not going to seek treatment for sleep apnea because they become accustomed to feeling tired or experiencing daytime somnolence. Women's healthcare providers are likely to overlook sleep apnea when women complain of fatigue, headaches, and mood disturbances. Instead, the complaints are likely to be referred to stress, depression, or hormonal changes thus failing to diagnose sleep apnea.
Most of the women without correct diagnosis and treatment are bound to suffer from severe medical conditions in their lives such as cardiovascular disorders, diabetes, and deteriorating cognitive states.
Symptoms and Presentation
Common Symptoms in Women’s
While men tend to exhibit "classic" symptoms of sleep apnea, which include very loud snoring, witnessed apneas, or pauses in breathing and daytime sleepiness, females are more likely to have atypical and mild symptoms. Women with sleep apnea will likely have:
Difficulty falling asleep or staying asleep, which is a symptom referred to as
● Insomnia
● Morning headache
● Wake up feeling tired and do not have any energy
● Mood disturbances, depression, and anxiety
● Restless legs or discomfort in the legs during nighttime
● Poor sleep fragmentation or frequent arousal during nighttime
This means that women's sleep apnea is less patent and less obvious compared to loud snoring and often occurring breathing pauses in men. This subtlety makes it tough for both women and their healthcare providers to point out to sleep apnea as the root cause of their symptoms.
Misinterpretation of Symptoms
Many women's symptoms go unnoticed or misdiagnosed with sleep apnea. It is simply attributed to fatigue due to work, family, or hormonal changes associated with a woman's menstrual cycle, pregnancy, and menopause. She may be diagnosed with insomnia, depression, or anxiety as many of the symptoms overlap, such as an inability to sleep through the night and waking up drowsy.
Further, women snore softer or even less frequently compared to men, and sleep apnea events are less likely to be identified by sleeping partners. With that in mind, sleep apnea among females may be overlooked or misdiagnosed, and women mostly end up being prescribed other medications such as those for insomnia or mood disorder instead of treatment for sleep apnea.
Risk Factors Specific to Women
Hormonal influences
Hormones play a very essential role in the development and emergence of sleep apnea in women. Some hormonal changes in a woman's life cycle increase the susceptibility to sleep apnea and also worsen the symptoms of the disease.
● Menstruation: The menstrual cycle may also influence the quality of sleep: some women, for example, do experience disturbed sleep episodes that relate to PMS or PMDD. Menstruation in and of itself is not a direct cause of sleep apnea, but changes in hormones as part of the menstrual cycle may exacerbate the nature of sleep disturbances, making it harder to diagnose sleep apnea.
● Pregnancy: Pregnancy is a period associated with significant hormonal changes, and sleep-related disorders are quite prevalent, particularly in the last trimester. Symptoms associated with sleep apnea, including snoring, frequent awakenings at night, and inability to breathe when lying down, occur in women during pregnancy. Weight gain and fluid retention associated with pregnancy are major contributors to the development of sleep apnea, making people prone to it.
● Menopause: The latter is perhaps the most important sleep apnea period in women. Hormonal change during this stage of menopause is characterized by a decrease in estrogen and progesterone, which alters a woman's ability to breathe. Estrogen and progesterone have been known to stabilize muscular tone of the airways, and hence, their decline in menopause contributes much to the airway collapsing. Some women begin to experience worsening of sleep apnea or may even start experiencing sleep apnea for the first time during menopause.
Weight Distribution Differences
Weight has been shown to be a risk factor for obstructive sleep apnea in men and women, and it appears to have a sex-specific distribution of body fat. In men, fat tends to localize within the abdomen and around the neck area, which increases the tendency for obstruction of airways in sleep. In females, it tends to increase primarily at the hips and thighs, with much less impact on the airway.
Although women typically increase their body weight in the upper part of the body much like in men, at the postmenopausal stage, they are at an increased risk of gaining upper body weight. This is because most postmenopausal women acquire upper body weight gain due to the deposition of excess fat in the upper part of the body which contributes to sleep apnea risk. Obesity is also a major risk factor for sleep apnea in both men and women, though neck and upper body obesity is a major risk factor.
Other Female-Specific Risk Factors
Apart from hormonal influence and body weight, there are several female-specific risk factors for developing sleep apnea.
● Polycystic Ovary Syndrome (PCOS): Women suffering from PCOS are more prone to sleep apnea. PCOS is a hormonal endocrine disorder affecting females in the reproductive age group. There are symptoms like irregular menses, hyperandrogenism, and polycystic ovaries. Women with PCOS have a tendency to be overweight or obese, which is predisposed to sleep apnea. In addition, hormonal imbalances of the condition also influence breathing and sleeping patterns, further boosting its development.
● Gestational Diabetes: Pregnant women suffering from gestational diabetes are liable to suffer from sleep apnea. Gestational diabetes is associated with obesity and insulin resistance. Both of these factors are risk factors for sleep apnea. Pregnant women with sleep apnea are at risk of developing high blood pressure, preeclampsia, and preterm birth. Thus, it has become important to diagnose and treat the disease while pregnant.
● Postpartum Sleep Deprivation: Many women experience sleep deprivation within two weeks after having a child, mainly because of the significant care required by the newborn. Chronic sleep deprivation worsens symptoms of sleep apnea and makes it more challenging for women to suspect or seek treatment for their condition.
Sleep apnea is not the "men's disease". Women also suffer from it but in different ways. This is a vital issue because sleep apnea remains underdiagnosed in women, and many of them are not given proper treatment. Hence, knowing the distinctive symptoms, risk factors, and physiological hormonal effects that contribute to sleep apnea in women has a crucial role in enhancing the diagnosis and treatment processes. Recognizing these differences will help healthcare providers deliver care that ensures effective management of this serious sleep disorder in women.
FAQ
Q1. What is sleep apnea, and how does it affect women?
Ans. Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. In women, sleep apnea often goes underdiagnosed because symptoms can present differently compared to men. While men typically experience loud snoring and observable pauses in breathing, women may experience more subtle signs such as fatigue, insomnia, headaches, and mood disturbances. Hormonal differences, particularly during menopause, can also play a role in how sleep apnea manifests in women.
Q2. Are the symptoms of sleep apnea different in women compared to men?
Ans. Yes, women may experience different symptoms of sleep apnea. While both men and women can suffer from excessive daytime sleepiness, women are more likely to report insomnia, anxiety, depression, and fatigue rather than the classic symptoms like loud snoring or observed breathing pauses. Women may also experience headaches in the morning, difficulty focusing, and mood swings. These more subtle symptoms can make diagnosis more challenging in women.
Q3. How does sleep apnea in women change with age?
Ans. In women, sleep apnea risk tends to increase with age, particularly around and after menopause. Hormonal changes during this time can lead to weight gain, reduced muscle tone in the airway, and shifts in breathing patterns, all of which can contribute to the development or worsening of sleep apnea. Younger women may have a lower risk compared to men, but post-menopausal women have a significantly higher risk, making age a key factor in the development of sleep apnea in women.
Q4. Is sleep apnea less common in women than in men?
Ans. While sleep apnea has traditionally been diagnosed more frequently in men, research suggests it may be underdiagnosed in women due to differences in symptoms. Historically, the condition was thought to be much more common in men, but as awareness has grown, studies have shown that the gap may not be as wide as previously believed. The subtle nature of symptoms in women often leads to misdiagnosis or delayed diagnosis.
Q5. How do hormonal changes impact sleep apnea in women?
Ans. Hormonal fluctuations, particularly the decline in estrogen and progesterone during menopause, play a significant role in the development of sleep apnea in women. Estrogen and progesterone are believed to protect against sleep apnea by maintaining muscle tone in the airway and regulating breathing patterns. As these hormone levels drop, the risk of airway collapse during sleep increases, making post-menopausal women more susceptible to sleep apnea.
Q6. Can pregnancy trigger sleep apnea in women?
Ans. Yes, pregnancy can trigger or worsen sleep apnea, especially in the third trimester. Weight gain and hormonal changes during pregnancy can lead to increased airway resistance, making it harder for pregnant women to breathe comfortably while sleeping. This form of sleep apnea is often referred to as gestational sleep apnea. If untreated, it can pose risks to both the mother and the baby, including high blood pressure, preeclampsia, and gestational diabetes.
Q7. What treatments are available for women with sleep apnea?
Ans. The treatments for sleep apnea in women are similar to those for men and may include lifestyle changes, Continuous Positive Airway Pressure (CPAP) therapy, oral appliances, and, in severe cases, surgery. However, since women often present with different symptoms, treatment approaches might focus more on improving sleep quality and addressing related issues like insomnia, fatigue, and mental health symptoms. Weight management, avoiding alcohol and sedatives before bedtime, and practicing good sleep hygiene can also be part of an effective treatment plan.
Q8. Why is sleep apnea often misdiagnosed in women?
Ans. Sleep apnea is often misdiagnosed in women because the symptoms may not fit the traditional profile seen in men. Women are more likely to be diagnosed with conditions like depression, insomnia, or chronic fatigue due to the overlap in symptoms. The lack of loud snoring or noticeable breathing pauses, which are hallmark signs in men, further complicates the diagnosis for women. Physicians and patients alike may not always associate the more subtle symptoms women experience with sleep apnea, leading to underdiagnosis.
Q9. Are there any long-term health risks of untreated sleep apnea in women?
Ans. Yes, untreated sleep apnea in women can lead to several long-term health risks, similar to those seen in men. These include an increased risk of heart disease, high blood pressure, stroke, diabetes, and depression. Additionally, sleep apnea can severely impact cognitive function, emotional well-being, and overall quality of life. Women with untreated sleep apnea may also face a higher risk of complications during pregnancy, as well as a greater chance of developing mental health issues due to chronic sleep deprivation.
Q10. What steps can women take if they suspect they have sleep apnea?Ans. If a woman suspects she may have sleep apnea, the first step is to consult a healthcare provider or sleep specialist. Keeping track of sleep patterns, symptoms such as frequent nighttime awakenings, morning headaches, or excessive daytime sleepiness, can provide valuable information during the diagnosis process. A sleep study (polysomnography) may be recommended to accurately diagnose the condition. Additionally, addressing lifestyle factors such as weight, stress levels, and sleep hygiene can help in managing symptoms while seeking a formal diagnosis and treatment plan.
