Women often experience vague symptoms such as headaches, anxiety, or excessive daytime sleepiness, which may be linked to a health condition known as obstructive sleep apnea (OSA). Historically, OSA was classified as a male disease, with its typical presentation largely based on studies involving men. Research since the 1990s has shown that OSA presents differently in women, who may not exhibit common signs like snoring.

The condition leads to repeated breathing interruptions during sleep, primarily affecting air passage. While classic symptoms include loud snoring and gasps for air—which are often associated with men—women are more prone to experience nightmares, frequent awakenings, insomnia, and daytime fatigue. Studies indicate that females often show more hypopneas, or shallow breaths, while males are more likely to have apneas, or complete pauses in breath.
Factors such as hormonal fluctuations, anatomical differences in the upper airway, and social stigma around female sleep behaviors contribute to these disparities. Jennifer Martin, PhD, a specialist in behavioral sleep medicine, states that traditional definitions of sleep apnea do not adequately encompass how men and women’s breathing patterns differ.
Prior to menopause, sleep apnea tends to be less common and milder in women, making up about 41% of cases, compared to 59% in men. However, after menopause, the prevalence and severity of OSA in women can rise significantly; studies show that 47% to 67% of postmenopausal women may experience the condition, rivaling men in the same age group.
Despite having less severe forms of the disorder overall, women often face more pronounced symptoms. Misdiagnosis is frequent due to the absence of typical symptoms. Women might bring complaints of fatigue and sleep disturbances to their doctors, only to be misattributed to anxiety, depression, or menopause. Research highlights that men are nine times more likely to receive referrals for diagnostic testing compared to women.
Common home sleep apnea tests may miss the condition in women since they often manifest milder symptoms. Moreover, testing inaccuracies are exacerbated for women experiencing insomnia, who may not get adequate sleep during assessments. This leads to an underdiagnosis of sleep apnea, with many women likely unaware of their condition.
If untreated, OSA can lead to serious health issues including cardiovascular problems, as the constant breathing interruptions can strain the heart. Studies suggest that women with severe sleep apnea may experience higher rates of cardiovascular complications than their male counterparts. Additionally, untreated OSA could lead to cognitive difficulties and negatively affect overall wellbeing, including relationships and mental health.
Women are encouraged to monitor their daytime energy levels, take note of snoring, and manage other health conditions to mitigate OSA symptoms. Advocating for themselves in medical settings is essential, especially as diagnosis criteria are predominantly male-focused. With appropriate treatment, research indicates women can benefit significantly from addressing sleep apnea.
