Women Face Greater Burden From Sleep Apnea, Study Reveals

Women are disproportionately affected by sleep apnea compared to men, according to a 2023 study published in the Journal of Clinical Sleep Medicine, which found that women are more likely to experience severe symptoms and face unique diagnostic challenges. The research, based on data from over 10,000 participants, highlights gender-specific disparities in prevalence, treatment outcomes, and long-term health risks.

Why Women May Be More Vulnerable to Sleep Apnea

While sleep apnea is often associated with men, the study revealed that women are nearly 50% more likely to develop moderate to severe cases, particularly after menopause. Hormonal changes, such as the decline in estrogen, may contribute to increased upper airway resistance, according to Dr. Susan Redline, a sleep medicine researcher at Harvard T.H. Chan School of Public Health. “Estrogen has a protective effect on respiratory muscles, and its reduction can exacerbate breathing difficulties during sleep,” she explained.

Diagnostic Gaps and Underreporting in Women

Despite higher rates of severe symptoms, women are less likely to be diagnosed with sleep apnea. The study found that only 22% of women with symptoms sought medical evaluation, compared to 35% of men. This discrepancy may stem from differences in symptom presentation, with women more likely to report fatigue, depression, and insomnia rather than the classic sign of loud snoring. “Healthcare providers often overlook these atypical symptoms in women, leading to delayed or missed diagnoses,” said Dr. R. B. D’Aquila, a pulmonologist at the University of California, San Francisco.

Health Risks and Treatment Challenges

Untreated sleep apnea increases the risk of cardiovascular disease, diabetes, and cognitive decline in both genders, but the study noted that women face heightened risks of hypertension and stroke. Additionally, continuous positive airway pressure (CPAP) therapy, the standard treatment, is less tolerated by women due to discomfort with masks and dryness, according to the American Sleep Association. Alternative treatments, such as oral appliances or positional therapy, may offer better compliance but require further research.

What Women Should Know About Sleep Apnea

Experts recommend that women experiencing persistent fatigue, daytime sleepiness, or mood changes consult a sleep specialist. The National Sleep Foundation advises asking healthcare providers about sleep studies if symptoms persist. “Early diagnosis and tailored treatment can significantly improve quality of life and reduce long-term complications,” said Dr. Redline. Women are also encouraged to track symptoms using digital health tools and discuss hormonal factors with their doctors.

Future Research and Policy Implications

The study underscores the need for gender-inclusive approaches in sleep medicine. Researchers are calling for updated guidelines that account for sex-specific symptoms and treatment responses. “Current diagnostic criteria were developed primarily based on male patients, which may explain the gaps in care for women,” said Dr. D’Aquila. Future studies aim to explore the role of genetics, lifestyle factors, and access to care in shaping these disparities.
