Large breast size tied to migraine, neck pain, sleep apnea

Clinical takeaway: Consider screening women with symptomatic macromastia who present with headache or neck symptoms for chronic migraine, cervical radiculopathy, and obstructive sleep apnea, as these conditions may occur more frequently in this population.

Headache is often cited as a symptom of macromastia and can support insurance approval for breast reduction surgery, yet little research has examined whether enlarged breast tissue is associated with specific headache disorders. Better understanding of these relationships could help clinicians provide more comprehensive evaluation and management of women with chronic head and neck pain.

In this cross-sectional analysis, investigators reviewed electronic health records for 687 women treated in Stanford-affiliated neurology and headache clinics between 2017 and 2024, including 347 women with macromastia and 340 matched controls without the condition. After accounting for differences in age, BMI, depression, anxiety, and other factors, women with macromastia were 40% more likely to have chronic migraine, 54% more likely to have obstructive sleep apnea, about twice as likely to have neck pain, and more than twice as likely to have cervical radiculopathy.

The absolute burden of symptoms was notable. Nearly half of women with macromastia had chronic migraine (48% vs 32% of controls), 57% had neck pain (24% of controls), 43% had obstructive sleep apnea (22% of controls), and 15% had cervical radiculopathy (5% of controls). A higher prevalence of occipital neuralgia was observed numerically, but the association did not remain statistically significant after adjustment.

Among women with macromastia, neck pain was the only condition associated with a greater likelihood of undergoing breast reduction surgery. The authors noted that the findings do not establish causality but suggest that symptomatic macromastia may be associated with a broader pattern of neurological and sleep-related disorders that warrants further study.

“Many people think of enlarged breast tissue primarily as a cosmetic issue, but our findings suggest it may be associated with a broader range of women’s health concerns, including chronic migraine, neck pain and sleep-related breathing disorders,” said lead author Kristyn Pocock, MD.
