Study Links Enlarged Breast Tissue to Chronic Migraine, Neck Pain, and Sleep Apnea in Women

The study analyzed electronic health records of 687 women treated at headache and neurology clinics affiliated with Stanford Medical Center between 2017 and 2024. This group included 347 women diagnosed with macromastia and 340 without the condition. After controlling for age, body mass index, anxiety, and depression, researchers found that women with macromastia were sixty percent more likely to suffer from chronic migraine, were twice as likely to experience neck pain, about fifty percent more likely to have obstructive sleep apnea, and more than twice as likely to have cervical radiculopathy compared to those without the condition.

Kristyn Pocock, M.D., a lead researcher and assistant professor of neurology at Wake Forest, stated that many perceive enlarged breast tissue as merely a cosmetic issue, but the findings indicate it could be related to a broader range of women's health concerns, including chronic migraine and sleep-related disorders. She emphasized the need for comprehensive evaluations and care for symptoms affecting women's daily lives.

Women with macromastia often report headaches, neck and back pain, and shoulder discomfort, with some seeking breast reduction surgery for relief. Although headaches are acknowledged by insurers as a symptom of macromastia, there is limited understanding of how enlarged breast tissue relates to specific headache disorders and other neurological conditions.

The study also evaluated factors that lead women with macromastia to undergo breast reduction surgery, finding significant links to neck pain. While the research uncovers important associations, further studies are required to explore how macromastia contributes to these symptoms and whether treatment could alleviate them.

Pocock highlighted that these findings raise critical questions about the painful effects of enlarged breast tissue on women and the potential benefits of treating macromastia.
