Chronic migraines may have an overlooked connection to breast size

Key Points:

• A new study led by Kristyn Pocock at Wake Forest University reveals that women with enlarged breast tissue experience higher rates of chronic migraine, neck pain, pinched neck nerves, and sleep apnea compared to women without enlarged breasts.
• The study analyzed medical records from Stanford Medicine, matching 347 women diagnosed with enlarged breast tissue to a control group of similar age, race, and body mass index, finding that neck pain and chronic migraine were significantly more common in the macromastia group even after adjusting for confounding factors.
• Among women with enlarged breasts, only neck pain was linked to a higher likelihood of undergoing breast reduction surgery, while chronic migraine and other conditions did not influence surgical decisions.
• Researchers suggest that the physical load of large breasts, restricted chest expansion affecting breathing during sleep, and hormonal or inflammatory effects of breast tissue may contribute to these health issues, though causality cannot be established from this retrospective study.
• The study highlights the need for prospective research to determine whether breast reduction surgery can effectively relieve headaches and other symptoms, as current evidence is limited and mixed regarding postoperative improvements.
