New research suggests women with macromastia may face higher risks of chronic migraine, neck pain, and obstructive sleep apnea.
Key facts
- •Macromastia is estimated to affect approximately 1–5% of women, with prevalence increasing after menopause.
- •The study cohort consisted of 687 females treated at headache and neurology clinics.
- •A 2025 pilot study of 34 women found that 79% reported at least a 50% reduction in monthly headache days after breast reduction surgery.
- •Non-surgical management strategies include physical therapy, weight management, and the use of properly fitted, supportive bras.
- •Researchers state that further investigation is needed to determine if treating macromastia can effectively alleviate chronic migraine and sleep apnea.
A study published September 22 in Headache: The Journal of Head and Face Pain found that women with macromastia, or enlarged breasts, have higher odds of experiencing chronic migraine, neck pain, and obstructive sleep apnea. Researchers analyzed medical records from 687 patients treated at Stanford Medical Center clinics between 2017 and 2024 to identify these potential health associations.
By the numbers
Study Scope and Limitations
The research was a retrospective, cross-sectional analysis comparing 347 women with macromastia to 340 without the condition. Because the study relied on existing medical records rather than tracking participants over time, it does not prove that macromastia causes these health conditions. Researchers noted that while larger breasts may place physical strain on the neck and back, the exact biological mechanisms behind these associations remain unclear.
Treatment and Surgical Considerations
While breast reduction surgery is a common treatment for physical discomfort, the study found that only neck pain was significantly associated with patients having undergone the procedure. Migraine and sleep apnea were not significantly linked to surgical intervention in the records reviewed. However, small pilot studies from 2025 and 2026 co-authored by lead researcher Dr. Kristyn Pocock indicated potential improvements in headache frequency and sleep apnea risk following surgery, though experts emphasize that larger studies are required before surgery can be considered a standard treatment for these conditions.
