A new study published in the Headache Journal suggests a link between macromastia, a condition characterized by abnormally large breasts relative to a person's frame, and an increased risk of certain health issues beyond physical discomfort.
The research, which analyzed health records of 687 women treated at headache and neurology clinics, found that women with enlarged breast tissue were twice as likely to experience neck pain and more than twice as likely to have cervical radiculopathy, also known as a pinched nerve in the neck. Furthermore, almost 50% of women with macromastia reported a higher likelihood of obstructive sleep apnea, a condition where throat muscles relax and block the airway during sleep.
Perhaps more surprisingly, the study indicated that women with macromastia were approximately 40% more likely to suffer from chronic migraines compared to women without the condition. While insurance companies acknowledge a connection between enlarged breasts and headaches, the broader links to neurological conditions have been less understood.
Lead study author Kristyn Pocock stated that these findings suggest that enlarged breast tissue may be associated with a wider range of women's health concerns, moving beyond the perception of it being solely a cosmetic issue. "By better understanding these connections, we can help ensure women receive more comprehensive evaluations and care for symptoms that may affect their daily lives," Pocock said in a press release.
The study also noted that neck pain was the primary condition influencing women's decisions to seek breast reduction surgery. While macromastia is relatively common, a rarer condition called gigantomastia can result in excessively large breasts, with only about 300 documented cases globally. Gigantomastia can be influenced by puberty, pregnancy, medications, obesity, autoimmune disorders, or hormonal imbalances, and symptoms can include pain, poor posture, nipple numbness, infections, and psychological distress such as anxiety and depression.
While the current findings offer new insights into the condition and its impact on women's health, further research is deemed necessary to fully understand the mechanisms linking macromastia to neck pain, migraines, and sleep apnea, and to explore potential treatment benefits.
