- A new study found that women with macromastia (enlarged breasts) had higher odds of chronic migraine, neck pain, and obstructive sleep apnea than women without the condition.
- The findings suggest that macromastia may lead to more than physical discomfort, potentially contributing to multiple health conditions that affect quality of life.
- Women with macromastia experiencing frequent headaches, neck pain, or poor sleep quality should talk with their doctor to learn about their treatment options.
- General macromastia is often treated with breast reduction surgery, but other strategies, such as a supportive bra and physical therapy, may help alleviate discomfort.
Enlarged breast tissue, known medically as macromastia or breast hypertrophy, is relatively common among women.
The exact prevalence of the condition is not fully understood, but some research estimates that macromastia affects around 1–5% of women.
This estimate climbs after menopause, with around 18.6% of women experiencing an increase in breast size, which may be linked to weight gain and hormonal shifts.
However, macromastia can occur during other life stages, such as puberty or pregnancy.
Women with disproportionately large breasts often experience discomfort and pain, and may turn to breast reduction surgery for relief.
Now, new research suggests that macromastia is associated with more than just physical pain.
“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,” lead study author Kristyn Pocock, MD, assistant professor of neurology at Wake Forest University School of Medicine, said in a news release.
“By better understanding these connections, we can help ensure women receive more comprehensive evaluations and care for symptoms that may affect their daily lives.”
To better understand how macromastia may impact quality of life, researchers reviewed medical records from 687 females treated at headache and neurology clinics affiliated with Stanford Medical Center from 2017 to 2024.
The cohort included 347 females with macromastia and 340 without.
After accounting for factors including age, body mass index (BMI), depression, and anxiety, researchers found that those with macromastia were:
- 40% more likely to have chronic migraine (a headache on at least 15 days per month for more than 3 months)
- roughly twice as likely to experience neck pain
- 54% more likely to have obstructive sleep apnea (OSA)
- more than twice as likely to have cervical radiculopathy, a condition caused by irritation or compression of nerves in the neck
The study was a retrospective, cross-sectional analysis, meaning researchers reviewed existing medical records rather than following participants over time.
This means the study does not prove that macromastia causes migraine, neck pain, or sleep apnea, warranting further investigation.
“These findings raise important questions about how enlarged breast tissue may contribute to painful symptoms for women,” Pocock said. “More research is needed to determine whether treating macromastia could help certain women find relief and enhance quality of life.”
Researchers don’t yet have an explanation for why macromastia is associated with these health conditions.
Larger breasts can place additional load on the neck, shoulders, and upper back, which may contribute to musculoskeletal pain and nerve irritation.
Pocock has also discussed how other factors may play a role, such as:
- inflammation
- hormonal effects
- mood changes
- physical activity
- sleep quality
Further studies are needed to determine the exact role these cofounding factors may play in the possible health effects of macromastia.
The researchers examined breast reduction surgery among people with macromastia.
Of the symptoms studied, neck pain was significantly associated with undergoing breast reduction surgery, known as a reduction mammoplasty.
Migraine, sleep apnea, and cervical radiculopathy were not significantly associated with this surgical treatment.
This finding raises questions about whether some symptoms associated with macromastia may be overlooked when people seek treatment, suggesting another avenue for further research.
Preliminary evidence indicates that breast reduction surgery may help some people with headaches, but the evidence is still limited.
In a small 2025 prospective pilot study, which was also co-authored by Pocock, 34 women with symptomatic macromastia and headaches underwent breast reduction. At follow-up, 79% reported at least a 50% reduction in monthly headache days. Headache frequency, severity, and related disability also improved.
Another pilot study led by Pocock published in 2026 found improvements in headache frequency, severity, disability, and sleep apnea risk after surgery. The sample size for this study was also small, with 34 participants, highlighting the need for further research.
The researchers also emphasized that breast reduction should not yet be considered a treatment for headaches because larger studies are still needed.
Sherry Ross, MD, co-founder of Oneself, Intimate Skin Care, and the Pair-a-Docs Podcast, said that women with macromastia experiencing chronic pain may wish to consider breast reduction surgery.
“In my 30+ years as a practicing OB-GYN, I have never met anyone who regretted having breast reduction surgery,” she told Healthline.
If you live with macromastia and experience frequent headaches, persistent neck or shoulder pain, numbness or tingling, loud snoring, or significant daytime fatigue, it’s important to discuss all of your symptoms with your doctor.
A comprehensive evaluation can help guide you to the treatment that you need, whether it’s breast reduction surgery or other methods.
Your healthcare team may recommend a more supportive bra, physical therapy, or an NSAID or other pain reliever to help you find relief.
“The most important step in improving your comfort and health is to get a properly fitted bra,” Ross said.
“There are dedicated bra stores that can properly fit larger-breasted women with full-coverage, well-supported bras, with and without underwire… both for everyday wear and for exercise.”
She recommended exercises that are better suited to larger breasts to avoid excessive breast bouncing and discomfort, such as:
- swimming
- cycling
- walking
- strength and resistance training
“Strength training that focuses on the upper body and core is helpful as well,” Ross said. “Select workout clothing that is comfortable, breathable, and moisture-wicking to avoid excessive sweat and moisture buildup.”
