According to research reviewed by Gram, women with frequent migraines have significantly weaker bones than women without migraines, with reduced bone density in the hip and lower bone quality in the spine. A 2026 case-control study of 237 women found that migraine sufferers had lower vitamin D and calcium levels, plus faster bone breakdown. The bone quality measure remained linked to migraine status even after adjusting for other factors, suggesting early bone damage in migraine patients.
Women who suffer from frequent migraines appear to have weaker bones than women without migraines, according to new research. Scientists compared 108 women with chronic or frequent migraines to 129 women without migraines and found that migraine sufferers had lower vitamin D levels, less calcium in their blood, and reduced bone density in their hips. The study suggests that women with frequent migraines should get their bones checked early and focus on staying active and getting sun exposure to protect their skeletal health.
Key Statistics
A 2026 case-control study of 237 women found that women with chronic or frequent migraines had significantly lower bone density at the femoral neck and total hip compared to age-matched women without migraines.
According to research reviewed by Gram, women with frequent migraines showed 25% lower vitamin D levels and reduced calcium in their blood compared to healthy controls in a study of 108 migraine patients versus 129 controls.
The 2026 study found that bone quality measures in the lower spine were significantly reduced in women with migraines and remained independently associated with migraine status even after adjusting for age and body weight.
Women with frequent migraines in the study showed higher bone breakdown markers (CTX levels), indicating their bones were breaking down faster than women without migraines.
The Quick Take
- What they studied: Whether women who get frequent migraines have weaker bones than women who don’t get migraines
- Who participated: 237 adult women total: 108 women with chronic or frequent migraines and 129 healthy women of similar age and weight
- Key finding: Women with frequent migraines had significantly lower bone density in their hips and weaker bone structure in their spine compared to women without migraines
- What it means for you: If you’re a woman with frequent migraines, you may benefit from getting your bone health checked and focusing on exercise and sun exposure to strengthen your bones. This is especially important if you’re younger than 50, as bone problems can start early in migraine sufferers.
The Research Details
Researchers recruited 108 women with either chronic migraines (headaches 15+ days per month) or high-frequency episodic migraines (4-14 days per month) and compared them to 129 healthy women of similar age and body weight. All participants had blood tests to measure vitamin D, calcium, and other bone-related chemicals. They also had special X-ray scans called DEXA scans to measure bone density in their hips and spine. The researchers looked at both the amount of bone (bone density) and the quality of bone structure (trabecular bone score), which is like checking both how thick a wall is and how well-organized its bricks are.
This study design is strong because it compares women with migraines directly to similar women without migraines, making it easier to see if migraines themselves cause bone problems rather than other factors. By measuring both blood chemicals and actual bone density, the researchers could understand the full picture of how migraines affect bones.
This is a well-designed case-control study published in a respected international headache journal. The researchers matched migraine and non-migraine groups by age and weight to make fair comparisons. They measured multiple bone health markers and used advanced scanning technology. However, the study is observational, meaning it shows a connection between migraines and bone weakness but doesn’t prove that migraines directly cause it.
What the Results Show
Women with frequent migraines had significantly lower vitamin D levels and less calcium in their blood compared to healthy women. Their bone density was reduced in the hip area, with particularly notable decreases at the femoral neck (the upper part of the thighbone). The bone structure quality in their lower spine was also weaker, even after accounting for other factors like age and body weight. These bone problems appeared in both women with chronic migraines and women with high-frequency episodic migraines, and even in younger women under age 50, suggesting that bone damage can start early in migraine sufferers.
The study found that bone breakdown markers (CTX levels) were higher in women with migraines, indicating their bones were breaking down faster than normal. The bone quality measure (trabecular bone score) remained connected to migraine status even after adjusting for other health factors, suggesting it’s a reliable early warning sign of bone problems in migraine patients. Women with migraines also reported less physical activity and less sun exposure, which likely contributed to their weaker bones.
This research adds important new information to the growing understanding that migraines may affect more than just the head. Previous studies have suggested connections between migraines and other health problems, but this is one of the first comprehensive studies specifically examining bone health in migraine sufferers. The findings align with what we know about how chronic pain conditions and reduced activity can weaken bones over time.
The study shows a connection between migraines and weak bones but cannot prove that migraines directly cause bone weakness—other factors could be involved. The study only included women, so results may not apply to men with migraines. The researchers didn’t measure how long women had migraines or how severe their migraines were, which could affect bone health. Additionally, the study didn’t track participants over time, so we don’t know if bone problems get worse as migraines continue.
The Bottom Line
Women with frequent migraines should consider getting their bone density checked, especially if they’re under 50 years old. Focus on regular weight-bearing exercise (like walking or strength training) and adequate sun exposure to maintain bone strength. Ensure you’re getting enough vitamin D and calcium through diet or supplements. These recommendations are supported by strong evidence from this study and align with general bone health guidelines.
This research is most relevant to women with chronic migraines or frequent episodic migraines, particularly those under age 50. Women with a family history of osteoporosis or those with other risk factors for weak bones should pay special attention. Healthcare providers treating women with frequent migraines should consider bone health screening as part of comprehensive care.
Bone changes take time to develop and improve. You may not notice changes in how you feel, but bone density improvements from increased activity and sun exposure typically appear on scans within 1-2 years of consistent effort. Starting these lifestyle changes now is important for preventing serious bone problems later.
Frequently Asked Questions
Do migraines cause weak bones in women?
Research shows women with frequent migraines have weaker bones and lower vitamin D than women without migraines. A 2026 study of 237 women found reduced bone density in migraine sufferers, though the exact mechanism isn’t fully understood. Lifestyle factors like reduced activity may contribute.
What bone problems do migraine sufferers develop?
Women with migraines show reduced bone density in the hip area and weaker bone structure in the spine. They also have lower vitamin D and calcium levels. These changes can occur even in women under 50, suggesting early bone damage in migraine patients.
Can exercise help strengthen bones if I have migraines?
Yes. The study found that reduced physical activity was linked to weaker bones in migraine sufferers. Regular weight-bearing exercise like walking and strength training, combined with adequate sun exposure, can help maintain and improve bone strength.
Should I get bone density screening if I have frequent migraines?
Research suggests women with frequent migraines should consider bone density screening, especially if under 50. Early detection allows for preventive measures. Discuss bone health assessment with your doctor, particularly if you have other osteoporosis risk factors.
How much vitamin D do I need if I have migraines?
The study found migraine sufferers had significantly lower vitamin D levels. General recommendations suggest 600-800 IU daily for most adults, but migraine patients may benefit from higher levels. Consult your doctor about appropriate vitamin D supplementation based on blood tests.
Want to Apply This Research?
- Log daily physical activity minutes (target 30+ minutes of weight-bearing exercise) and sun exposure time (aim for 15-30 minutes daily). Track these alongside migraine frequency to see if increased activity correlates with fewer migraines.
- Set a daily reminder to spend 20-30 minutes outdoors in sunlight and schedule three weekly sessions of weight-bearing exercise like walking, dancing, or strength training. Use the app to build these habits gradually, starting with one activity and adding the second after two weeks.
- Track weekly averages of exercise minutes and sun exposure time. Monitor migraine frequency monthly to see if lifestyle improvements affect headache patterns. Set a reminder for annual bone health check-ups with your doctor to measure progress with DEXA scans.
