Sticks and stones

Remember that nursery rhyme from days gone by? It appears that vasomotor symptoms, including hot flashes and night sweats, may be as powerful in contributing to breakage as sticks and stones. Or at least in contributing to a lower bone mineral density (BMD). BMD reflects the strength of an individual’s bone, usually in relation to calcium content.

Researchers analyzed data for 2,213 women participating in the Study of Women’s Health Across the Nation. At the time of the study, all participants had their uteri intact, were not using hormones and were determined to be in pre- or perimenopause.  Menopausal stage and vasomotor symptoms were assessed via questionnaire and BMD was analyzed at yearly follow up visits.

The results, which are published in the March/April edition of Menopause, showed that BMD was consistently lower among women who had had vasomotor symptoms than among women who had not. These findings remained even after researchers adjusted for factors such as age, time within each menopausal stage, race/ethnicity, study site, and stage of menopause at the time that the study began.

Additionally, BMD was even lower among women who had more frequent night sweats and/or hot flashes than those who did not.

Notably, these effects varied by anatomic site and were most prevalent in the lumbar spine and hip in postmenopausal women, and at the femoral neck (pelvic region) among pre and perimenopausal women. More troubling, even women in the earliest stages of menopause also experiencing vasomotor symptoms  had lower bone mineral density than those who did not.

According to the National Osteoporosis Foundation, it is never too late to start a program aimed at halting bone loss and preventing future fractures. Because data are now suggesting that vasomotor symptoms may be linked to lower bone mineral density, it might be worthwhile to speak to your doctor to determine if you should undergo BMD testing. Other important steps include making sure that you are getting adequate amounts of vitamin D and calcium, engaging in weight-bearing activity, avoiding cigarettes and minimizing alcohol intake.

There is not time like the present to avoid potential pitfalls (no pun intended). Only you and your health practitioner can determine the proper steps to take. I’d also encourage you to read more about osteoporosis at the National Osteoporosis Website. The information is thorough and easy to navigate through.

Sticks and stones may break your bones. And hot flashes and night sweats might hurt you? Yikes!
