It’s long been known that menopause and its drop in estrogen can lead to thinning bones and osteoporosis. Evidence now suggests that women who get hot flashes may be more likely to get bone fractures later. A 2015 study looked at data from the Women’s Health Initiative Clinical Trial, an eight-year study of nearly 30,000 women ages 50-79 who did not use hormone replacement therapy.The researchers found that women who’d had moderate or severe hot flashes were nearly twice as likely to get hip fractures during the study period as those who did not have hot flashes. The women with hot flashes also had lower bone mineral density.
