How Does Menopause Affect Bone Density?
The hallmark of menopause is the loss of ovarian estrogen production. Estrogen helps prevent bone resorption, or breakdown, but does not build bone. Women can lose up to 10% of bone mass within five years of menopause. Brittle bones can have a big impact on health and quality of life as a woman ages and can lead to frailty fractures.
A bone density (DXA) scan is a quick, easy way to assess skeletal health and fracture risk. We recommend that women get a baseline DXA scan around the time of menopause and monitor every few years depending on results and risk factors.
Adequate calcium intake (1,200 mg per day from all sources, including diet and supplements) plus 2,000 international units (IU) of vitamin D3 daily helps to build bone. So does weight-bearing exercise, such as walking, jogging, yoga, Pilates, weight lifting, and resistance bands. Getting adequate protein in a diet to maintain muscle mass, which diminishes during menopause, is also important.
