Effect of early menopause on bone mineral density and fractures

Abstract

In Brief Objective: To review the data on the effect of early menopause on bone. Do women undergoing early menopause develop lower bone mineral density at an earlier age and do they have a higher incidence of osteoporotic fractures? Is there a difference on bone between women who undergo early natural menopause compared to women who have early menopause after oophorectomy? Results: The earlier in life that menopause occurs, the lower the bone density will be later in life. Low bone density is associated with a higher fracture rate, and several studies show a relationship between early menopause, oophorectomy, and an increase in osteoporotic fractures. Conclusions: Early menopause is a risk factor for osteoporosis. Women with an early menopause should have bone density testing performed within 10 years of menopause so that osteopenia or osteoporosis will be diagnosed early and appropriate antiresorptive therapy initiated. Early menopause is associated with earlier bone loss, resulting in an increased incidence of osteoporotic fractures. There are no data to show that bone loss or fractures occur more commonly after oophorectomy than after early nonsurgical menopause.
