How is osteoporosis related to menopause?
At menopause, there’s a dramatic decline in the female hormone, estrogen. This decline in estrogen slows the bone remodeling process and causes an accelerated rate of bone loss. This more rapid loss of bone continues for about 10 years after menopause. The rate of bone loss eventually returns to premenopausal levels. But bone formation does not. This causes postmenopausal women to have a much greater chance of having a fracture. In addition, having an early menopause (before age 40) also increases the chance of osteoporosis and fractures. Having prolonged periods of time when hormone levels are low and/or absent, such as can happen with excess exercise, causes loss of bone mass and osteoporosis.
