How does menopause affect bone density?

Menopause significantly impacts bone physiology, primarily through the decline of estrogen production. While human bone density typically reaches its peak around age 30 and undergoes a gradual, age-related decline, this process accelerates markedly at the onset of and for several years following menopause.123

This accelerated loss occurs because estrogen plays a critical role in suppressing bone resorption—the process by which bone is broken down. The resulting reduction in bone mass can lead to osteopenia, a minor reduction in bone mass, or osteoporosis, a severe condition characterized by porous, fragile bones that are highly susceptible to fractures from minor stresses.142

To mitigate these effects, medical professionals may consider hormone replacement therapy, as estrogen administration has been shown to increase bone density and decrease fracture risk. Additionally, bone loss can be managed through lifestyle interventions, including regular weight-bearing exercise, proper nutrition, and adequate intake of calcium and vitamin D.12
