The primary reason for the higher prevalence of osteoporosis (bone loss) in women compared to men stems from hormonal and structural factors. The main hormonal contributor is the sudden drop in estrogen levels during menopause. Given estrogen's critical role in maintaining bone density, this reduction accelerates bone loss. From a structural perspective, women's bone density is generally lower than men's, and their bone structures are thinner. Furthermore, muscle mass in women is less than in men, which is a factor influencing bone health and strength. This combination makes women more vulnerable to osteoporosis.
