Decreasing bone mass in women begins at which age?

• A. 40 years old
• B. 45 years old
• C. 50 years old
• D. 60 years old

Answer: (C)

Estrogen loss after menopause causes bone density to decline more rapidly. Bone mass peaks in our late teens to early 20s, then gradually decreases with age, but the decline accelerates when menopause hits because estrogen levels fall. This menopausal drop typically occurs around age 50, making bone loss begin more noticeably at that time. So, around fifty years old is when the decrease in bone mass commonly starts in women.
