Bone loss occurs when?

Bone loss occurs when?

• A. when bone resorption exceeds bone formation
• B. when bone resorption exceeds bone formation, occurs with menopause and advancing age
• C. during rapid bone formation in youth
• D. when calcium intake is high and physical activity increases

Answer: (B)

Bone loss happens when bone resorption outpaces bone formation, so net bone mass declines. This imbalance is especially evident with menopause and aging, when reduced estrogen accelerates bone resorption and formation can’t keep up, leading to weaker bones. In contrast, rapid bone formation in youth builds bone mass, and higher calcium intake with more physical activity generally protects against loss.
