Which change in bone mass is commonly associated with aging?

• A. Increase in bone mass
• B. Loss of bone mass
• C. No change in bone mass
• D. Dense bone formation

Answer: (B)

As people age, the balance of bone remodeling shifts toward loss rather than gain. Bone resorption by osteoclasts tends to outpace formation by osteoblasts, so net bone mass decreases over time. Hormonal changes, especially reduced estrogen after menopause, accelerate this process. Lower calcium and vitamin D absorption, reduced physical activity, and other aging-related factors further contribute to weaker, less dense bones. That combination makes loss of bone mass the common aging change. The notions of increasing bone mass, no change, or dense bone formation do not align with the typical aging pattern.
