What accelerates bone loss after menopause?

• A. Decreased estrogen levels
• B. Increased calcium intake
• C. Regular exercise
• D. Sunlight exposure

Answer: (A)

After menopause, estrogen levels fall, and estrogen normally helps keep bone from being broken down too quickly. It limits osteoclast formation and activity and helps balance signaling in bone remodeling. When estrogen drops, osteoclasts become more active, increasing bone resorption relative to formation, so bone density declines faster. That rise in bone breakdown is what accelerates bone loss after menopause. Calcium intake, regular exercise, and sun-derived vitamin D support bone health, but they don’t drive the rapid loss seen with estrogen deficiency; in fact, they help slow it down.
