Dear Dr. Donohue: When my nearly 30-year-old daughter had an X-ray a few years ago, the doctor told her she had the bones of an older woman. A few weeks ago, after an accident, she had X-rays and was told the same thing. She was advised to take calcium and exercise. (She does water aerobics.) What would cause the aging of her bones? No doctor has ever told her why this has happened. — J.L.

A: When the doctors say her bones look old, they’re saying that her bones are showing some osteoporosis, something that should not happen to a woman’s bones until menopause. Your daughter cannot ignore this. She should report it to her family doctor.
