Bone Loss and Osteoporosis
Captions available
The idea
Bone density peaks in early adulthood and then declines; osteoporosis is a disease of low bone mass with fracture risk, far commoner in women after menopause.
In practice
Calcium with vitamin D, and weight-bearing and strength-training exercise, protecting bone.
Where people slip
The misconception is that osteoporosis is normal aging; gradual bone loss is normal, but osteoporosis is a disease.
