Part 1: Understanding Osteoporosis

That response is incorrect. The correct answer was "none of the above."

Osteoporosis is considered to be a "silent disease" because typically there are no symptoms - it develops silently and painlessly. People can lose bone mass over many years but not know they have osteoporosis until their bones become so weak that a sudden strain, bump or fall causes a hip fracture or a vertebra to collapse. Collapsed vertebra may initially be felt or seen in the form of severe back pain, loss of height, or spinal deformities that result in severely stooped posture.

This disease is assumed to start - often without symptoms - in young adults and progress in women after menopause, when their bone loss accelerates.
