Introduction:
Osteoporosis
is a disease of bone in which the bone mineral density is reduced
and the bones are more susceptible to fracture. Osteoporosis is
best described as "porous bones".
Bones
are living tissue, constantly being rebuilt. With osteoporosis,
the rate of bone loss is greater than that of bone rebuilding,
causing thin, porous bones that break easily.
More
than 28 million Americans have osteoporosis or are at high risk of
developing it. |
