prone to fracture any time. If this disease is not cured the end result
is fractured bones, normally bones at places like hip, spine, wrist,
ankle.
In this disease
-
Bone mineral
density (BMD) is reduced
-
Bone micro
architecture is disrupted
-
Nonn-collagenous
proteins is altered
Prevention

What factors determine bone strength?
More bone mass
(bone density) - the stronger the bone. It is influenced by genetic
factors, environmental factors and medicines. Men have greater bone
density than women. Afro-Americans have a higher bone density than white
or Asian Americans.
Bone density accumulates till the age of 25 from childhood and
maintained a decade. Then 0.3% to 0.5% of their bone mass per year is
reduced as part of the aging process.
Estrogen is important for maintaining bone density in women. When rates
decline of estrogen After menopause estrogen levels decrease and bone
loss accelerates.
