Once bone mass is lost, it can never be
regained.
Both genetic and environmental factors
play a lifelong role in a person's bone
density.
Bone density loss is a genetic factor
and can not be controlled by changes in
a person's lifestyle.
Women should carefully monitor their
diet and avoid alcohol and cigarettes in
order to maintain bone mass.
