Preventing Broken Bones
Even though healthy bones are very strong, any bone will
break if the force applied against it is great enough. Bones that are weakened
by disease or misuse may break more easily than healthy bones. To develop and
maintain healthy bones, a person needs adequate amounts of calcium and proper
exercise.
Because of the way bones are made, calcium is very important
in the growth, development, and maintenance of strong bones. Adequate amounts
of calcium are necessary as a child grows and for the adult as well. Women, in
particular, must have enough calcium in their diet. The female hormone estrogen
regulates the use of calcium in women's bodies. Following menopause, when women
produce far less estrogen, calcium regulation is more difficult. So it is very
important that women make their bones as strong as possible before menopause,
through weight-beating exercise and adequate calcium in their diets. In some
women after menopause, bones fracture very easily because they have been
weakened by calcium depletion.
Because of the way bones are made, they also get stronger
with regular but not excessive exercise. If a person is active, bones will
become stronger and more dense. The bones of an inactive person are often not
as strong and may fracture more easily than those of an active person. For this
reason, older people should try to remain physically active.
Proper diet and exercise, along with an understanding of
what bones are made of and how they break, may help in preventing some
fractures.
