Osteoporosis is a progressive decrease in bone mass that makes bones more fragile and prone to fractures.

The body requires an adequate supply of minerals such as calcium to maintain the density, and strength to the bones
The body also needs a proper intake of vitamin D to absorb calcium from food and incorporate it into the bones.
At around 30 years of age bones stop growing, then begin to decrease slowly.
When there is a significant reduction in bone density, pains and deformities start showing up and fractures heal slowly.
A fracture can be diagnosed by densitometry, a test that measures bone density.
The treatment is to maintain / increase bone density is based on an adequate amount of calcium consumption and practice exercises.
