Osteoporosis
Osteoporosis is the term used to describe the condition where the bones particularly those of the spine, wrist, ankle and hips become thin and weak through the progressive loss of minerals, mass and density, and are prone to break easily.
The bones become porous and brittle and often there are no warning signs before a break occurs. The condition is caused because more bone cells are lost than replaced, so bone density decreases.
It mainly affects women after the age of the menopause, although men can have it.
