Why do people with osteoporosis so often break bones?

This condition results in a reduction in the bone mass per unit volume. The end result of the disease is bones that are thinner and more brittle than those of people who do not have the disease. This low bone mass leads to loss of the normal bone architecture, which leads to deterioration of the tissue of the bone and so to the fragility of the bones. This makes people susceptible to bone fractures, especially hips, as this is a major weight-bearing bone in the human skeleton.
