What is osteoporosis?

Osteoporosis is a bone disease where bones have a low mass or density. Usually it is caused by an increased breakdown of bone tissue. This leads to bones becoming more fragile, which increases the risk of the bones breaking. Sites that are particularly prone to breaking when someone has osteoporosis include the hip, spine, shoulder and wrist.

Osteoporosis is often known as “the silent thief” because the loss of bone happens without any symptoms.
