Osteoporosis is a common disease in Australia with 1.2 million people estimated to have osteoporosis and a further 6.3 million with low bone density. This disease makes bones become more brittle leading to a higher risk of breaks than in normal bone and is caused when the bones lose minerals (such as calcium) more quickly than the body can replace them leading to a loss of bone thickness and density.
“The Silent Disease”
Osteoporosis usually has no symptoms until a fracture occurs, which is why it is often known as “the silent disease.” Osteoporosis can occur in any bone, but is commonly found in the wrist, spine and hip. Fractures in the spine as a result of osteoporosis can result in height loss and changes in posture.
