Osteoporosis and osteopaenia

Healthy bones help you stay mobile and independent. It’s never too early to look after your bones and reduce the risk of osteoporosis.

Learn more about osteoporosis and osteopaenia, including common risk factors.

Osteoporosis

Osteoporosis is when bones lose their density and become thin, weak and fragile. This makes them more at risk of fracture, even from something as simple as a minor bump. Often there are no signs or symptoms of osteoporosis until a fracture occurs.

Any bone can be affected by osteoporosis, but the most common sites are:

  • hip
  • spine
  • wrist
  • ribs
  • pelvis
  • upper arm.

The older you get, the greater the risk of osteoporosis. In Australia, it’s estimated that 23% of women over 50 have osteoporosis.

Risk factors include:

  • family history
  • low calcium intake
  • low vitamin D levels
  • low levels of physical activity
  • smoking
  • high alcohol intake.

Other risk factors include:

  • early or premature menopause
  • certain medicines (e.g. warfarin, thyroid hormone)
  • some medical conditions (e.g. coeliac disease, inflammatory bowel disease, diabetes, thyroid conditions, rheumatoid arthritis, anorexia nervosa)
  • breaking a bone when you’re over 50.

Osteopaenia

Osteopaenia is when you have lower bone density, but not low enough to be classified as osteoporosis. If you have osteopaenia your risk of breaking a bone is higher than normal, but not as high as it is with osteoporosis.

Treatments

If you have been diagnosed with osteoporosis or osteopaenia, it’s important to follow your doctor’s recommendations about exercise and calcium and vitamin D intake.
