What is osteoporosis and why do I need treatment?

You have been prescribed Evenity because you are at increased risk of another fracture due to osteoporosis

What happens to your bones when you have osteoporosis:

  • Osteoporosis is a long-term bone disease that occurs when your body loses too much bone and/or makes too little bone
  • When the balance of bone loss exceeds renewed bone formation, they lose their density
  • When bones lose their density, they become thin and fragile and are more likely to break
  • Osteoporosis literally means ‘porous bones’. It is often called a ‘silent’ disease because you tend not to know that you have osteoporosis until you suffer a fragility fracture

What is a fragility fracture?

(A fracture due to weak bones)

Every person's experience is different when it comes to fragility fractures, but there is a common reason as to why they occur: low bone mineral density (BMD) and a fragile skeleton due to osteoporosis. Fragility fractures are caused by minor trauma such as a fall from standing height. 

Fragility fractures may lead to long-term issues that can impact your independence, such as:

  • Chronic back pain
  • Kyphosis- a curvature of the spine associated with loss of height that may happen due to fractures in the spine
  • Difficulty walking after fractures in the hip

Fragility fractures relating to osteoporosis occur most frequently in the sites illustrated.

Exercises that are beneficial for your posture and balance include pilates, tai chi and yoga.

What is kyphosis?

Kyphosis is curvature of the spine that causes the top of the back to appear more rounded than normal. Everyone has some degree of curvature in their spine. However, a curve of more than 45 degrees is considered excessive. 

Sometimes kyphosis doesn't cause any symptoms other than the back appearing abnormally curved or hunched. However, in some cases the condition may cause back pain, stiffness, tenderness of the spine, and tiredness.

Back pain can be particularly problematic in adults with kyphosis because the body has to compensate for the spinal abnormality. If you have severe kyphosis, your symptoms may get worse over time. You may also have difficulty breathing and eating. Kyphosis may develop, among other causes, because of spinal injuries, such as vertebral fractures caused by osteoporosis.

Exercise may help by strengthening the muscles in the back. Ask your doctor which exercises may be appropriate for you.

What should I know about measuring bone strength?

Bone Mineral Density

Your bone is mainly made of minerals. These minerals are what makes bones hard, and make up the internal structure. The content of mineral in your bones is often referred to as BMD.

We all lose bone density as we get older, and this is why osteoporosis is more common in later life. However, osteoporosis is NOT a normal part of ageing. A measurement called T-score is used to assess if you have osteoporosis.

Your healthcare professional may arrange tests, such as dual X-ray absorptiometry (DEXA or DXA) scan, which measures the density of your bone to estimate your bone strength.
