Osteoporosis

Osteoporosis

Green arrow pointing to subject menu What is osteoporosis?

Osteoporosis is a condition where the bones become fragile and brittle, and can fracture more easily than normal bones. Even minor falls can cause serious fractures. 1 in 2 women and 1 in 3 men over 60 will have a fracture due to osteoporosis.

Osteoporosis and fractures are major causes of injury, long term disability and even death in older Australians.

Green arrow pointing to subject menu How common is osteoporosis?

The incidence of osteoporosis is increasing, primarily as people live longer and the population ages.

  • It is predicted that by 2010, 1 in 3 hospital beds will be occupied by elderly women with fractures (Dubbo Osteoporosis Epidemiology Study)
  • It has been calculated that by 2011, hip fractures in Australia will have increased by 83% (National Research Institute of Gerontology and Geriatric Medicine, Melbourne).

Green arrow pointing to subject menu What causes osteoporosis?

Osteoporosis is different from most other diseases or common illnesses in that there is no one single cause. The overall health of a person’s bones is determined by:

• Your genes
• Nutrition (especially calcium and vitamin D)
• Hormonal activity
• Exercise

These factors determine how well the bones form in early adulthood (peak bone mass). After this, prevention of bone loss becomes the most important.

Anything, which leads to decreased formation of bone early in life, or loss of bone structure later in life, may lead to osteoporosis and fragile bones, which can then fracture.

Green arrow pointing to subject menu Preventing osteoporosis

Osteoporosis is largely preventable for many people. Prevention of this disease is very important because, while there are treatments for osteoporosis, there is currently no cure. There are several steps to prevent osteoporosis. No one step alone is enough to prevent osteoporosis but in combination they will all help.

These steps include:

  • A balanced diet rich in calcium and vitamin D
  • Weight-bearing and strengtheneng exercises
  • Undertake a moderate, regular exercise program and stick with it
  • Bone density testing and medications when appropriate
  • Stop smoking
  • Get proper amounts of calcium generally recommended to be 1000 to 1500 mg/day for postmenopausal women
  • Limit alcohol intake
  • Women should discuss oestrogen replacement with their physicians where appropriate
  • Vitamin D is needed for the body to absorb calcium. 400-800 IU per day is recommended. Direct exposure to sunlight (during winter), fortified dairy products, egg yolks, saltwater fish and cod liver oil are good sources.
