Summary
Read the full fact sheet- It is estimated that, on average, women lose up to 10 per cent of their bone mass in the first five years after menopause.
- Osteoporosis is when bones become thinner, causing them to fracture more easily.
- You can reduce your risk of osteoporosis by eating a diet rich in calcium and doing weight-bearing exercise regularly.
- Medical treatments for osteoporosis are available.

What is menopause?
Menopause is when your periods stop. As you approach menopause, your reproductive hormones (e.g. oestrogen) drop. Most women reach menopause between the ages of 45 and 55. In Australia, the average age to reach menopause is 51 to 52.
How does menopause affect bone health?
Bone density starts to decrease with lowered levels of oestrogen around the time of menopause. And it continues to decrease after menopause. Having lower levels of oestrogen increases the risk of developing osteoporosis.
Osteoporosis is a condition where your bones weaken (are less dense), causing them to break or fracture more easily.
On average, women lose up to 10% of their bone mass in the first five years after menopause. After this, the rate of bone loss slows.
About one in two women over the age of 60 will experience at least one fracture due to osteoporosis.
Diagnosing osteoporosis
Osteoporosis is diagnosed using a bone density scan. This is a special X-ray that’s known as a ‘DXA’ or ‘DEXA’ scan. It measures bone density (thickness), usually around the lower spine and upper part of the hip.
A DXA scan gives a T-score that shows if you have:
- normal bone density
- some bone loss (osteopenia)
- lots of bone loss (osteoporosis).
If you are diagnosed with osteoporosis, it’s important to be treated and have regular bone density assessments.
Reducing your risk of osteoporosis
You can reduce your risk of developing osteoporosis by having a healthy lifestyle.
Calcium and vitamin D
Aim to eat about 1,300 mg of calcium every day. This is equal to three to four serves of dairy (e.g. yoghurt). Other good sources of calcium include firm tofu, almonds, Brazil nuts, dark green leafy vegetables, and fish with edible bones (e.g. sardines).
Make sure you have enough vitamin D. Vitamin D helps the body to absorb calcium. It’s made in the skin following sun exposure and is found in very small amounts in some foods. Vitamin D levels can be measured by a simple blood test. Some people may need a vitamin D supplement.
Other lifestyle changes
Try to reduce or stop:
Exercise
Exercise plays an important role in maintaining bone health. It also improves muscle strength, balance and fitness, and reduces the incidence of falls and fractures. It’s recommended you do 30 to 40 minutes of physical activity most days of the week.
Some types of exercise support bone health. For example:
- weight-bearing exercises (e.g. stair walking, skipping, running, tennis, dancing)
- resistance (strength) training (e.g. weight machines, dumbbells, push-ups, squats).
Seek advice from an accredited trainer, exercise physiologist or physiotherapist before starting.
Learn more about exercise for healthy bones on the Healthy Bones Australia website or read the Exercise and Bone Density brochure.
Menopausal hormone therapy (MHT)
If you take MHT soon after menopause (around the age of 50), it can prevent bone loss.
Treatment for osteoporosis
Your doctor may recommend certain medicines or intravenous (IV) infusions and injections.
