FAQ

Are osteoarthritis and osteoporosis the same thing?

No. Although they both contain the term 'osteo', which means bone, they are quite different conditions. Osteoarthritis is a degenerative joint disease and involves deterioration of the joint surfaces (the cartilage covering the ends of the bones), leading to pain and stiffness in the joints. Osteoporosis involves thinning of the bone itself, making it weak, brittle and more likely to fracture.


What is the difference between osteopenia and osteoporosis?

These words are both related to bone loss. The real difference between the two is related to how much bone is actually lost. Osteopenia is when you have had some bone loss but not as much as with osteoporosis. If you have osteopenia, your risk of breaking a bone is increased, but not as much as with osteoporosis. If you have osteopenia you should be talking to your doctor about what you can do to maintain your bone strength and prevent fractures.


Is there any difference between getting your calcium from food or from supplements?

There is no difference in the absorption of calcium from supplements or from food.


Is there any difference between the bisphosphonates Actonel (risedronate) and Fosamax (alendronate)? Do they both have the same effect?

There is no evidence to suggest that there are any significant differences in the treatment effects of alendronate or risedronate. They are very similar in the way they act and in any potential side-effects. The most common side-effect with these medications is mild moderate gastrointestinal discomfort.


How should I take my bisphosphonate and do they interfere with any other medications?

Generally, bisphosphonates should be taken first thing in the morning on an empty stomach with a glass of water. You should remain upright for half an hour after taking them and not eat or drink anything else in that half hour. As well, calcium supplements and oral bisphosphonates should be taken several hours apart. Otherwise the absorption of one can interfere with the other.


How long should I stay on medication for my bones?

Currently, it is unclear how long people should stay on their osteoporosis medications as there is not a lot of data for long term therapy. After every 5 years of treatment with bisphosphonates, it may be appropriate to have 1- 2 years off treatment, monitored by bone densitometry.


I am 50, have rheumatoid arthritis and am on high doses of corticosteroids. What should I do for my bone health?

Generally it is recommended that people commencing corticosteroid therapy for more than 3 months should be placed on a bisphosphonate at the same time to prevent bone loss and fractures. As well, a calcium supplement should also be considered.


I am a 75 year old woman and becoming very hunched over in the top and middle part of my spine ­ do I have osteoporosis or is this just part of ageing?

Changes in your spinal posture as you describe are not just part of ageing. You may have had some 'crush' fractures in your spine that have caused your posture to become like a 'Dowager's hump'. You should definitely see your GP to discuss having a bone density test or spinal x-rays.


I am 48 years old and seem to be going through menopause. Should I have a bone density test to see if I have osteoporosis?

This would depend on whether you have any other major risk factors for osteoporosis, such as a previous fragility fracture or family history. Discuss this with your GP next time you see him/her.


I am 55 and went through menopause about 2 years ago without too many problems. Should I be considering HT to prevent fractures?

HT can prevent bone loss but as it has been associated with a small increased risk in heart disease and breast cancer, it is not recommended for the management of fracture risk alone, as this would mean long-term use.

As well, HT is no longer listed by the TGA as an indication for the treatment and prevention of osteoporosis. The main reason to be prescribed HT these days is for the treatment of menopausal symptoms and this does not seem to be a problem for you.
