Osteoporosis is a skeletal disease characterised by low bone mass and microarchitectural deterioration with a resulting increase in bone fragility and therefore increased risk of fracture[1]. It occurs predominantly in postmenopausal women and in patients who are taking long-term oral corticosteroids (glucocorticosteroids)[2]. Other factors which increase the risk of developing osteoporosis are low body weight, cigarette smoking, excess alcohol intake, lack of physical activity, family history of osteoporosis and early menopause.
