This test is done to measure the density of bones and this is able to predict the risk of fractures. Bone density decreases in both men and women with age, but in women, the decrease is more rapid and more severe following menopause when the ovaries stop producing the oestrogen hormone. BMD testing can show whether there is significant bone loss, resulting in low bone mass. This is a major cause of osteoporosis and of bone fractures (particularly the hip, spine or forearm) in men and women over the age of 40.
Osteoporosis is a reduction in the amount of bone mass resulting in the loss of bone strength. This will predispose it to fracture. Osteopenia refers to a decrease in bone mineral density and is less severe form compared to osteoporosis. Eventually, it is likely to lead to osteoporosis if no treatment is given.
