| i don't think osteopenia and osteoporosis are that different?
isn't osteopenia like an early form/precursor to osteoporosis? (although not everyone with the first will get the second)
from web md:
"Osteopenia refers to bone mineral density (BMD) that is lower than normal peak BMD but not low enough to be classified as osteoporosis. Bone mineral density is a measurement of the level of minerals in the bones, which indicates how dense and strong they are. If your BMD is low compared to normal peak BMD, you are said to have osteopenia. Having osteopenia means there is a greater risk that, as time passes, you may develop BMD that is very low compared to normal, known as osteoporosis."
also, more specifically,
"Within 1 standard deviation of the mean in either direction is considered normal. A bone density within the range of 1 to 2.5 standard deviations below the mean is defined as osteopenia, and greater than 2.5 standard deviations below the mean is osteoporosis."
that's the definition i've always known
have you got a link for the misshapen bones thing? i'm wondering whether it's paget's disease of the bone you're thinking of. that does cause misshapen and weakened bones, although technically they're enlarged and that causes the weakness. it's odd but interesting (and surprisingly common) |
