Hi Alice,
I agree with Phyllis's post above. Just wanted to add my two cents, for what it's worth. You didn't say whether your diagnosis of osteopenia was for your spine, your hip, or both. My osteoporosis is at the spine, so I'll just talk about that for now.
Here's a short course on what the numbers mean. Although they measure the densities of four lumbar vertebrae, your official T-score will be the worst one of the four. Assuming 0 is normal bone mass, then -1 is one standard deviation (SD) below normal, -2 is two SDs below normal, etc. Ostepenia is considered anything between -1 and -2.5. Anything under -2.5 is considered osteoporosis. Osteopenia is, as Phyllis said, the precurser to osteoporosis. But just as something pre-cancerous doesn't mean it will become cancer, neither will osteopenia necessarily become osteoporosis. If I were you, I would consider it a wake-up call, to let you know that it's something to watch. It doesn't even mean you're at higher risk for low-trauma fractures, which is ultimately what we fear, right?
My first T-score was -3.0, and I opted not to take Fosamax. Instead, I've been taking Evista, and have improved my BMD to -2.7 in the three years I've been taking it. (I'm 52.)
to the board. I too have thryroid issues, Graves disease (hyperthyroidism). well, I was hyper, but had my thyroid albated (killed off) with radioactive idoine in 2003. I am now on total thryroid replacement and feel just fine. So i have an idea of where you are coming from on that. Thyroid problems both hyper and hypo can be hard on the bones. both too much thryroid and not enough can leach calcium from the bones. Your dr. said you have
