I see an anti-aging physician who warned me years ago to refuse medications (like Boniva) because studies have shown that while it prevents breakdown of bone to some degree, its secondary result is the prevention of bone building. He underlined that the break-down/buildup process is quite a natural process that your body has been doing from the get-go. When the meds interfere with this process, one is left with old, increasingly porous bone which is more likely to break. Sorry for that bad news, but I would think that under the circumstances, you have done well to maintain. My internist, of course, was pushing the meds and the calcium tabs b/c he said I had osteopenia -- however, eating as I do now and w/o their meds, I was told on the last scan (over a year ago) that the osteopenia was gone. I'll have a follow-up this summer and will see how that looks. Wish I had #s to give you, but will ask on the repeat test.
