@lynn59 "8 months research", so I was unknowingly preaching to the choir on doing research!

As to your doc and her DXA comments I have no idea what she meant about accuracy and frequency. As accurate as what? I could make guesses but not much point in that. I have seen nothing emerging in the literature or talked about in forums to indicate DXA s are no longer thought to be valuable. I do acknowledge that DXA scans are not as accurate as we want them to be. That is unfortunate and frustrating but not using them because they are imperfect is illogical, at least until you have a better replacement to offer.

Many times large scale public policy recommendations are based on measures that do not reflect their worth to an individual. In other words factors like the money the insurance companies or governments would have to spend short term may be a huge factor in the recommendations. Personally I'm getting scans every year (and once even sooner) until I get my bone loss under control. I can make use of that information even though it may be imperfect. And finally a large percentage of all the research on drugs, exercise and other factors influencing bone loss (or gain) is done using DXA scans. And those DXA scans in research are often done at shorter intervals than 2 years. Certainly down to 6-8 months. Those scans done at those more frequent intervals are how we know a lot about how well drugs perform or whether or not this style or that style of exercise is more beneficial to our bones.

Personally I would have anxiety from her recommendations because they don't match what I consider best practice or what's most logical. Following a course of treatment with daily injections for 2 years with no attempt to determine if it's helping, that to me is sheer lunacy.

I acknowledge that some doctors who are considered osteoporosis experts practice that way. Just doesn't make sense to me.
Best of luck with your decisions
