@babs10 I agree, but it has been a struggle for me to convince my doctor to let me take any tests beyond the BMD and standard blood work (even though I am paying for most of them) but she has reluctantly consented on a few (I ask for them one at a time in order of priority to increase my chances of getting one and thank her when she does...it has mostly worked so far but it is frustrating). She has no interest in finding a root cause. I am in Ottawa, Canada and many people can't get a family doctor here due to shortages so switching doctors is impossible. We have naturopaths which I believe are the closest thing to the US functional medicine doctors, but there doesn't seem to be much expertise in osteoporosis, and they are not covered unless you have private insurance (which luckily I have). This site has been extremely helpful...so glad I found it!
