The body is always growing bone but the imbalance comes when the bone being broken down exceeds the bone growth. The goal as I understand it from my endocrinologist’s explanation, is to get the process in balance, she chose to do this by slowing the breakdown process. And I’m not sure but my guess is that, if this is not sufficient, she would then turn to a bone growth drug. I have read that certain osteoporosis drugs grow bone on the outside of the bone rather than the center and that this kind of bone growth does little to keep bones from fracturing because it does not increase bone strength but it does show up in a Dexa scan as more bone. My knowledge ends here but I will try to do some research to find out why my endocrinologist (who trains other docs in how to treat osteoporosis) chose to use a drug that limits reabsorption as the first line of defense (maybe the body makes better bone than the drugs do?). If anyone can answer this question please chime in!
