回複：求教關於骨質疏鬆。。。

Thank you so much. She does take calcium plus V-D. It seems there are two stages of this disease---osteopedia at the first stage and osteoporousis later on .But what is the dividing line, say, t score -2, or t score -2.5? I really am eager to know about this score to keep track of its development.

BTW, what is calcitonin treatment?
Your answer is very much appreciated.
