Yes, Dexa isn't the whole picture. Have you lost height? If not, that is a very good sign. Are you taking natural calcium (e.g. milk)? My specialist prefers that to tablets. No weight-bearing exercise is an issue. However, the whole is more than the sum of its parts and if you ever stop Prolia, you have a rebound of bone loss. If stopping it is unlikely, then that is not an issue. I am wondering why you don't also consider bisphosphates. They also effective in that French study, unless I am missing something.
