Is there a guideline that says only women under 50 get osteoporosis after surgical meno.& arimidex (anastrozole) as thats what my dr thought now my bnes are ruined.

Bone loss: Aromatase inhibitor may cause bone loss. That is why it is important to have a baseline bone desitometry to check you bone density. In addition, while you are on aromatase inhibitor, there is a medication that you can get to prevent bone loss/decrease skeletal related event- like denosumab/prolia. Other bisphosphonate therapy also can be your option if you have osteoporosis.
