@kathleen1314 Wow. I am so grateful for this information. I have been on various meds over the decades. My Dexas are low. But not frightening so. My PCP wants me to start Prolia. I have reg D and Calcium tests. Both say normal so I am suspect of the tests’ ability to detect metabolism and absorption. I need to decide about the meds and this information is soooo helpful going forward. Thank you! 🙂
