@goseve I have maintained my Forteo gains and possibly even gained density on HRT as my most recent Dexa was -2.5, showing an increase from the last 7ish years of a steady -2.9. My Dexa was done on a new machine and coupled with the fact that I have arthritis (which can imitate increased bone density), I take these numbers with a grain of salt. But I'll take them happily and with a hopeful belief that they are accurate! HRT has definitely helped me maintain my Forteo gains but I also do a whole lot of work. Daily exercise is a half hour of core strengthening plus either a high energy dance class or weights at the gym. In addition, I have a whole foods, gluten free diet and calculate my nutrition on Cronometer to make sure I meet my daily nutrient goals. I no longer take calcium supplements due the potential risk of calcifications of the arteries and meet my needs with food. It's hard and attentive work but worth it, not just for bones but for general health. I wish you all the best!
