Hi @serious dooshi has a great point in her reply. If your Dexa has been relatively stable with 30-year treatment of bisphosphonates, evista and holidays (without fractures I assume), that’s a great achievement. Some people with osteoporosis may have a more progressive disease which might be hard to manage well in a span of 30 years.

My take is it’s definitely worth discussing with your endo based on your current Dexa readings as well as your frax risk:
What’s best for your bone going forward - more antiresorptives (bisphosphonates, prolia) or a bone builder (forteo/tymlos vs evenity), since you had been on bisphosphonates for many years;
If an antiresorptive again, your endo’s opinions on the pros and cons for reclast vs prolia.

Getting your endo’s train of thought is important. Getting your own thoughts ready prior to the discussion with your endo. Might need a follow-up meeting shortly after so that you could gather more understanding to discuss more with your endo. That way you are not rushed into making a decision, although it might be better not to wait too long since you are on a holiday from risedronate.

May I ask how many years total you had been on fosamax? And if you don’t mind, what’s your latest P1NP reading?
