@fsf I'm 77 years of age and still somewhat active. I have seen both a rheumatologist and my regular endo for diagnosed osteoporosis.. The rheumatologist was not very helpful but the endo, who treats me for other conditions, was thorough. She ordered various bloodtests and most recently the calcium urine test. She prescribed Tymlos at my request (the rheumatologist did not despite a -3.2 wrist reading on the DEXA scan) and the endo is monitoring the Tymlos results on an intermittent basis. I believe the doctor experience will differ from doctor to doctor and a good course of action is to reach for 2d and/or 3d opinions. As a lifelong athlete myself, former marathon runner, I've had my share of injuries and conflicting medical opinions. Find someone you trust and do online research on non-sponsored sites. I never thought I would develop osteoporosis and I should have known better with my thin body frame. Now I'm doing a number of things to counteract (weight training, various supplements including leucine and increased protein intake, anabolic injections). I have not tried HRT due to family history. This website is an excellent source of information. Best of luck!
