plav,
evenity is probably a sound recommendation. Evenity is a newer anabolic with a black box for cardiac risks. It will be a few years before it becomes clear whether stroke and/or MI are statistical risks. I would avoid the drug until more results are in.
My first drug of choice is Forteo. It gives you fairly rapid protection from vertebral fractures. The second drug choice would be Tymlos.
Forteo, Tymlos and Evenity have to be followed by Reclast (zolendronate) or another bisphosphonate to secure the gains you have with the first drug. Forteo and Tymlos (teriparatide) are usually given for two years. Evenity for one.
I don't think you can regain very much loss with dietary , supplement or exercise changes.
It is good to look at all the pharmaceuticals (there aren't many) because if you have adverse reactions, you want to be ready to change drugs.
If I were only 58 (and female?) I'd consider the low dose estrodial patch.
Physical therapy can be very helpful, just be certain that your PT understands vertebral fragility.
You don't mention calcium, which is maybe part of a good diet. I think recommended calcium amts are too high and contribute to athersclerosis. The medical community remains devided on that issue.
Did you have sacroplasty. Were you tested for secondary causes and were your D levels tested.
D3 and K2 work better together. But they attach to the same receptors for absorption so it is better to take them separately.
Even the endocrinologists who are talkative generally have a set way they want to prescribe. It's best to do your own research and decide for yourself. Then you have to find a willing md. They have the clinical trials and a smaller subset of their own patients. The best part of this site is the wealth of personal experience.
You'll get responses that vary from mine, I hope. And your own decision will be according to what you know about yourself. It really is so interesting. Keep asking anything and everything. Best wishes and congratulations on your semi-retirement.
