@bleaves I hope you have a doctor who can explain things because there is a lot of old or incorrect information online.

It is important to note that Tymlos and Forteo do not cause bones to become "brittle." Bisphosphonates and Prolia, and to a lesser extent Evenity, may have this effect but over a long period of time and more often for cancer patients on high doses.

The bones, in my experience, don't "shatter." Spinal fractures involve a collapse of the vertebrae, from mild to severe. The hip can break. With severe osteoporosis- and I know this from personal experience, it doesn't take a fall to have a fracture. And fractures are more likely if you have serious bone loss and don't take meds!
