@ppat4pr your chiropractor is right about bisphosphonates and Prolia over time, though they are pretty safe for certain periods of time and do increase bone density. These drugs work by reducing bone turnover (anti-resorptive) so yes, there is a risk of aytpical femur fracture over time.

However your chiropractor is wrong about Forteo and Tymlos, which build quality bone (anabolics, working through the parathyroid).

Evenity builds bone the first 6 months and is anti-resorptive for the last 6 months. It works by inhibiting sclerostin and has a lower risk than bisphosponates.

The problem with Prolia is risk of fracture when you get off, unless you transition to Reclast.
