@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.

I believe that while taking the bone drugs your density improves but when you stop it makes your bones worse. You cannot be on one drug forever, so they try all different ones. I took oral Boniva for 2 years, -2.5 spine. Five years later my dexa says my spine has not changed and my hip improved from -2.3 to -1.9. However, my REMS test a few months before the dexa of 2025, said my spine is -2.9 and hip -2.7. The good news my quality of bone is excellent and it puts me at a 5 years risk of only 3% fracture. Which one to believe? I see an internist and a functional medical doctors. Both said not to go on any drugs. I have gone to OsteoStrong for 5 years, lift weights 3-4 times a week (heavy) and walk 5 mi a day. On HRT, of course eat correctly and right supplementation. I also have a lymphatic plate at home. I am believing in faith to apply a whole body approach without drugs. No judgement on anyone else because are bodies are so different. Boniva gave me mild esophagus problems. The best advise is weight train.
