Babs10, I know that feeling. It's a warning that you are getting ready to roll.

I'm familiar with the idea that Tymlos is more effective at raising dxa bone density numbers for both hip and femur than Forteo. Greater porosity with Forteo may reflect greater resilience. Lower density in cortical bone can yield on impact rather than break.
I'm curious about the concept that teripartide can make osteoporosis worse. I think the MDs in the video (I haven't seen) meant geater porosity so less density with Forteo compared to Tymlos. Density and strength are not the same measurement.
Patients can lose bone density while on Forteo because of unresolved cause ( like hyperparathyroidism), when medical providers fail to screen for secondary causes of osteoporosis.
