My weight remained the same for the two years I was on Forteo. (Which was fine with me.)

Hi - I did the same thing, switched to Forteo after 4 months of Tymlos and, sorry to tell you this, but that extra weight gain came on with a vengeance with Forteo. I'm now up 10 lbs since April. I think Tymlos started the tummy and Forteo added the weight. I have doubled down on my workouts and while I still feel like I'm in a fat suit, I do feel stronger in my bones (if its possible to feel that!) and in my overall muscle strength.
There was a post I saw where a woman said the weight began to melt off after she finished her Forteo, that is my hope! Good luck to you.

I´ve just started with Forteo 5 days ago. No side effects so far but I have no idea about what can happen in the long term. I´ll keep you posted on any possible weight gain, which I hope doesn´t happen in my case. If I experience any weight loss, I´ll be toasting and jumping off happiness, The treatment is annoying and long itself, so weight gain is bollocks even when, of course, bone health is more important. Let me know how are you doing with that when you start. Best wishes.
