Bumping an old thread. I have just been diagnosed with Graves disease, and in less than 3 weeks my endurance and strength have plummetted down to 20% of what it used to be. It is completely dishearting.
I'm seeing the doc tomorrow for a decision on the treatment. For those who have been through this, does your fitness level return to where it was before? It has ade me very anxious.

Thanks a lot.
