I am in the same boat. I was diagnosed with Grave’s Disease 7 years ago after my second pregnancy and now am 100 lbs overweight. Nothing I have tried to help me lose the wieght works. I have been pregnant 3 times since my diagnoses and will usually go into "remission" during the pregnancy but Grave’s reappears about 4 months after delivery. And with each pregnancy I had gain weight and kept in on. I am just as frustrated with this and am actually considering RAI to see if I can lose weight while dealing with HYPO issues instead of HYPRE issues. Good Luck!!
