To answer your first question about what to do if you go hyper again, just like Kimberly said you can go for another round of RAI or get your thyroid surgically removed. I know for me after a little over a year of getting my RAI my thyroid did go hyper again and I did go for another round of it, now im completely hypo. It took around two years of playing with my levothyroxine dose to finally get me into the normal range.
As for your second question about the weight management and exercises, a proper diet is the most important thing you can do to offset the weight gain caused by the thyroid. Even to this day I am struggling to get my BMI down. I have always been a stocky guy but I go to the gym on a daily basis and run 4x a week. While my BMI and weight are not changing my strength, stamina, energy levels are all amazing now. I am running marathons, lifting more weight then ever before and feeling great even tho I am still a bigger guy.
A little about my story, I was diagnosed graves at 18 weighing 180lbs at 5’9″, got my first round of RAI 3 months later weighing 140lbs. Shortly after I shot up to 210lbs, a year later I went hyper again and dropped to 170lbs, I received my second round of RAI and now I am 230lbs but in the best shape of my life. So even tho I can’t get the crazy six pack and I’m big, the key is to keep at the diet and exercise but have fun with it and you will see great results.
Good luck and remember your not alone in this.
