Graves disease vs. Hyperthyroidism

Andrea
So my Dr called me today telling me that I have hyperthyroidism/graves disease. He gave me some meds for it, and all that stuff. When I look over the symptoms though, hardly any of them apply. I'm overweight so the weight loss thing associated with them don't apply. Can anyone offer some insight regarding this before I fry my thyroid with meds or radioactive iodine???
