One of my sister's has graves disease(she had to have emergency surgery to remove thyroid-- she was VERY ill at 20 years old-- that was years ago-- she turned into a skeleton in a matter of weeks) and now her daughter has it too. I have another autoimmune thyroid disease-- hashimotos disease.... which is the polar opposite of graves-- but the treatment is often the same... been on thyroid meds almost my whole adult life.(will have to the rest of my life) I never had the weight gain like most get with hypothyroid... but I do get cold VERY easy and I often am depleted of energy.

My sister and niece both had racing heart beat, would get VERY hot and lost so so much weight.... the common symptoms of graves.

Good luck with this-- keep us posted!
