My sister just found out she has hyperthryroidism. Can any of you tell me

i'm sure you already know some of these facts, but its very common in women. There is a name "graves disease", and the old president bush, and his wife barbara both had this. its not because your going to die and go to a grave., but Peter Graves discovered this very odd endocrinology problem. Its hereditary, and you can get a simple thryroid panel done to see if you have it. hypthyroidism is the exact opposite which is even more common.
