I have recently been diagosed with hyper. I have tried to get as much information as I can. The information I have read says the treatment currently used in the US is radioactive iodine. This is the treatment my doctor has decide on. My many concern is the side effect to hypo. What is the likely hood that I will become Hypo? Is it better to be hypo than hyper? How can I avoid become hypo? I would like to hear any stories of having hyper. This will help calm my fear. I am scared overall with this disease. I appreciate any responds to my concerns.
