Hi there,
I had Graves Disease around 1984-5 and had my Thyroid Gland removed via Radio Active Isotope. I was not planning on having any more children (Doc's question) and therefore it was safe and appropriate for me to have the removal via this method. The after effect of the radiation was a little uncomfortable (night sweats, heart POUNDING...hard enough to wake me up, and that was short lived and just about all of the symptoms). My eyes were just beginning to bulge a little bit, and they went back to normal soon.
I was advised to stay away from pregnant women and small children for a few weeks.
Now, I realize that your question is more about the loss of the gland.
A blood test and follow up exam by your Endocrinologist is necessary to get the correct dosage of medication. The only problem I have ever had was when I asked a new Doc to give me a prescription for a refill, he needed a blood test (reasonable request), and when the results came back he told me my thyroid level was normal & I didn't need to take meds. I told him I didn't have a thyroid, but he said that was ok.....and of course, he had on his white GOD jacket so I believed him.......Several weeks later I was feeling so bad that I had a friend that I worked with drive me to my (new) Endocrinologist's office. When I explained the situation to him, he called the Dr. and chewed him out. He then explained to me that I was on the verge of going into a coma and that I should NEVER listen to any Doc telling me I didn't need this medication. He returned me to my normal, healthy state after several weeks of blood tests and med. increases until I was back to the best level.
Once a year I have a blood test and meds adjustment if necessary, which after getting stabilized changes were few and far between.
I think the method of removal/destruction of my thyroid was the best method for me.....no down time, very little time lost from work, no scar, therefore no recovery from surgery, no hospital time, therefore less expensive.
I hope this (long winded) message helps you. Good luck!
