A friend of mine had his thyroid removed (killed off with radioactive iodine.) He had Graves disease. He now takes Synthroid since he doesn't have an active thyroid. He seems to be fine, but he still has to be seen every 6 months so that his thyroid dose is regulated.
I have Hashimoto's disease and take Synthroid to regulate my thyroid, but I only go once a year to have my thyroid levels checked.
