If they told you you have a goiter or something and need something removed..don't do it. It will mess you up way more than you know. Just look into Iodine and fixing it on it's own.
Hypothyroidism has a number of causes including hypothalamic, pituitary or adrenal dysfunction, chlorine, fluorine or bromine exposure, hormone issues, poor T4 to T3 conversion, high rT3, autoimmunity, etc. Iodine will not address all forms of hypothyroidism.
