I THINK you are very correct in your theory. Everytime I have high antibodies (-To thyroid-) and I think its my thyroid acting up its not. It is Candida that I have.
It causes me I think , to have high hashi antibodies to thyroid.
I have not had them tested to see if they go back down again. I will check this time though. Its all from the candida I believe.
I do not take any thyroid meds but have to get back on them. I have tried synthroid, Armour. They make me very tired and crappy. I need to try I think - porcine desicated thyroid.
