HELLO, I HAD A THYROIDECTOMY IN AUGUST OF 08', I HAVE TESTED MY TPO LEVELS 2 TIMES SINCE THE FIRST TIME THE LEVELS CAME BACK LOWER THAN PRE THYROIDECTOMY, AND THE MOST RECENT TPO LEVELS HAVE COME BACK ELEVATED. MY QUESTION IS HOW LONG DOES IT TAKE FOR THE TPO LEVELS TO DROP? I KNOW THERE IS A DISEASE THAT GOES ALON WITH HASHIMOTOS THYROIDITIS CALLED HASHIMOTOS ENCEPHALOPATHY, I AM CURRENTLY TRYING TO ELIMINATE THIS.
