Blueberry, Synthroid doesn't reduce antibody levels. If it gives any consolation, even if it is Hashi's, the treatment plan isn't really different. You'd still be focusing on TSH levels. It's alarming though because it speaks to her knowledge of the thyroid more generally. In the very least, I'd be prepared to argue that you need a dosage increase.

Solo, I wish I knew the right fix. For some a TSH of 2 might still be too high. Some docs say that 1 closer to normal, but there is some dispute as to how narrow the normal range should be. But you are right to consider other causes. Remind me; is your condition autoimmune related? Sometimes symptoms can worsen when antibody loads go up.
