Dear Dr. Lupo,
my friend is 2 months after TTE and her latest blood results are TSH 0,03 /0,32-5,0/, FT4 18,77 /10-25/, FT3 FT3 3,6 /4,4-9,3/. She is taking 100 thyroxine. She does not know if she has to lower the dose, because of low TSH. But her FT3 is too low as well.
Thank you.

Looks like the TSH is low suggesting too much replacement, however the other levels do not suggest too much. It depends on the reason for the TTE and the pre-op TSH -- if it was for hyperthyroidism and the TSH was very low before surgery, it may take 4-6 months (or more) before the TSH becomes reliable.
i forgot to write, she had an overactive thyroid prior to the surgery and her TSH was always 0. thank you.
