This is a paper which might be complicated for us non-medical but this extract informs us that our FT3 should be at the level it was previous to thyroidectomy (I wonder if it was done). In any even I should think her FT3 should be towards the upper end of the range for her to feel good. I have a thyroid gland but I am best when I take T3 only rather than levothyroxine which made me more unwell than before being diagnosed as hypo. (I assume L-T4 is the combination of liothyronine(T3) and T4 (levothyroxine).
In conclusion, this study showed that moderate TSH-
suppressive doses of
L-T 4 were required for postoperative athyreotic patients to achieve their preoperative native serum FT
3 levels. They must take L
-T 4 for the remainder of their lives. Therefore, even if thyroidal dysfunction may be subtle, its long-term effects cannot be over- looked. The question arises as to which of two patient groups is in euthyroid condition: those with normal serum TSH levels and mildly low FT
3 or those with serum FT
3 levels equivalent to their preoperative native serum FT
3 levels and mildly suppressed TSH.
An animal study has shown that
L-T4 alone administered to thyroidectomized rats at doses to normalize plasma TSH levels does not normalize T
3 contents in some tissues
Prospective, properly designed studies
including well-being or a metabolic marker such as
lipid or bone are needed to clarify the best method of
managing thyroid function in postoperative athyreotic
