Estrogen can cause more thyroid hormones
to bind
to protein and become useless
to cells. I just noticed that
in her labs from 11/13, TT3 is well over range, but by 5/14, FT3 (FT3 is the unbound portion of TT3) is very low in the range. Back in 3/13, TT3 was low, so it's kind of all over the place. Of course, there's also 14 months time in there.
Has anyone ever tested your daughter for thyroid antibodies?
