Why would my TSH be below range and yet at same time my T4/T3 is also below mid-range? If my TSH was so low, I'd expect either T4 or T3 to be in upper range. I am taking T4/T3 combo, so I understand why TSH and T4 is low, but at the very least, shouldn't T3 be in upper range?
At the time of the tests below I was on 125mcg T4, 10mcg T3 x 2 daily. Let's say 20-25mcg of liothyronine is equiv to approx 100mcg of levo, so theoretically I'm taking equivalent of 200-225mcg of levo.
I understand why T4 is not high because my system senses the presence of T3 and therefore excretes excess T4.
However why has this dose not increased my T3 levels to upper range?
Assuming I need my T3 in upper range, is it my relatively low T3 that continues to make me feel unwell?
Is increasing T3 and lowering T4 the answer?
