Hypothyroidism

[aer_vlad]

My TSH was normal, yet my T3 was very low, T4 was low normal (I can go dig up the labs if you would like?).

I'm taking Synthroid (levothyroxine), which is synthetic T4. From what I gather, the higher T4 levels provides easier convertibility to T3 (as the body requires it). There are arguments for Amour (natural T3/T4 combo), but for my situation, Synthroid has raised my T3 levels and I feel much, much better (not freezing all the time).

What does your doctor say? Because you're "low normal," s/he won't prescribe you treatment?

My current Dr will. She is actually a opening minded shrink (for my ADD meds) that is willing to handle my HRT as well. The big issue is that the t3/t4 issue and underlying issues are not appreciated because Drs often treat blood work and do not consider the bigger picture (ie is low normal really where someone should be??).

The difference in how the t3 and t4 numbers between people is a little complex too. For instance I am low t3 and high t4; you are low t3 and low normal t4.
