Low T4 a Problem? (TISH)

[Guest guest]

Hi fellow Chocaholics,

I am hypo with Hashi's and use Armour 150 (2.5 grains) plus cytomel for

added T3. So my dose would be considered high by a typical MD but normal

for many of you on the list....equal to about 3.5 grains.

My recent labs showed a low T4 level of: .91 (.61 - 1.76)

a low TSH level of: .03 (.35 - 5.5)

and a medium T3 level of 3.3 (2.3 - 4.2)

As you can see, I need the extra cytomel to boost the T3 level up to the

midpoint of the range. That's why I supplement the Armour this way. I have

no hyper symptoms and sometimes feel a little hypo but nowhere like I used

to feel on Synthroid alone!!

My question is concerning the T4 being low: how can it affect me? As long

as it is in the normal range and the more active agent (T3) is adequate,

won't I be okay? What independent contribution does T4 make to our

health? When a person takes a lot of T3 (like I do) can that push T4

downward? Would I better off taking 3+ grains of Armour instead of 2.5

plus cytomel, in order to push my T4 up higher?
