T4 - T3 and parasites.

[Guest guest]

Dear Celeste.

You email has been very useful for me. I appreciate your

response and teaching very, very much !!

I have some more questions

1) Is there any chance that a healthy person produces T4

but not T3 ??

2) If liver is not working well, is T3 produced in sub-normal quantities ?

3) What about if bowels have parasites ? does this condition avoid

thyroides from producing T 4 ??

You answer is very much welcome and apprecaited.

Osvaldo
