Would like an opinion on my TSH and Free T4 levels

Postby cawpcat » Thu Sep 10, 2009 10:31 am

I've been seeing an endocrinologist for a few years after my TSH levels dipped low during my 2nd pregnancy. After I had my baby, the numbers went back up a little, but ended back up in the normal range. My TSH levels are now usually around 0.63 and my Free T4 came out to be 0.67 (for both, it says the range is 0.4 - 4.5). I have an enlarged thryoid gland (goiter) and have typical symptoms of hypothyroidism, yet my doctor says everything is fine. I don't feel fine.

I'm concerned that even though the TSH and FT4 levels are considered "normal", aren't they a wee bit low? For them both to be lower like that, it makes me wonder if I have a pituitary gland issue? I'm planning to see a new endocrinologist eventually to get another opinion, but wanted to throw it out here to get your thoughts. Thanks in advance for any input!

At the present time, as the values (although on the lower side of the laboratory reference range) are within 'normal' - a doctor naturally would consider it as such - unless the clinical picture is compelling one way or the other.

Is your T3 value known? If so, please let us know.This may help us to answer your question better.

If it happens to be low, then non thyroidal illness is more likely (or, very rarely, secondary hpothyroidism).

good luck!
