Re: what does enlarged thyroid glands mean
That's true. If the gland is working too hard - either by trying to make more hormone because your blood levels are too low for you, or by making excess hormone and making your levels too high, it gets larger (goiter).
Anxiety and panic attacks are common thyroid symptoms. Your endo may be mistaken that your blood work is "normal". It might be normal for another person, but not for you in particular.
If you want to post your results with their lab ranges here, we can help you determine if another opinion is a good idea.
