Re: what does a very low TSH level mean?

You need to get your FT3 levels checked as well to get a better diagnosis.

I've recently been reading that if your FT3 and FT4 are balanced, but your TSH is still low, you could have elevated cortisol levels. I was tested a few weeks ago for adrenal fatigue, but found out I'm at the stage where my cortisol levels are elevated throughout the entire day, and that can suppress your TSH.

Re: what does a very low TSH level mean?

My TSH Level is 0.01, Free T4 is 0.60 and my Free T3 is 3.25. Is there anyone with similar levels who can help me to understand how they are coping with thyroid disease.

I have had below-range TSH ever since I was Dx'd with Graves' disease, thanks to the Graves' antibodies.

I still have my thyroid and developed debilitating hypo symptoms with mid-range FT4/FT3 yet my TSH was still below-range.

Knowledgeable doctors treat thyroid disease based on the actual thyroid hormone levels - the FreeT4 and FreeT3.

Since your FreeT4 level is SO low, I'd be looking at starting levothyroxine.

I agree that you need to get your FreeT3 checked.

TSH is not a reliable indicator of thyroid function....and, yes, you might have some adrenal/pituitary issues going on that can cause the low TSH but, if you have symptoms of hypothyroidism and a FreeT3 level below mid-range, you just might want to try a little T3.

Re: what does a very low TSH level mean?

You know, some symptoms of hypothyroidism and hyperthyroidism are very similar.

That FreeT3 test should help fill in the blanks 'cuz, if it's high, you just might be developing hyperthyroidism.

Re: what does a very low TSH level mean?

I'd suggest that you check out Stop The Thyroid Madness.

They cover just about all the different possibilities.

In truth, TSH is not really an indicator of Thyroid function, it's really more of an indication of pituitary.

TSH is secreeted by the pituitary, which secreets it when you're not getting enough thyroid hormones. If your pituitary isn't functioning correctly (which often happens when your thyroid or adrenals aren't functioning correctly), it could show up, or it could just not be an indicator whatsoever.

Before.. I believe it was 1968.. doctors didn't diagnose based on blood work. They diagnosed hypothyroidism by symptom. Since the invention of the blood test, everything is screwy.
