Re: Reasons for low TSH, free T4 and free T3 - was Moan about doctor

Thanks, Sheila, but I imagine the suppressed TSH is caused by the fact that I

have been on Thyroid-s for a while, not for any more sinister reason. I did ask

the doctor whether the pituitary could be sluggish, but she dismissed the idea.

Hi Miriam, this is what concerns me, TSH would be suppressed by

using T3, but when you are taking natural desiccated thyroid extract which also

contains T4, T3, T2 and T1, your free T3 should be right at the top of the

reference range, and your free T4 would be just above the middle of the

reference range but both are below the very bottom of their respective ranges -

this is why I have suggested there may be a pituitary problem. The reason we

ask members to stop their thyroid hormone replacement the morning they have

their thyroid function tested is because the T3 level would show so high, the

doctor would try to make the patient reduce their dose or even to stop it

altogether. By not taking any the morning of the test, it has had time to

settle down and not scare the doctor.

I think you have your mind set on your low TSH being caused

because you are taking Thyroid-s - but your other results are not consistent

with this.

No, my mind isn't set on anything, so don't worry about that. I am still

waiting for feedback from Dr P in any case. Thankfully I am not dependent on

the doctor who ran the blood test for me.

I think the reason my Free T3 and Free T4 are not very high is that I am

actually not taking very much Thyroid-s. My pulse and blood pressure go too

high if I take more than a little. This is another issue I have asked Dr P

about. Whether the TSH could be suppressed at a dose where the Free T3 and Free

T4 are not boosted much is a matter I need more expert advice about.
