Suppressed TsH …

[cazza1001]

HI , I have secondary Hypo and I know I should not be concerned about a suppressed TSH but I cant remember why this isn't a problem . My GP just rang and wants to reduce my Levo immediately - but I've spent 18 months fine tuning the Levo and T3 and finally feel so well - pls can one of you wise ones just give me the technical reasons why suppressed is not a problem with secondary ( pituitary not Thyroid gland issue) - thanks

TSH ( the result is < 0.01 in range of 0.27 - 4.2 ) and both T4 & T3 are in top third of range

Does your GP understand Secondary Hypothyroidism - failure of the pituitary gland to secrete thyroid stimulating hormone (TSH)? It's bound to be low. Also taking T3 tends to lower TSH.

Maybe you could suggest, as he has access to research and articles that you do not, that he reads up on it.

Jeez, they never cease to amaze me with their ignorance of thyroid disease.

The following is from an Expert in hormones:-

TSH is not a thyroid hormone and is not an appropriate guide to thyroid replacement therapy. The hypothalamic-pituitary secretion of TSH did not evolve to tell physicians what dose of levothyroxine a person should swallow every day. A low or suppressed TSH on replacement therapy is not the same thing as a low TSH in primary hyperthyroidism. If you have central hypothyroidism, the TSH will necessarily be low or completely suppressed on T4/T3 therapy; your physician must treat you according to symptoms and the free T4/free T3 levels.
