TSH/lab question

[Guest guest]

How fast does the TSH shoot up if a person without any thyroid gland

forgets to take one days or even two days dose of Synthroid? I need

to be sure my labs aren't too low so my Doc won't have a hissy-fit.

BTW, he THINKS I'm on Synthroid (he,he!) I'm on the big A.

The half life of T4 is about a week, so missing a dose or two won't

immediately drive the TSH up I would guess. But you're also taking T3,

which has a half life of about a day. I don't know exactly how not

taking the T3 for a couple of days would effect your TSH in the short

term; but I'm under the impression that over all Armour suppresses the

TSH more than T4 alone [corrections anyone???]. Unfortunately if your

doctor is unaware that you're taking T3 he may conclude that you're over

treated and fear that you're hyper [or headed that way] and reduce your

prescription. That is, if he knows [and if I'm right] that T3

suppresses TSH more than T4.

It's probably not too good of an idea to deceive your doctor. Or your

lawyer. If you're having problems that he has not and cannot resolve

it's probably better to try to find another doctor that will work with

you to alleviate your symptoms.
