Re: TSH has dropped...confused

[Guest guest]

TSH increases to stimulate thyroglobulin production so that it can bind with iodine to create thyroid hormone. If there is no iodine then there is nothing to bind to so there is no need to stimulated Tg production. Did you test antibodies this time? Your Free's look basically the same. Remember that TSH is a pituitary hormone and not a thyroid hormone.

TSH has dropped...confused

Hi,I would be very appreciative of anyone who could shed some light on my situation...My TSH has always been 1.3-2.3, with a free T4 around 1.2 and a free T3 of 2.6 (260), and negative antibodies. Last year I started iodine, gradually increasing to 50mg/day, for thyroid cysts on ultrasound, menstrual symptoms (long, irregular cycles), and low basal temps (96.5-97.5). My TSH after 4 months of 50mg was 3.3, and free T4/T3 about the same. After 4 months of iodine my cycles were a lot more regular, but I still had low temps.Against my better judgement, a practitioner recommended I stop all iodine, so I did. I have taken no significant amounts of iodine in 8 months. Now my TSH is 0.15, free T4 1.1, free T3 2.98 (298). My TSH has never been less than 1.3, ever.Why has my TSH dropped so much? What does this mean? Thanks for any insight.

I would also add that TSH is needed to produce iodine transport cells. If your

iodine level goes up your TSH will go up to produce more of these cells. If

your iodine level goes down the demand for iodine transporter cells goes down,

thus reducing demand for TSH.

This is explained in Brownstein's Iodine book on page 145.

Yes, I did check antibodies this time, and they were negative again. I just

thought it was weird that it plummeted so much lower, way lower than it's ever

been, even before I knew anything about iodine. Almost like some kind of

rebound effect??

Other reasons I've found connected to low TSH are: low Vitamin A; toxicity

issues - petrochemicals or oestrogen; impact of fluoride on the pituitary.
