Hmmm..., not sure if we have a disagreement. I said TSH alone doesn't do much. I said going with how one feels and the presence/absence of symptoms is a key component to any hypothyroid diagnosis. Yet I don't think the Iodine doctors would suggest supplementing indefinitely with Iodine (, selenium, ..) without ever taking thyroid tests (including TSH)... that would be irresponsible, in my opinion.
Now as for my prior post, I sought feedback because my TSH more than doubled (from 5.x to 12.x) ... going from pretty bad to awful. I think it is not inappropriate for me to have been alarmed despite knowing fully well such jumps in TSH values are not unexpected. Such a jump is fine provided I have some idea when it should come back down, which was the main point of my post.
It seems TSH spikes because it is called up to get the sodium-iodide symporter to do its business. This knowledge calmed me down. However I will continue to get my thyroid checked every few months. Even if the results are confusing or momentarily distressing *it is important to know what one's body is doing*. Or at least that is my opinion.
Sorry, but I have joined this forum to help and not argue. So this is the last I will say on this.
