Tsh low -- what does it mean?

[Hopeful]

Andi,

"Sub-clinical" refers to the fact that while my T3 and T4 are normal, my TSH levels are not, and, the direction they are heading, I would be fully hypothyroid if they hit a value of 10, regardless of where the T3 and T4 values are (mine have hovered between 6 and 7 since I first had them tested in 2004). I have other symptoms consistent with hyopthyroidism, mainly some early bradycardia, which, in turn, causes hypertension. In short, I am a mess! There is controversy in the medical community about when to treat sc hypo/hyper thyroidism. A good endocrinologist is essential.

The link between thyroid and bc is iodine - the thyroid is the organ that uses the most iodine in the body, followed by the breast. R.B. has a thread on this in the nutrition forum, if anyone wants to take a look there.

Hopeful
