first let me say that I have an enlarged thyroid, but all of my tests come back that I have a happy and healthy thyroid, and this has been going on since 2004. So, the only conclusion I can come up with is that I am iodine deficient. So, iodine deficiency is not just hypothyroidism. I only have a goiter, and heart palpitations from time to time.
And secondly, iodine is not as common in our foods as it used to be.
