My new doctor said that my latest lab work showed over-suppresed thyroid. I have been treated for hypothyroidism for two years, plus with Armour (natural) thyroid. In the last few months, I've been gaining back a few pounds that I can't shed, having a little hair loss again, increased anxiety, occasional insomnia, and having cold hands and feet - some of the same symptoms I had at the begiining of my treatment. Also, my blood pressure is high again. I haven't received my lab results yet, but am wondering if these health changes truly show OVER suppressed thyroid. My original diagnosis was that my body made thyroid, but was unable to use it properly. Could that still be the problem, perhaps that I am less able to use the thyroid, rather than be over-medicated? Which of the lab results would be definitive for either diagnosis- over- or under- medicated ?
