OK whats your new T3, T4 and TSH after taking thyronorm 50 mcg for 2 months?
From your previous result it indicates subclinical hypothyroidism which can give mixed symptoms from both hypothyroidism and hyperthyroidism.
So based on symptoms alone its hard to tell. Please post new results along with reference range mentioned in that paper.
What are the reference ranges for the T3 and T4? Reference ranges vary from lab to lab and have to come from your own report. Also, were they Free T3 and Free T4 or were they Total T3 and Total T4? Those aren't the same tests as the Free's and don't give the same information.
Your TSH definitely indicates hypothyroidism, and you T3 and T4 seem to be very low in the ranges, as we normally see them, though we can't know for sure until we see the ranges from your lab report... these, too, would indicate hypo.
While some symptoms of hyperthyroidism and hypothyroidism can be the same, your symptoms of weight loss, sweating, etc may be caused by something else. Have you been tested for diabetes? Those are some of the symptoms my son had prior to his type I diabetes diagnosis. He was, and still is, very thin, but it's nothing to do with his thyroid.
