Re: if a nodule produces thyroid hormone why.....

The TSH is not a thyroid hormone, its a hormone which is produced by the pituitary gland to tell the thyroid to produce either more or less thyroid hormone. If you have too much thyroid hormone in your system the TSH will be low, telling the thyroid to 'slow down'. If you have too little thyroid hormone the TSH will be high telling the thyroid to 'speed up'.
Hope this helps
