Are those Free T3 and Free T4 or are they Total T3 and Total T4? What reference ranges are given for each of them? Reference ranges vary from lab to lab, so have to be posted with the results from your lab report.
What, if any, symptoms do you have?
I am a female, not a sir... :-)
It appears that you have hypothyroidism... Is TSH the only test that was done? You should also have Free T3 and Free T4 tested, as those are the actual thyroid hormones, whereas TSH is really a pituitary hormone, not a thyroid hormone...
Also, can you please tell us what symptoms you have?
Typically, when one has hypothyroidism, they are given a prescription for levothyroxine. Has your doctor suggested that you need a medication?
There is no particular diet you need to follow... All of do best with a diet that consists of vegetables, lean protein, healthful fats, fruit, nuts, seeds and whole grains in order to get the nutrients our body needs.
