I have recent blood tests but am unsure what they mean. My TSH is 1.847 - my T4 is 1.16 - and the Triiodothyronine, Free, Serum is 2.6. The last seems to be the only one on the low side. I am experiencing fatigue, weight gain, lack of sleep, and mood swings among other things. Do you feel a low dose of thyroid medication is warrented and might be helpful, what are the risks if I do not need this medicine? I am 48, beginning menapose and have Fibromyalgia. Thank you for your time.
