I have been taking .137 L-thyroxine for years. Recently, I was tested and my T4 is 1.6, and was .06.
They have changed my medication from .137, .125, .112 and now are trying .100. My TSH is now at .03.
What should my TSH be, and why are they lowering my medication? Can weight or menopause cause changes?
Menopause was several years ago though, and meds were not changed then. I have lost 15 lbs. but am overweight.
