    Hello. I had RAI in 2010 and I’m on Syntgroid.75
    I’ve had an ultrasound and I have no remaining thyroid.
    I have a new PCP who ran my yearly thyroid labs because my endocrinologist retired. She saw my TSH (C ranges below) at 10.4 and wants to increase my Synthroid dose to 100. My FT3 and FT4 are in range. Thoughts?

    FT3…….2.2……range 2.0 to 4.4
    FT4…….1.22…..range .82 to 1.77
    TSH…….10.4…..range .45 to 4.5

    Hi Suz,
    You're on a low dose of Synthroid so a higher dose is a good idea since your FT4 and especially FT3 are low. That will help but you'd probably benefit if you were also prescribed T3 replacement hormone (Cytomel) or switched to a glandular thyroid extract like Armour. I've been on Armour for years after RAI and it really made a difference when I switched.
    Your high TSH shows that your current levels of FT4 and FT3 are too low for your body's needs.
    Best, Elaine
