    Weird reaction to Levothyroxine and reverse T3 issues

    I was diagnosed with sub clinical hypothyroidism around 6 months ago, I was very much symptomatic despite only having a TSH of 3ish and low but in range T3 and T4 levels. I was initially put on NDT (NP thyroid but that did little to change any of my symptoms, doctor put me on Levothyroxine...

    Elevated Reverse T3

    Does somebody here managed to deal with elevated Reverse T3 and what was causing it in the first place? FT4 is at the top of the range even can go above if I overdo the selenium, regularly supplementing selenium, zinc, vitamin d etc. FT3 is a bid mediocre(around 2.9-3.3ng/l in range of 2-4.4)...

    How many of you are on thyroid meds?

    And what made you take the leap? Classic low TSH/T4 or T3? I see some of you are having reverse T3 measured which I believe isn't standard practice.

    What is reliable way to measure T3 dose?

    How do I measure what the correct dosage of T3 is right for me? Should I slowly increase my dose until my RT3 goes to normal level? Should it be based on TSH? Should it be based on body temperature and pulse rate (I am aware that my resting pulse shouldn't exceed 80 and body temperature 98.6)...

    High reverse t3 raises shbg?

    I'm always on the higher side of the shbg range, and my reverse t3 is usually high. I'm wondering if its possible that reverse t3 hormones could raise shbg as the active thyroid do? Can anyone confirm/disagree this based on their labs?

    Reverse t3 management worth it?

    Gents, Trt is going well but my last round of bloods showed a TSH of 3.1 with aT3 of 3.4. It was suggested that reverse t3 be run as TSH should be nearer to 1. Reverse t3 has come back as high 32.1 ng/dl (9.2 - 24.1 range). I understand this should be brought back to around 15. Is anyone else...

    Low Ferritin Issues

    I found out that I have high Reverse T3, and subsequent tests revealed that I have very low Ferritin. My first test came in at 34 (30-400), so I began taking an Iron supplement (Proferrin Forte). After 45 days on this supplement, my Ferritin is now at 38. I gave blood once back in June, and I...

    Reverse T3 (rT3): Should it be measured in patients with hypothyroidism?

    There is a lot of controversy about whether reverse T3 (rT3) should be measured to assess hypothyroidism. The normal thyroid gland secretes T4 (an inactive precursor), T3 (the active hormone), and reverse T3, a biologically inactive form of T3 that may block T3 from binding to the thyroid...
