Advice from you fine people, on increasing my meds please!

I self medicate on NDT and take extra T3 as well.

I am 7wks pregnant.

Free T3 is 3.8 (3.50-6.50)

Free T4 is 6 (10-22)

TSH is 0.12 (0.10-4)

Usually my T3 is in the upper quarter, so as you would expect, the demands of pregnancy show I need to up my T3 a bit. My question is, do you think I need to up my T4 as well? (Pre pregnancy, my T4 was 6, and my TSH was 0.05 so they have come down.)

On another note, I had to see a different doc today to pick up these test results, (which I dreaded as I thought I'd have to give him my "self medicating" life story!) who was really positive and open minded about my self medication and said that I would be the expert in this situation and that he is happy to take his lead from me, and encouraged me to have blood tests every 4 weeks (he asked what "my plan" was, and I suggested the 4weekly tests) and keep them in the loop. He said that in 10yrs he predicted he'd be able to prescribe T3/T4 to most under active thyroid patients......

  • That's nice you had an amenable Endocrinologist and he's interested in T4/T3 combinations.

    When we add T3 into the mix, whether on T4 or NDT, our T4 will be lower.

  • Does that mean that you think I should raise t3 only?

  • I am not medically qualified to advise but, disregarding the TSH, you can choose to increase either NDT or T3. I will give you a couple of links:-

  • Thanks for the links!

  • He was a GP, not an endo!

  • Where can you go for Free T3 and T4 Testing? Pls advise.

  • My GP did mine. (Mine will only test T3 if T4 results are out of range. My T4 is always out of range because I take NDT & it suppresses t4. This one time where their lack of knowledge is a bonus for me!) if yours won't test, get a private test with " Blue Horizon",
