Thyroid-folks, I'm re-surrecting this thread...
So, this summer I came off thyroid meds. The dosage I was on just before coming off, was 50mcg T4 and 45mcg T3. I followed the advice of my thyroid doctor (who I hoped never to have to see again because I was going to be totally fine, right?) and halved the T4 to 25mcg and then reduced T3 by 5mcg every few days. When I was off all the T3, I stopped the T4. All this took about a month.
I then waited 6 weeks and tested. And got these results:
Blue Horizon venous draw (Platinum test)
Off all meds (6wks off)
TSH 2.38
free T3 2.6L (3.1-6.8 )
free T4 12.3 (12-22)
Total T4 64L (66-181)
rT3 17 (10-24)
Reverse T3 ratio 0.15
Thinking I just needed to give it longer, I waited another 4 weeks (so this is 10 weeks off meds) and tested again, this time with Lola Health (who use an NHS lab) and the results were exactly the same:
Lola Health venous draw
Off all meds (10wks off)
TSH 2.66
free T3 2.5L (3.1-6.

free T4 12.4 (12-22)
By this time, my hair was falling out in the shower. My feet were ice blocks at night. I could only sleep about 4 hours again. My metabolism had slowed right down and I was going to end up reducing my food intake and ending up back where I'd started. My skin was really dry. And on the same blood test my cortisol was high and my prolactin was also high. (Apparently both high E and hypothyroidism can cause that.)
Why is my TSH not going high to demand more thyroid hormone?! And why is my rT3 relatively high when all my thyroid hormones are so low?
I re-started 15mcg of T3 in 3x doses a day. And now I'm a bit lost. I was going to take this for 6 weeks - and then re-test and see my private thyroid doctor about it all, with all the results. But someone on FB has freaked me out by telling me it could be central hypothyroidism (ie caused by my pituitary or hypothalamus, not my thyroid) and I should go to my GP and get referred to an endo, and how I might need an MRI and all this scary stuff.
BUT - my GP (I think) is only going to test my TSH and free T4 and these will both look fine (as above). So she's not going to refer me, right?? Or can she still refer me? I can show her these blood results with T3 etc, but they are not NHS results. (Although they are done in an NHS lab.)
Just a reminder... Before ever going on thyroid meds last year, my results were pretty normal:
INUVI venous draw
On no meds
TSH 1.37 (0.270-4.2)
free T3 3.9 (3.1-6.

free T4 18.6 (12-22)
rT3 32 (8-31)
The issue was a low in range T3 and a high rT3. I was given a tiny dose of 15mcg of T3 to see if it helped, due to my severe night time symptoms (which I now think were estrogen related).
It didn't help but it sent my T4 below range (which is normal for T3) - and my old doctor freaked because she didn't realise it is normal for T4 to go below range on T3 only. So she insisted I start 50mcg of T4 and then my TSH got suppressed. I was only on thyroid meds for a year and my TSH was only suppressed for 7 months. Whilst on them, I did a reverse diet, got up to eating 2400 calories a day, high protein - and then, since the thyroid meds didn't help my night time symptoms, I weaned off them.
And now this...
I was thinking - oh no - I guess I just have to be on some amount of thyroid meds forever, then. And that was bad enough and needed some adjusting to. And now this person on FB (who is not in the UK) has freaked me out even more by telling me I need to go get scans and tests and MRIs on my pituitary done. Does anyone know about any of this?
Arrrgggg.. You think you've turned a corner with all this health crap and then there is the next thing.... Will there come a point where I am just living life again?
