I wish that I had your numbers. My Reverse T3 is higher than yours, and Free T3 and Free T4 lower, although my TSH is also lower. And I've been struggling with fatigue and anxiety issues for months now that have made me suspect adrenal fatigue, although I am aware that endocrinologists will tell you there is no such condition.
My last 3 months of
thyroid labs (totally off thyroid meds) are:
May 28:
T3, FREE 2.6 NORMAL 2.3-4.2 pg/mL
T4, FREE 1.1 NORMAL 0.8-1.8 ng/dL
TSH 1.23 NORMAL 0.40-4.50 mIU/L
Reverse T3 26 HIGH 8-25ng/dL
THYROGLOBULIN ANTIBODIES <1 NORMAL <=1iu/ml
THYROID PEROXIDASE ANTIBODIES <1 NORMAL <=9iu/ml
DHEA SULFATE 58 NORMAL 38-313 mcg/dL
May 8:
T3, FREE 2.6 NORMAL 2.3-4.2 pg/mL
T4, FREE 1.1 NORMAL 0.8-1.8 ng/dL
TSH 1.09 NORMAL 0.40-4.50 mIU/L
April:
T3, FREE 2.6 NORMAL 2.3-4.2 pg/mL
T4, FREE 1.1 NORMAL 0.8-1.8 ng/dL
TSH 1.50 NORMAL 0.40-4.50 mIU/L
March:
T3, FREE 2.9 NORMAL 2.3-4.2 pg/mL
T4, FREE 1.0 NORMAL 0.8-1.8 ng/dL
TSH 1.17 NORMAL 0.40-4.50 mIU/L
TSH looks good, but Free T-3 and Free T-4 are definitely low. The question is why? With Free T-3 at 2.6, my TSH should be elevated to signal more T-4 to produce more T-3. If it were a T-4 to T-3 conversion issue in the liver, my T-4 should be higher in an attempt to make more T-3, so my body is apparently happy with my T-3 level but it’s not adequate.
It was suggested to me to “consider cortisol. Best way to test it is with a 24hr saliva test, blood test doesn’t offer much insight. With "adrenal fatigue" at first, the thyroid will output more hormone but as lack of cortisol production continues and the body becomes drained, TSH will drop to reduce T-4 and T-3 as the body can't handle the stimulation or energy production. That would explain the low TSH with low T-3 and T-4. This is central hypothyroidism, where the TSH is normal, but the actual thyroid hormones (T-3 and T-4) are low because the communication pathway isn’t working properly.”
I am aware of the theory of T-3 pooling, and the use of small doses of T-3 to help bring down levels of T-3. I know that if I use larger doses of T-3 (12.5-25mcg), it makes me unbearably lethargic and definitely fatigues me more. But if I use nothing, I am often anxious and OCD until I crash and am lethargic and fatigued.
So I wonder whether using small regular doses of T-3 will help?
