another thyroid resistance question - confused!!

[Guest guest]

Hi All.

[i read the very informative thyroid resistance thread and started this one so

as not to hijack. If it is appropriate/preferred to post a question about me

(rather than giving help to someone else) on the other thread since it's about

thyroid resistance, let me know. Just really want to respect the process and

not obscure someone else's question.]

Val, you replied to someone:

<<<<Yes taking thyroi meds WILL supress TSH BUT your levels even WITH the meds

are NOT high enough to supress it to this point. When you get FT3 to 420 I woudl

expect to see TSH where it is now. Thsi si telling me either your pit is not

functioning correctly ( unlikely) or your body is nto able to tolerate thee

thyroid (VERY likely) Usually this si from lwo cortisol or low ferritin.>>>>

So, I'm not sure what my TSH was telling me. But, I think this is super

IMPORTANT to make sure I understand so I can best help myself.

I am now on T3 only (for four days) and before that I switched from 1 grain of

armour to 2 grains of NT for a couple of months, or so. On the 1 grain of

armour my RT3/T3 ratio was 17. When I upped to 2 grains it was 11.8, and I felt

much worse - my brain felt like it couldn't work - brain fog, confusion, etc.

much worse. That lab also showed my TSH was low on the latest test (which it

wasn't on the lab when I was on the 1 grain of armour), which I ignored because

I thought it was just that I was on more meds and that was to be expected. So,

I want to post the labs I did two weeks ago while on the 2 grains of NT again to

be sure it isn't showing that the CAUSE is still an issue, or if just switching

to T3 only will be enough:

RT3: 28 (range: 11-32)

FT3: 331 (range: 230- 420) this is the HIGHEST my FT3 has been in years

(RT3/T3 ratio: 11.8)

FT4: 1.1 (range: 0.8 - 1.8) it was 0.8 in the lab before

TSH: .06 (range: .40-4.50)

- doc wanted to check my pituitary, as well:

ACTH (serum): 18 (5 - 27)

Vasopressin: 1.6 (range: 1.0 - 13.3)

Prolactin: 10.7 (range: 3 - 30)

FSH 110 (range: 1 - 9)

my pituitary is jamming out FSH and LH and not producing enough vasopressin

(There are more sex hormone labs. My LH is way high, estrogen was low, but high

in the test before that and in between in next test! Testosterone tends to be

high/normal, progesterone low, and I'm supping. DHEA low, so supping with 15mg.

Also on .125mg fludro because of low aldosterone and horrific low BP sxs.)

I have a long hx of having low T3. I have a hx of HIGH cortisol, that can dip

low, but is more high, though I've been treating that. Also, LOW ferritin - 6 -

though after 5 rounds of IV iron, it got up to 150, I think it was!! That was

in June, I think. I am going to do a ferritin test again today or tomorrow to

see if it stuck.

SO, DO MY LABS SHOW THE CAUSE IS STILL AN ISSUE?? (Can HIGH cortisol cause

thyroid resistance, or is it just low?)

Thanks guys,

Carol
