Re: reverse T3 dominance questions

[Guest guest]

1. what are the normal ranges for rT3?

Depends on lab but most I have seen are roughly 90-350

2. what is a good T3/rT3 ratio range?

The ratio range is over 20 if it is calculated with Free T3 an if the total T3

is used it is over 10.

3. is there such thing as free rT3 and total rT3?

Not that I know of.

4. when fT3 is measured is that only the free unbound T3 or does that

also include rT3.

Free T3 labs DO count RT3 as well as T3, it coults all T3 that is NOT bound to

proteins in the blood.

5. I know that excess rT3 can take up thyroid receptor sites blocking

out T3. I also know that excess estrogen can also take up thyroid

receptor sites blocking out T3 (I would guess that in hyperT it would

be the opposite). What other hormone receptor sites compete with T3?

Estrogen does nto take up T3 receptors, but rather BINDS T3 in the blood where

it can no longer enter the receptors, in other words it si no longer FREE T3.

The more estrogen, the more T3 binding it does. To my knowledge there is ONLY

RT3 that binds to T3 receptors. Receptors CAN become downregulaed (Inactive) if

the bidy is hypothyroid forlong periods of time. Low Ferritin causes the thyroid

to not be taken up by the cells but I am not sure the exact mechanism for this.

Low cortils will down regulate T3 receptors as well. High cortils causes T4 to

T3 conversion to be blocked and favors conversion of T4 ot RT3 causing RT3

dominance.

I'm sure fT3 will be used - but what does over 20 mean. 20 part T3 to

1 part rT3 in the case of fT3/rT3 ratio?

I don't currently take any thyroid meds...I gave up over a year ago.

Is it best to measure rT3 while taking meds or without or does it

really matter?

How long does it take rT3 to clear the system - whats been the range

of time needed for people on this site?

According to Dr. Rind you can easily tell if someone is making excess

rT3 simply by looking at their thyroid blood values before

medication...is that really true?

I took t4 for around 4 years - pure hell. I then took t3 for 1 year -

it was like taking candy, no help. But if it only takes 3 to 12 weeks

to clear rt3 from the system, and I took pure t3 for 1 year does it

sound like I'm on the wrong track?

The T3 - thybon - was German. I took it in divided doses, 4 times per

day. Temps didn't come up at all. And yes, i was taking 7.5 pred at

the same time for me adrenals.

Girl...don't you ever sleep. I writing from Germany where it's almost

noon but by you it's either very early or very late.

I don't know if there is another brand to try but certainly I will

ask. Although since my fT3 blood values were tested at 14.87

(2.0-4.2) while I was taking 140mg of T3 wouldn't that imply it was

potent enough to raise my blood levels for fT3?

[Guest guest]

I totally missed out on hyper symptoms - no shakes or anything except

the kind that comes with hypoglycemia that went away when i ate. Once

I lowered my t3 this stopped.

But wouldn't it be also possible that taking t3 didn't help me (or

hurt me) because too much rt3 was in the system blocking the t3.

~Like i said, my temps never moved or my pulse for that matter.

> YEOEZY!!! Yeah ti wa potent enough but I suspect you sdailed righton

past a good T3 level into hyper land which can feel the SAME as hypo.

It also implies maybe your adrneal support wa not enough to get it

inot the cells. I knwo you have had severe adrenal issues in the past.

I was just reading an article from Dr. Lowe, who doesn't believe that

the body can get 'stuck' in converting into too much rt3. He says

high rt3 conversion rates are caused by fasting, disease or stress

(high cort. levels or cushings) but the conversion returns to normal

within a few weeks of removing the cause - fasting, disease or stress.

Do you agree? What has you own research shown. Do you think the

conversion can get stuck?

Do you know what disease would cause high conversion - he mentions

liver disease but there must be others...like what?

Dr. Lowe also mentions that taking prednisolone can also cause the

high cort levels mentioned in stress as one of the high conversion

causes although he didn't say at what doses.

I'm curious if others have had to stop taking HC or pred in order to

'fix' the conversion problem. I also wonder if I took pred when I was

in the high-cort-phase of AI and if this explains why taking t3 with

pred didn't eliminate rt3 from my system? Or maybe it's disease - do

you think gastritis or ulcers could also cause high conversion?

Any thoughts?

By the way, I don't really agree with Dr. Lowe in that the conversion

problem is always temporary and never 'stuck' although I do agree with

why it gets stuck.

[Guest guest]

Are you saying in the case of some diseases, like hepatitis, a person

would need t3 for life just to compensate for constant high rt3

conversion when 'technically' the thyroid is fine. That the thyroid

problem is only an indirect result of a constant diseased state?

I'm in the process of having a serious gastritis or ulcer 'attach'

(still waiting for test results to confirm dx). Lots of inflammation -

from nipples to navel. Right now it is fairly acute but I think it

has also been chronic for a long time yet I didn't know i had it.

This would also explain why the iron supplements I took which in turn

'improved' my thyroid blood values is actually making me feel worse.

My improved t4 values probably means more rt3 being produced.
