Re: Is caffeine bad for Hypothyroidism or is it stimulating the thyroid?I'm confused

[Guest guest]

hi Roseanne

I really don't think you have to worry about caffeine if you are properly

treated. I love my real coffee with cream in the morning.

Somebody tells me!I'm really confused as caffeine is a strong stimulant

for every vital function.Thanks.Roseanne

Caffeine, in many people is a positive thing. However, for some people it can be

a

problem, like me, who has atrial fibrillation, and the caffeine could kick off

an attack.

Everyone is different. Just learn all you can and apply the information to you

in

particular. You may not have a problem with cafffeine, and so you won't have

to

worry.

Caffeine exerts its general effects by activating cyclic-amp. It

therefore acts like adrenaline, effectively a synthetic form of stress,

which increases cortisone and other adrenal steroids and serum glucose.

It can offset or mask some of the milder effects of hypoT or lack of

sleep. However, any form of " stress " is not a good long term solution to

metabolism problems. It does not significantly stimulate thyroxine

production. If anything, it does the opposite by increasing RT3.

Within limits, usually set by the effects of too much caffeine, it has

not proven particularly harmful in otherwise healthy people. It does

aggravate other conditions, such as diabetes, though.

As I said, the mechanism is that caffeine, like ephedrine (Ma Huang)

mimics adrenaline in inducing hypercortisolemia, which is widely

documented to increase RT3. Just do a search on hypercortisolemia and

you'll find hundreds of studies that all start by restricting caffeine.

In fact, the effect of hypercortisolemia on RT3 is the essence of

's (hypothetical) RT3 Dominance syndrome. Here is one source that

mentions both effects together, _Endocrinology of Critical Disease_, by

K. Ober, Ed., Humana Press, 1997, ISBN:0896034224, p. 256.
