Temperature effects of Thyroid Hormones- New Swedish data

[tegz]

Interesting early look at what could make thyroiders hot [or cold].

Note: This is a study on mice with mutated hormone receptors!

Quote-[Researcher] Dr Warner added:

"We'd also like to see the use of infrared thermography extended to humans, to see if any heat dissipation differences can be seen between euthyroid and different thyroid conditions."

Sounds like a idea whose time has definitely come for Dr.B. Barnes supporters

A good overview of his work and some tips on temp monitoring inc.drbobnd.com/low_thyroid.htm

Be aware though: Most Drs in UK do not understand the effect of low metabolism on body temperature on Thyroid patients. But it is a good test to run. I did and my results were ignored!

It was mentioned here a couple of weeks ago:

I mention that mainly because of the comments/links on that thread.

Thanks ,Rod I missed it then, being away.

I was hunting for the E.Coli LH DNA link when I came across it. [NO luck]

Won't hurt to repeat- a lot of that on here, anyway

I was also interested in the possible effect on High BP- which I have [treated].

[helvella in reply to tegz]

Absolutely! We all miss lots - especially now that posting levels have risen somewhat.

HI guys. That's dead interesting. My hands and feet tended to be cold when I was hypo - I was always being told to keep my hands to myself by the better half. Everything nice and warm now since sorting out a properly functioning T3 based replacement regime.

I find it a bit scary that the work hasn't it appears been done to establish something so basic as whether or not the effect actually changes our temperature though...

I guess Tegz that you've figured that vasoconstriction might also have a role to play in the blood pressure effects of hypothyroidism - but guessing it could be too that there are other mechanisms involved so that when dilation is required for say cooling that it doesn't necessarily lead to an inappropraite reduction in blood pressure.

Don't suppose that you found anything?

Not looked deeper Ian. I had a headache

One main point though - vasoconstriction will lead to increased BP due to pressure in the 'pipes' going up with the same retained volume.

Feedback mechanisms in the ACTH system, kidneys, fluid retention etc all come into play. When these go wrong- then trouble ensues.often a target of BP meds- notopriously ineffective.

HypoT is said to lead to low BP, but I'm NOT a case in point- temp @35+ for ages and BP very prone to diving up, once being 240/120 under the care of an Endo...Been reported here a few times that BP can go either way for Hyper/Hypo.

I suppose it depends on which of the multiple static and transient mechanisms come out on top!

Similar to myself in some ways as you probably know Tegz. My temperature was down when I was hypo, but my blood pressure started to rise as the hypo became more marked back in the early 90s - and with related (?) tinnitus has been a problem ever since. Cortisol and/or other adrenal hormones seem as you also know to be a big part of my situation - with gut related auto immune (foods etc) and mental but less so physical stress acting as triggers.

Beta blockers are the only medication that really drops it. That's at the price of fatigue, and a pretty short lived effect - i'm not much of a fan of BP meds either.

I've had several hospital work ups under consultant physicians, endos and the like too with very high blood pressure numbers like what you list - but none ever added much or investigatedd root causes beyond having a fiddle with the mix of blood pressure meds. Always happy to claim the credit when it naturally subsided after a few days relaxation in hospital though.

The trigger is typically periods of more acute stress (on top of pretty much a life long hassle), with an underyling weakness in ability to cope with it - it was typically birth family related and most recently to do with care of elderly parents. That scene is pretty much past now and the focus is on healing.

I'm as you know inclined to suspect that abnormal stress responses are the big factor in my case, and have been investigating re-programming possibilities. I'm actually about to post a link to a web page i've just found run by a well known endurance training coach - it seems that the whole business of dysfunctional stress responses caused by disturbances to/inappropriate re-programming the HPA axis in turn caused by over training (and i wouldn't be surprised use of chemical assistance) has become a significant issue in the heavy duty training brigade...

Yes Ian, the cause of Wilsons' Temperature Syndrome is reputed to be learned response 'stuck on' ON in the HP Axis. It's NOT the same as Hypothyroid, but it may co-exist, not sure of the etiology there.

Low dose [I think 7 ug] T3 3td for a few days- repeated till success, seems to be the treatment.

The breaks are presumably to stop the stuck HPA 'locking on' to a new friend [in maybe dodgy clothes]

My BP responds to low stress lifestyle and low dose multiple meds. 1/2 normal doses- little is more!
