Heart disease and atrophied thyroid

[lauriegraham]

Greatly appreciated the response to my previous post, link below, many responses that are helpful that I am digesting. healthunlocked.com/thyroidu...

I saw the nhs endo who is, as seems common for people on here, concerned about t3 use and stated 2 things that i do not believe are right?

The first is that low tsh/t3 use is linked to heart disease and hence t3 is dangerous??

Secondly that using t3 suppresses one's own thyroid so that it will become atrophied and not come back to life if t3 is continued

Any response or counter evidence? apologies if this is well covered elsewhere. I noticed a recent post stating that t3 is now being successfully used for heart failure as well

thanks

He's got that a bit cock-eyed. Low T3 is linked to heart disease. The heart needs a lot of T3. If he believes that T3 is dangerous, why aren't we all dead? Because a healthy thyroid makes T3 all the time. And, if you take just T4, the body will convert it to T3, because T3 is the active thyroid hormone needed by every single cell in your body. How can it be dangerous?

However, he's right that taking T3 - or levo, or NDT - will suppress one's thyroid. Of course it will. Because it reduces the TSH and the thyroid cannot make thyroid hormone without TSH. That's the way it works. However, the thyroid will not atrophy, that's a daft idea. If you had to stop your thyroid hormone replacement, after a while, the thyroid will take up where it left off and start making as much hormone as it can again. I have put this to the test (not intentionally, but due to circumstances) I was on a high dose of T3 only, TSH suppressed, and my thyroid was supposed to have been dead for years (Hashi's). But, I stopped T3 for six months, and my thyroid did wake up and start making as much hormone as it could. When I got tested six months later, my TSH was about 45, I think, but FT4/3 were there, low but just about in-range. And, the only symptom I had was weight-gain. So, he's wrong on that point!

That is si helpful. Thank you. I might need research evidence if there is any around?

Probably, I don't know. But, the article you meantioned about T3 being given to people who've had heart faillure, was posted by diogenes. He posts lots of interesting and helpful articles, so have a look on his profile:

Let's face it, all medicines are dangerous if taken in the wrong way or at the wrong dose. T3 is the same. In my mind, it's laziness when drs say T3 is dangerous - they haven't researched it, and believe all the mumbo jumbo they were once told.
