SundayGirl, I find your tone really combative, insulting and rude - not just towards me, but towards others (bombshll) as well, whose views I really respect and value. You're (of course) welcome to participate in this thread, as anyone is, but I won't be engaging with you.
Bombshll, I know what you mean about T3 and not wanting to end up on it long-term if you can help it. I also didn't want to, for the same reasons so i definitely don't find that a 'dubious' thing to say. You are very right that (whilst not impossible) it is extremely difficult to get it on the NHS - and it is really expensive (especially if you need a decent amount of it, I am hoping if I need 15mcg dose long-term, it will be affordable - when I was on 45mcg, I was burning through it). However, I also know that having low T3 (even low in range) has loads of health implications. (Like people with low in range T3 are more likely to have cardiovascular issues, dementia etc). So I definitely want to optimise things with my thyroid and if that means staying on meds then i will. There is also a quality of life thing, because I had a very slow metabolism before - and could hardly eat anything without gaining weight. Being able to actually eat a decent number of calories has been life changing and enabled me to go out to social meals and basically live life again...
I also have a slow resting pulse, it's about 54bpm. Maybe not as slow as yours, but after I had surgery for endometriosis all the alarms kept going off because my pulse was so slow and i had to tell them it was normal for me... At night my pulse is 38bpm in my sleep. On this 15mcg T3 it has raised to 42bpm, which is probably a good thing.
kathleen, the most important number to look at is your T3. Not your TSH or free T4. You do want to know those as well but it's like trying to understand what's going on without the full picture. For eg, at the moment my TSH is normal and my free T4 is in range (just) - but my T3 is way below range and I feel awful. If I didn't know my free T3, I wouldn't have the info I need. Unfortunately the NHS doesn't test T3 in most thyroid patients via GP so you have to do this test privately. But also how you feel is very important too. Just as with HRT it's a very individual thing and one person will feel fine with numbers that would make someone else feel really bad.
cs24, my understanding of what's happened (for me) isn't quite the same as what you say there. I am definitely a poor absorber and I am lucky to be with Newson and be able to get access to high doses. However, increasing the estrogen has helped me so much. I had turned a huge corner a couple of months ago, by increasing it. Then I weaned off thyroid meds and I think basically the symptoms of low estrogen and low thyroid are very similar. So now I am working on the belief that my estrogen is in a good place but my thyroid levels need to get back where they were. I have explored histamine intolerance about 2 years ago, with a low histamine diet - it didn't help. And I don't believe in 'estrogen dominance' - there is no such thing, it is progesterone deficiency(!).
Don't forget that our bodies have estrogen up to 20,000pmol during pregnancy and around 1000-1200pmol during ovulation. Instead of focussing on the dose someone gives you, look at the serum estradiol levels. Many women need to be between 450-650pmol to be symptom-free during peri due to the fluctuations. At 890pmol, I was too high - unless I really needed to be there. I have heard of some women who need to maintain around 1000pmol to be without symptoms. I first tried cutting out the gel completely which should have taken me to around 550pmol (this is all worked out by dozens of blood tests during my period over 2 years on various dosages) - but this was too low and I got my symptoms back. So I halved the gel to 3 pumps at night and that seems to have done the trick, I reckon I should be around 650pmol now but will test again in 6wks and see. I still need to sort out the thyroid... but I don't think I can rush that if I want my own thyroid to recover.
I think there is a lot which isn't understood about the ovary-brain connection yet. When the ovaries fail, this communication also gets messed up - and the brain can react to this causing a lot of neurological symptoms. It's incredible all this hasn't been researched yet.
