Hi everyone just curious to know what peoples symptoms are when there ft4 is over range but ft3 still in range??..
And also how long before symptoms ease when dose is reduced..
Yes i know some will say i need t3 but i already know this... git to wait on my endo..
Whenever my ft4 goes over range i feel detached spacey weird anxious strange horrible mood drops but feel it in the brain its weird generally not myself...
Anyone??
Do you leave a gap of 24 hours between your last dose of levo and the blood test?
Yes i do...
This is from a past post and copy of greygoose 's response:
You don't say what your TSH is, but if it's high, and your FT4 is high, that suggests that you are not efficiently converting that T4 into T3. And, the answer to that is not to keep the FT4 way over the top of range, but to lower the T4, and add in some T3 - difficult as things stand, I know. But, keep increasing the dose of T4 will bring it's own problems.
So, why are you converting? Do you have Hashi's? Have you had your antibodies tested? Have you had your vit D, folate and ferritin tested? These all need to be optimal for you to convert properly, not just in range. We already know that you have low B12, so the others could be sub-optimal, too.
I think the best person to answer this question is Clutter . She's the only person I've heard say she has symptoms with high FT4.
What I was referring to in the above quote, was T4 converting to rT3 when the level is too high, instead of T3. But, rT3 doesn't cause symptoms, as far as we know.
Personally, I would suspect the symptoms come from low T3, rather than high T4.
my ft3 was at the top of the range when my ft4 went high over range so can only presume its the high ft4 causing symptoms...
but im now debating whether its the actavis brand that doesnt suit me, as had alot of side effects when i started them nearly a year ago, side effects have calmed somewhat but levels still not stable and still feel like im going crazy!!
im currently trying to get hold of mercury pharma to try...
Ahhh... That could well be, yes.
