I got my blood test results today and my my FT3 is 7.2 (FT3 2.60 - 5.70) I take 60mcg of Liothyronine (20-20-20)daily , looking back on my posts this has happened every 2 years or so. My GP wanted me told me to reduce my dose my 20mcg daily but I told him I did a 20mcg reduction 6 years ago and it was too big a drop , so we agreed on 50mcg daily and a blood test in 6 weeks. I took my T3 20mcg dose 12 hours before my last test. Does anyone on T3 only experience this seasonal change?
Thanks in advance

I didn’t experience a seasonal change when on T3 only myself but can I ask how you arrived at splitting your dose into 3? If you can slowly work up to taking it all in one go daily in the morning, then when you have your next blood test you will have left 24 hrs between your last T3 dose and your blood test instead of 12 hrs so your fT3 will be lower. On the other hand this dosing regime may not work for you but could be worth a go if you don’t want to reduce.x
T3 should only be dropped - or raised - by 5 mcg at a time.
Do you have Hashi's? Because if it happens about every two years, that's not a seasonal change. Seasonal would be every 3 to 6 months. So, there must be some other explanation, and the most obvious is Hashi's.
You'd be amazed at the number of times patients have not been told they have Hashi's because doctors don't understand why it's important. I wasn't told by the endo that diagnosed me, and I didn't know what antibodies were. So, I didn't find out I had Hashi's until years later. Never over-estimate an endo or a GP!
I asked for my blood test results and got this reply. I have asked for a copy and T3 level.
Hi Francis, your TSH was 0.04, T4 was <1.3, and your thyroid peroxidase antibody level was raised - this is linked with auto-immune thyroid problems, which is the most common cause of hypothyroidism. I will send you a link to arrange a call with one of us to discuss these properly.
Hi , so ( assuming these are new results from taking lower dose of 50mcg for 6 wks ish )
the low fT4 is to be expected cos you're not taking any T4.. and the fT3 is now within range .... the TSH is pretty low , but not low enough to cause concern in someone who is taking large dose of T3.
So hopefully GP will be happy enough with new results... but more importantly .. how do you feel on lower dose ? .... no point in having nice looking results if it makes you feel half dead.
adding these in case they come in useful when discussing things with your GP , here's a list of references showing TSH of 0.04 or above actually has no more risk than a TSH 'in range' does for patients taking thyroid hormone replacement : healthunlocked.com/thyroidu...useful-evidence-that-tsh-between-0.04-0.4-has-no-increased-risk-to-patients-on-levothyroxine-updated-new-study-does-show-small-risk
And one with links showing why TSH is a bit lower in patients taking thyroid hormone , and why T3 lowers it relatively more than T4 does : healthunlocked.com/thyroidu.... tsh-is-just-the-opinion-of-your-pituitary-about-your-dose-but-your-pituitarys-opinion-is-a-bit-warped-once-you-take-thyroid-hormone.
glad you're feeling better Frank , regarding the eye things ... happens to me too occasionally , often when i'm changing dose, or when dose isn't quite right, or maybe it's just coincidental/ not related at all , i've never been very sure to be honest. ... but be aware that if they continue it's probably something you should mention to an optician.
ok so fT3 level looks good now. ( something went wrong with adding the images , they won't enlarge , but don't worry we can see it well enough .... i have no idea what is wrong cos i'm a luddite )
GP may still want to discuss reducing T3 dose further due to low TSH , but don't let them if you feel ok where you are. There' nothing concerning about a TSH of 0.04 in someone taking T3 who feels well and fT3 is in range.
