thyroxine high

[Mostew]

please help a thick woman understand !

For some reason I can never read and digest info on thyroid ….

Had monitor my health test.

tsh 2.46

Thyroxine. 22.2.

ft3. 4.3

Gp. Did TSH. A week later. It’s. 1.16. Had it done at 11.15 but hadn’t had any food . Only water

Feel a bit light headed and more easily irritated.

thanks xx

What time was the Monitor My Health blood draw? The time of day is what is most important for TSH. It's highest before 9 am. So, if both blood draws weren't done at the same time of day, you cannot compare them, whether or not you ate first. At 11.15 the TSH would be nearing its lowest point.

The FT4 is high because you're not converting it to T3, so it's building up. And you can tell that you're not converting well because your FT4 is high but your FT3 is low.

Thanks . That's clear . So do I need more levothroxine? Gp of course says no further action. Might high ft4 explain light headidness ?

[greygoose in reply to Mostew]

It could possibly explain it. Some people do get symptoms from high FT4, but it's not something I've experienced myself. But, it's more likely to be due to the low FT3.

No, you should not take more levo. If anything, you should reduce it slightly, which might improve your conversion a little.

When did you last have your nutrients tested?

Hi Mostew.

What is your current dose and how long have you been on it?

Were your doses the same for both tests you’ve mentioned?

Did you have the tests as per protocol?

TSH fluctuate throughout the day and for various reasons such as underlying infection. So, if at all possible, you need to be guided by both your particular set of symptoms and full thyroid panel inc TSH, FT4 and FT3.

Don't put yourself down....there's a lot to learn about thyroid disease, and you are now starting to do that!!

Can you please add reference ranges to results (numbers in brackets) Different labs calibrate their test machines differently and use different ref ranges

With those we can more clearly analyse your results and answer your question, So do I need more levothroxine?

How much levo are you taking?

[Mostew in reply to DippyDame]

I suppose I feel by now I should have more understanding... but because I'm usually not thinking about what I need to do as felt fine, and results been reasonable I haven't

GPS results on 31st Oct.

TSH1.16. Range. 0.35-4.94

.

Taking. 75mg

Hello Mostew :

Put another way - generally speaking when taking T4 monotherapy once the T4 is in the top quadrant of it's range you would expct to see around a 1/4 ratio between the T3 and T4 :

So with a T4 at 22.00 you would expect a T3 at around 5.50 :

No thyroid hormone replacement works well until the core strength vitamins and minerals of ferritin, folate, B12 and vitamin D are up and maintained at optimal levels and conversion of T4 into T3 can also be down regulated by inflammation, antibodies, any physiological stress ( emotional or physical ) dieting, depression and ageing :

Very helpfull . Thank you I'll. Check when I last had foliate done , but think it was OK

I'm certainly aging!!
