Advice on latest Results please

[Sami-M]

I’ve been on 137.5mcg Levothyroxine since December 2019 to date. I’m puzzled why the current results are less than optimal and fluctuating since December 2019 as I’ve been on the same dosage of 137.5mcg since December 2019.

Current symptoms, generally good, but lethargy sets in late afternoon; insomnia as always.

Results 12th MARCH 2020

FT3 5.39 (3.5 - 6.5)

FT4 17.74 (11.5 - 22.7)

TSH 0.012 (0.27 - 4.20)

So that’s through the range:

FT3: 63.00 %

FT4: 55.71 %

Levels do tend to jump around with Hashi's, as the thyroid is slowly destroyed, sometimes causing the dying cells to dump their store of hormone into the blood.

Thank you greygoose.

Then imperative for 6 weekly tests and ensuring a within range low TSH and FT3 FT4 in 60%-70% range ? Hence a dose increase warranted by say 12.5 mcg to 150 mcg to help me get back there ?

[greygoose in reply to Sami-M]

I don't think you should be aiming for any precise numbers. You want your levels to be wherever they make you feel well. That could be a lot higher than 60-70%. Blood tests are at best a vague guide. It's how you feel that is most important.

[Sami-M in reply to greygoose]

Understood, thank you. Comparatively I think I felt better back in December but it was all new unchartered territory, although I found it emotionally taxing at the time. But looking back over 2-3 months I feel the lethargy kicking back in slowly.

[greygoose in reply to Sami-M]

Well, that's not surprising, given that your levels have gone down. Perhaps it's time for an increase in dose?

[Sami-M in reply to greygoose]

Yes I’m thinking just a small 12.5 mcg nudge upto 150mcg.

Thanking you !! 😁 xx

Try it and see. You can always increase further at a later date if needed.
