Under active to Overactive?

Hi all!

Diagnosed with hypo late 2021 (TSH 8.4). They put me on 25mg Levo and bloods came back good two months later (3.1 - see second photo). After this, my TSH started rising again and I made my way up to 100mg of Levo - started November 2022. Now, my TSH is low???? Am going to see a doc, but in the meantime, can anyone make sense of this?

TSH is frequently low when adequately treated

Your high thyroid antibodies confirms autoimmune thyroid disease (hashimoto’s)

You need TSH, Ft4 and Ft3 together

Always test early morning and last dose levothyroxine 24 hours before test

ESSENTIAL to test vitamin D, folate, B12 and ferritin

Have you had these tested

What vitamin supplements are you currently taking

To accurately evaluate thyroid function we need to focus on the thyroid hormone labs for FT4 and FT3 rather than onTSH which science proves is not an accurate marker

This link should give you more info before you see your medic!

Normally as hormone levels rise TSH falls so nothing strange there....that's how the body works. At 3.1 it is still on the high side but Hashi's may be causing hormone fluctuations can raise TSH.

The important question is, "how do you feel?"

If symtom free then your dose is likely to be correct , if symptoms still remain then adding another 25mcg levo should help.....you have plenty room to add this. This should also reduce TSH which when medicated should sit close to 1

It's not always this clear cut but in your case it possibly is!

Follow SlowDragon's advice re essential nutrients....they support thyroid function

Good luck!

looking at your test results dated 22 Feb 23 and that you say you are now on 100mcg levo up from 25mcg initially I think you are on slightly too much levothyroxine. Best TSH place to be is around 1.00 in my experience. Which means keeping your T4 and T3 levels at a sweet spot for you. You could try dropping your levothyroxine dose very slightly. Maybe do 75 one day and 100 the next for a few weeks and retest. I take Liquid Levothyroxine which means I can tailor my dose very easily. With tablets it’s a bit more tricky. I’m prescribed a dose of 75mcg a day which tips my TSH into suppression. I decided to drop my dose by 10% to 68mcg a day and hey presto my TSH is now in range.. just. Most importantly i feel much better when my TSH is not suppressed. I also take T3 medication liothyronine as I’m a poor converter. Looking at your T3 results you seem fine converting presently. It’s all a balancing act really and finding your sweet spot. Also check your vitamins B12, ferritin, folate and vit D. They all need to be optimal. A lot of hypothyroid patients have low vitamins. If one or more are low try supplementing or eating foods which contain higher concentrations of the vitamin. Vit D though is mainly found by exposing your skin to the sun. If you don’t take your medication the morning of the blood draw remember yourT4 results would be different and higher if you did. The TSH showing suppression indicates you are over medicated. I have done test with and without ingestion of medication.
