3 month Bloodtest

[catpurple7]

Hi all, I had a bloodtest done on Tuesday and these are the results. I'm currently taking 150mcg Levothyroxine, B complex, 1x ferrous fumerate 210mg, vitamin c capsule, 5000iu vitamin d + k2, magnesium capsule daily, I have not missed a day in the last 3 months taking any of the vitamins.

I have put the last test results in brackets. I remember last time the dr wanted to reduce my levo dose but i asked her to keep me on the same dose so i could get my vitamin levels up. Any advice will be greatly appreciated.

TSH 0.01 mU/L 0.30-4.20 (0.01)

T4 22.4 pmol/L 9.0-19.0 (20.3)

T3 5.8 pmol/L 3-5.4 (5.9)

Serum Vitamin D 122 nmol/L 50-250 (93)

Serum Vitamin B12 902ng/L 180-900 (928)

Serum Ferritin 50 microg/L 10-200 (49.9)

Serum Iron 18.2 micromol/L 11-30 (18.1)

Serum Transferrin 2.69g/L 1.8-3.6 (2.64)

Transferrin Saturation Index 27% 16-50 (27)

How do you feel?

Free T4 (fT4) 22.4 pmol/L (9 - 19) 134.0%

Free T3 (fT3) 5.8 pmol/L (3 - 5.4) 116.7%

So you are converting well and both FT4 & FT3 are above range. Thats not where I would want my results to be for myself.

You've been doing really well with your vitamins and all except ferritin look great. Ferritin is notoriously slow to raise and I understand your vegan which won't help. Keep doing what you are doing and time should bring that up.

I still feel very tired and get out of breath a lot. Should I stay on the same dose of levothyroxine?

[Jaydee1507 Administrator in reply to catpurple7]

Being over medicated can cause symptoms very similar to being hypo. In this particular instance it would be a good idea to do what your GP is telling you and reduce your dose.

Low ferritin can cause breathlesness.

Hi catpruple7

I would say you are at the tweaking stage

If you reduce, just a smidgen or you may miss your sweet spot. Better to do it slowly and leave several weeks before checking with a blood test. Then see where you are at, If you need a smidgen less you can tweak , but don't yo-yo not good for you and don't let doctor dose on TSH as it is unreliable - Always your be guided by your thyroid hormones not the pituitary one 😉👍

Should I reduce by 12.5mcg at a time? 🤔

[Charlie-Farley in reply to catpurple7]

Ooooo Just realised I should have qualified that last statement - Everything related back to how you feel. Symptoms are the most important Diagnostic. My lived experience has taught me that!🤗

When was last Levo taken before this test?

Do you have your results on a lower dose?

12.5mcg dose increments either way are a good thing when tweaking.

I'm not the best person to ask but even a 12.5ug per day reduction can have profound effects. I'm tagging a few others in as this is not a strength of mine (I'll be following replies)

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

I would consider reducing levothyroxine by 12.5mcg 3 days a week initially

So 137.5mcg Tuesday, Thursday and Saturday

150mcg the other 4 days

Wait 6-8 weeks and retest

My test was done at 8.30am and my last dose was 24 hours earlier, i had stopped taking b complex and iron 7 days before

SlowDragon’s advice is legend- she came to the rescue with other lovely forum members when I popped my first post up!
