Hello All,
Apologies for the long post
I have found such helpful advice on this forum - eternal gratitude to the admins. I have not posted much but have certainly learned a lot.
I'm writing today for advice on T3 and for any thoughts on the interaction between my HRT and my levothyroxine
I have autoimmune thyroiditis (Ord's I suppose or more commonly called Hashi's)
My thyroid was removed in 1994 and I've been on Levothyroxine 100 mcg ever since. I function but don't have much stamina and have lots of hypo symptoms (dry skin, brain fog, dry eyes, fatigue, etc)
I was told many years ago that I am a poor converter from T4 to T3 and that I should ideally be on Armour. But I was living abroad where it wasn't available and so sadly that wasn't an option. I moved to the UK three months ago and am keen to find a way to feel better.
I am also on bioidentical HRT (Estradot patches, 100 increased to 137 twice weekly and 200mg progesterone daily).
My gynecologist increased my estrogen patch dose to from 100 to 137 two months ago. My levothyroxine dose stayed the same. I began to have MASSIVE hair loss. Hair loss is always a key hypo symptom for me. I suspected I needed to increase the levothyroxine due to the increased estrogen dose. I understand that estrogen can block thyroid hormone uptake.
I increased my Levothryoxine dose to 112
My GP practise ran routine blood tests two weeks ago - I didn't realise they would run a routine TSH so I wasn't fasting. It was noon.
That TSH result was : TSH = 2.06 mU/L (0.3-4.2)
Of course the GP did not run tests for T3 or T4
When I saw that TSH result, I thought this was the reason for the hair loss and increased my Levothyroxine to 150 mcg every other day, alternating with 112 mcg. (I have supplies at home that I bought abroad)
The same week as the GP blood draw, I also booked a Medichecks test, results below (done at 9:00 am on an empty stomach, as I have learned thanks to this site !)
TSH 1.41 mIU/L (Range: 0.27 - 4.2) (
Free T3 4.1 pmol/L (Range: 3.1 - 6.8)
Free Thyroxine 18.7 pmol/l (Range: 12 - 22)
Thyroglobulin Antibodies 61.1 IU/mL (Range: 0 - 115)
Thyroid Peroxidase Antibodies X 45.2 IU/mL (Range: 0 – 3)
(I see that the T4 to T3 conversion is really low)
CRP HS = 2.1 mg/l (Range: 0 - 5)
Ferritin = 108 ug/L (Range: 13 - 150)
Folate - Serum = 8.1 ug/L (Range: > 2.9)
Vitamin B12 - Active X = 181 pmol/L (Range: 25.1 - 165) (I was supplementing, will stop)
Vitamin D 83 = nmol/L (Range: 50 - 200 nmol/ ( I guess this can be higher)
Looking over these results, I see that
1) I am poor converter from T4 to T3
2) My vitamin D could be a bit higher
3) B12 is a bit high so I will stop supplementing
4) My HRT and levo dosing is not optimal (as in my HRT is affecting my levo uptake)
My problem is I have such brain fog I am struggling to figure out what direction to go in. Reduce HRT patch? Stay on 150 mcg levo every other day?
Ideally I would like to trial T3.
Your thoughts welcome!
Many thanks
