I posted 18 days ago regarding my daughter who had lost three stone in weight but had still been taking her usual dose of 150mcg. levo.
She was having really bad sweating at night so we thought she might be on too much levo. now with the weight loss. She reduced to 100mcg. which she took for ten days. I posted here and was advised it was too much of a reduction in one go, so was advised to take 125mcg.
She took 125mcg. for two weeks but was still have bad night sweats so reduced to 100mcg. for two weeks. Still the sweating was bad so stopped all levo. for four days, then restarted on the 100mcg. which she took for two days.
I had ordered a thyroid blood test for my husband, which he never got round to using, and it was due to expire in a few days, as my daughter was feeling really anxious and depressed she decided to use the test.
We obviously knew her thyroid levels would be messed up but she wanted to see what her ferritin was doing as she always has low iron.
So she had restarted her 100mcg. for two days but then did not take it for 36 hours before doing the blood test, also as she is taking biotin and only decided to do the test last minute she did not stop it before the test.
Her results are,
TSH 7.35 range 0.27 - 4.2
FT4 11.9 range 12 - 22
FT3 3.3 range 3.1 - 6.8
Thyroglobulin AB 17.5 range 0 - 115
Peroxidase AB <9 range 0 - 34
Ferritin 29 range 30 - 400
Folate 18.1 range >2.9
Vitamin Active B12 256 range 25.1 - 165
Vitamin D 120 range 50 - 120
CRP HS 2.2 range 0 - 5
She takes all the usual supplements, obviously she can reduced her Vitamin B12 dose as it is well over range.
She cannot take the ferrous fumarate prescribed by her doctor as it makes her vomit, so she takes Boots gentle iron 20 mg twice a day, which is obviously not strong enough as her ferritin is below range.
I know her thyroid levels are not giving a true picture but I just wondered if anyone would like to offer any advice.
oh my goodness! Firstly congratulate her on losing 3 stone, but yes her old dose if the rule follows will be too much.
It usually takes 6 - 8 weeks for a dose to settle down. All the yo-yo-ing will have played havoc with her levels re thyroid hormones.
As you note B12 and folate look high out of range. Might she be over supplementing? Not taking any multivitamins? (Better not to, they tend to be less effective). SlowDragon and SeasideSusie advice re vitamins is legend- helped me tremendously at start of my journey. I’ve tagged them in.
But ferritin is so low! That should prompt a full iron panel.
Taking everything into consideration , no wonder she is not feeling well. The thyroid hormones now being in a state of flux and iron deficient.
What dose is she on now? Whatever it is tell her not to rush to change again- advice when changing dose up or down is low and slow.
What did she weigh before losing 3 stones.
And what does she weigh now. This will be useful to know.
When she was on 150ug of Levothyroxine did she ever experience residual symptoms?
Hi many thanks for your reply.
Yes her B12 is high due to supplementing, she will now stop it.
SeasideSusie has just pointed out, that ferritn levels for women start at 15 (test was sent in in my husbands name) so although ferritin is low, it is now as low as we thought.
I see from your reply to SeasideSusie below, that you seen from my previous post my daughters weight. We worked out she should now be taking approx, 100mcg. levo.
She will stick to this to 100mcg. now and retest in 6 - 8 weeks.
