Hi - I've found this forum very helpful and have learnt a lot. I've worked up to a dose of 175mcg of thyroxine over the past 18 months. I've just had a load of blood tests and there are a few things that are concerning. The main issue is my ferritin has dropped from 20 (on my last test about 4 months ago) to 17 most recently, despite supplementing twice daily with vit c high elemental liquid iron on prescription. I've never had ferritin levels over 20 in 5 years of testing.
Also, the GP wants to put down my dose of thyroxine as I've gone from a TSH of 1.21 a few months ago to 0.02 most recently. However, this is the first dose that has halted some of my symptoms including hair loss, aching eyes and join pain. I'm still feeling knackered though although this is probably down to low ferritin.
My blood test results are:
TSH 0.02 (0.35 - 5) was 1.21 on 150mcg of thyroxine
Free T4 18.6 (9 - 21) was 20.6 on last test
Ferritin 17 (15 - 200) was 20 on last test
Folate 16.3 (3.1 - 20) I've been supplementing for last few months and it's gone up well
B12 621 (200 - 900) also been supplementing and it's gone up from around 400
Does anyone know why i can't maintain ferritin levels and that they are dropping despite supplementation? Also is my TSH too suppressed now? My haemoglobin is 14.1
