Hello all,
I'm new to this group, I have autoimmune thyroid disease, but along with it have been looking at sorting out my iron and B12, so would like to share this here, apologies for the long post... I'm new to dealing with PA, please be gentle
Recently I've been feeling pretty crap - the usual stuff, fatigue, knackered all the time, low mood, no interest in things, hair falling out, but also with a few worsening symptoms - including cognitive decline, and by that I mean like short memory, feeling spaced out, can't concentrate at all and the thing that is getting to me is that it's starting to noticeably affect my work.
I'm positive for Hashimoto’s and I had a routine thyroid and blood panel the other day, and while they only did TSH (standard) my bloods came back a bit odd and now I'm more confused than ever.
(Note I followed all the usual thyroid testi G advice - the test was at 8am, 24hrs before my 100mg levo, no biotin 2 weeks before). TSH came out at 0.86 mu/L (0.2 - 4.0) - although that is not what I'm discussing in this post, just fyi.
Context: I've been supplementing iron since 2021 having been borderline anaemic with really low serum ferritin levels in 2021 ie. 17 ug/L, then 24, then 32 all (10.0 - 291.0) so after so much hard work, it slowly crept up. I'm also an avid meat eater with a varied diet.
The test I had yesterday didn't include serum ferritin owing to a shortage of reagent? (whatever), but other parts of my haematics tests came back as abnormal:
Transferrin saturation Index 52% (<40.0) Outside reference range / abnormal
Transferrin level 2.3 g/L (2.5 - 3.8) Outside reference range / abnormal
To me, both of the above suggests my iron now looks too high (which would have been laughable 2 years ago) but the results have prompted them to give me a phone consultation (date tbc)...
In addition to this they also tested a few other things including my Red Blood Cell count which came back as pretty low: 3.85 (10*12L (3.8 - 5.0).
So, on the one hand it looks like I have iron saturation, and on the other hand possible anaemia / vitamin B12 or B9 deficiency anaemia??
I checked back over my previous labs, and I've consistently had a low red blood cell count - around the same results 3.8 (10*12L (3.8 - 5.0) each time for about 1.5yrs. The same can be said for my Mean Cell Haemoglobin level. My last B12 test was a year ago and was 480ng/L (211-911), and 510 before that, then 422 back in 2021(same ranges).
Do others agree that it is probably B12 that is the issue? the symptoms do match up - cognitive decline especially. Or could there be obvious other things going on here that I've missed?
NB. I'll ask my GP for a B12 test when they eventually get in touch, will see how that goes. But in the meantime I'm a bit worries about taking B12 supplements in case they somehow impact / increase my iron further - is that a possibility at all?
Thanks everyone,
Eb
