Hi folks... a query regarding absorption issues.
Would I be right in thinking that I could not possibly have absorption issues - pernicious anaemia (considering the gluten intolerance I have and the Hashimoto's and the UCTD), because my serum vitamin D rose from 41nmol/L to 101 nmol/L last autumn (after taking 4000iu sublingual spray)... does it prove this? Let me explain:
My rheumatologist agreed that my vit B12 was low and requested my GP give me injections (my b12 was 284 ref range 223 - 1100)...GP listened and said that in the light of being hypothyroid and the gluten issue means that I may need to be over 500. She agreed to the injections but I didn't have them as I took ill with high BP in April and have been unwell since.
Here in lies the paradox - the endo I was refered to a couple of weeks ago jumped at me when I told him I was low in B12 - he asked me 'who told you that?' Instead he has decided to retest for it and told me not to have injections until I see him again on the 28th August (having a scan on thyroid before this too).
Looking at what he has tested he has NOT asked for TPOab / TGab but Thyroid receptor (thought this was for Graves?) ... a little confused.....Neither has he tested antibodies for PA.
What would another low b12 show him other than it being just low without the antibody test?
Can I assume if I take a sublingual spray as I did the vit D, and my serum b12 rose, then I don't truly have absorption issues?
So sorry about the long winded post but I need to be well informed before I see my GP tomorrow to discuss all this.
