B12 deficiency
Posted , 6 users are following.
I am a 35 year old female, and about a year and a half ago I had iron-deficient anaemia. I was treated with iron supplements and my iron levels are now ok. However, I have felt utterly exhausted over the past few months (no matter how much I sleep) and have been suffering with poor memory, confusion, lack of concentration, regular ‘brain fogs’, headaches, dizziness, palpitations, shortness of breath and general feeling of nausea. I assumed the anaemia returned (or I was just loosing my mind!) so asked my GP for a blood test.
The results came back, and my iron levels were fine, but my B12 levels were low:
Transferrin saturation index 24% (range 16-50%)
Serum iron level 16.5 (range 11-30)
Serum ferritin: 19 (range 10-200)
Haemaglobin estimate: 125 (range 120-150)
B12: 127 (range 180-900)
I read the information on the NHS website and patient.info and felt an enormous relief that there seemed to be an explanation for how I was feeling, as my symptoms seemed to match those of B12 deficiency. I also read many case studies where levels of around 127 were considered very low, and patients experienced similar symptoms to me.
I saw my GP last week to discuss my test results. I was told that they were all normal. When I questioned the B12 result, she said my B12 levels were slightly low, but that “we are all a bit deficient in some vitamin or other”. When I asked if it could be the low B12 that was causing my symptoms, I was told no, and that I probably had post viral fatigue syndrome. When I said “But I haven’t been ill!” I was then told that I must be depressed (I'm not). She said there wasn’t any point in further testing for pernicious anaemia, because my blood test shows I’m not anaemic.
The GP recommended I take multivitamins (which I already do, and have done for years). I was fairly desperate, so asked her outright if I could have B12 injections and she reluctantly agreed.
Does anyone have any advice? Specifically:
- Should I see a different GP to discuss this problem? 127 seems lower than it should, so surely this could be causing these symptoms?
- The GP agreed to the 6 loading doses, but should I ask for more? The NICE guidance suggests that where neurological symptoms are present, you should continue with the injections every other day until symptoms stop improving, with possible referral to haematologist or neurologist . Do the confusion, brain fogs, memory loss and headaches count as neurological symptoms? I don't want to risk any permanent damage.
- Why would my B12 levels be low? Is this pernicious anaemia (even though I'm not apparently anaemic)? I do have psoriasis which is another auto-immune condition, but am otherwise healthy, eat a good balanced diet, with plenty of meat so why wouldn't I be absorbing B12?
Thanks.

I would take the supplement shots she is willing to give..wait a couple weeks and have it tested again.....and if it is NEEDED again...than get a second opinion from her as to why it keeps happening and if you are not happy with her answer....
Go somewhere else for another opinion. For now, its very possible the shots will help you and then after the shots...end all 6.....the week after...start taking a B12 with your Multivitamin everyday. maybe.
