Low B-12 without anemia?

Hi, I am a newbie here.

I've been (unknowingly) having symptoms of low B-12 for over two years now. I've experienced rapid involuntary eye movements, neuropathy in my hands and feet, fasciculations all over my body, headaches, joint pain, memory loss, and facial twitching. I had a CBC in January but it was normal, so can one have low B-12 without anemia or should I be looking into other ailments?

  • Hi

    And welcome to the forum,you mention you have had a complete blood count,could you post your results on the forum so others can support you in identifying your symptoms and condition.

  • Your symptoms could be down to B12 (and no, you don't necessarily have to have anaemia if you are deficient). But they also could be due to many other causes.

    Have you been seen by a neurologist?

  • I've never been to neurologist but my PCP told me the neuropathy and twitching were both due to a pinched nerve.

  • 25-30% of people who are B12 deficient present without anaemia.

    The anaemia associated with B12 deficiency is macrocytic - larger rounder red blood cells than normal.

    There is a huge overlap between the symptoms of B12 deficiency and a number of other conditions including thyroid, diabetes, lupus etc etc.

    Have you had serum b12 and folate measured at all - and if so do you know what the results were?

  • Hi, I posted my CBC below, do you think you could help me understand the results? I've never had my B-12 or folate levels measured btw.

  • Here are my CBC results. I never bothered to look at them until now since the doctor told me everything was normal. I am low in Red blood cells, hemoglobin, and Hematocrit. Are those levels low enough to be anemic?

  • Difficult to really read the tests without the normal ranges (which would be in brackets normally) but the main ones I'd be looking at in relation to B12 deviciency are

    MCV (high in macrocytic anaemia and low in iron based anaemia and think yours is towards the bottom)

    Red blood cell distrubituion width - which seems towards the high end but think is probably still in range (just)

    Don't have problems with iron so not really that up on reading the iron and certainly don't remember rangest that well but think you haemaglobin looks a bit on the low side but still in range.

    so, really looks petty inconclusive. Suggest that you discuss further with GP - ask about serum B12, folate and ferritin (which is another marker for iron problems) and please discuss iron supplementation with your GP - or pharmacist if you can't get sense out of GP - before supplemetning for yourself.
