I am new to this board, but had a couple questions regarding my recent blood test results. I have been experiencing extreme fatigue, dizziness/vertigo, sensitivity to cold and gastro problems for the past few years. I have been searching for a reason, but my doctors say it's nothing. On a recent blood test, my B12 was 231 (ref. 211-911) and folic acid of 20. Since my folic acid is high and B12 towards the lower end, is it possible that I have a B12 deficiency?

Hello SandyES00, and Welcome to the boards! :wave:

Doctors commonly go by the low end of the range for B-12 deficiency, in your case it is 211 most go by 200. Meaning under 200 they will treat (and recognize deficiency) with RX IM injections of B-12. Your number is very low. You want to run around the top end of the range for B-12.

If you have PA a high intake of folate or folic acid can correct the anemia, but not the neuro symtoms related to this form of anemia. It can, *mask* the anemia and yet the neuro can go untreated and potentially become worse. This is what they mean by masking and many doctors will not check the B-012 until an anemia shows up on the CBC to begin with.:dizzy:

I cannot tell you that you have PA, you would need a doctor to DX this, usually a GI doc. I can tell you though that you should try to get them to RX injections for you to build your stores. You may want to make an appointment with a GI doc to do an Initial Eval for you. Were you DX'ed with anemia through a CBC? Have you had iron and Ferritin tested as well? Take care. FLFG

I was diagnosed with parkinsons disease one year ago, from slight tremor in right hand I now have a very bad constant tremor, also my right leg trembles and hurts my foot is numb and my hip hurts a lot, I am not on meds yet. Three months ago I was found to be b12 deficient the reading was 111, probably due to my alcohol intake, since feb I have had three injections of Hydoxocobalamin,has lightened my mood, but has done nothing for my symptoms, I wonder if I could just be b 12 deficient and not have parkinsons, even though I have classic symptoms, wonder if I had lots of injections of b 12 it would help, as I am sure all this was caused by my lack of b12, as I've had symptoms for maybe five years and not realised, or am I clutching at straws, I am British and live in the U.K.
