Does B12 Deficiency automatically mean Pernicious Anaemia?

Posted , 4 users are following.

Hi, last few months I've been suffering from fatigue, lethargy, depression, mild memory issues etc. recently got my blood tested for B12 and my levels were 100 against what I believe is a normal range of atleast 400. I've been advised B12 injections every alternate day for 5 days then every week for 5 weeks then every month for a year. Does this dosage seem right? Also how do I know I don't have PA? My MCH is high at 32.7 (against a normal at 32). Also are there any alternatives to taking the B12 shots and how do I make sure I'm not dependent on them life long?

    Don't usually say doctors are right but B12 can sort out lots of those problems for you. It's a wait and see thing really. Could tell you lots of stories where this works for clients. One of the success stories of modern medicine. I would say you would probably need this for life but is no big thing once every three months or so. Can make a huge difference to your life.

    The only thing I would say is docs will usually only do this every 12 weeks as recommended generally but some people need it every 10 or even 8 weeks to feel well. I had to argue and be a bother for months to get my mum who is 89 to have it at 10 weeks as she wend down rapidly after 8. It CAN be given more often than the stated 12 but you do have to tough it out to get it. Good luck....this is not a nasty thing, really.

    My Dr, today, rang me with the diagnosis of vitamin b12 deficiency. I wanted to ask him all your questions - where pernicious anaemia came into it etc. but didn't!. I will be having my first injection tomorrow morning. A course of three this week and three the next. Ater that one every three months. Hopefully, I'll get some answers from the nurse who is doing the injections. But having read "Tiny T" reply to you I am feeling less concerned. Good luck

    Hi Shubha,

    There's lots of information about B12 on the Pernicious Anaemia Society website, also Phoenix Rising, in the forums. You can have low B12 without having pernicious anaemia, that means you can't absorb it properly. There's a couple of tests that can be done to see if that's the case.
