B12 injections

Posted , 4 users are following.

I had a partial gastrectomy 46 years ago and have been on monthly B12 injections since 1972. Suddenly  a few months ago my doctor changed it to ever 12 weeks and after blood tests showed I had a high B12 in my bloods. However, I am still very tired after 4 weeks does this mean that my body is not absorbing and how do I prove this so I may continue on a monthly basis.He put me on iron tablets as my levels were low.

    I suggest you follow the excellent advice Whitecross has given and join the Pernicious Anaemia Society who may well intercede with your doctor on your behalf.

    I am not medically trained but have also had a partial gastrectomy (in 1959) have P.A. and been on cyanocobamalin since 1972.

    I wish you well
