I am female (48) in UK - A blood test showed I had low B12 so, after initial loadng doses, I was put on 12 weekly injections. Since I have also stopped absorbing calcium so have to take vitamin D to help absorption.
Question is how do I find out why and whether there is an underlying issue?
I have not been offered any tests as initially was told they weren't covered on the NHS. I have private healthcare so would like to understand my options and what to ask for when I see my GP. Can anyone advise? Many thanks
