My mum has recently been diagnosed as having pernicious anemia and has been having injections of B12 as a result.
Her doctor has told her it is hereditary and if she has daughters they will have it too, so I apparently will develop it. (The doctor didn't seem to think it was a case of 'if', rather I 'will' develop it.)
Anyway, I have googled and found that pernicious anemia is an absence of the protein that helps the body absorb vit B12, or something like that. It can't be cured and if untreated can cause death.
What I was wondering was, should I be taking supplements of B12 now? Will it help? And should I see my doctor for a blood test? Or am I just being a hypochondriac because it doesn't seem to cause trouble until later life anyway...
