Cry for help - can anyone recommend a gastroenterologist or a haematologist consultant with special interest in B12 deficiency? Ideally someone you had personal experience with in London/South East? I am borderline B12 deficient at the moment and was also quite deficient couple years ago. I’m also experiencing neurological symptoms but my GP won’t prescribe B12 injections as anti-intrinsic factor and MMA normal. Thank you.
