I didn't like the word "acquired" at the time I was thinking about it.
Marre, Sorry about the bad translations. I was using one of the automatic translators on the internet. My dutch is pretty bad even though my heritage is dutch. The Swedish was even more interesting - Förvärvade B12-brist.
When I first heard "pernicious" it sounded cute and quaint. I think that is the initial reaction most people have. But when I looked up the meaning, it is truely the correct word that describes the damage that occurs from the B12 deficiency - no matter whether it is an autoimmune diaease, and acquired one, or a self inflected one. It is the powerful part of the name.
The article I found on the World Health Organisation provided me with a much better insight into how stomach acid and bile interact to continually reuse and recycle the B12 that is currently stored in the body. It is a product of a long evolution where everyone needed a continuous flow of B12 but the source - i.e. fresh meat - was sparse.

Thanks for your feedback.
Thanks, Paul - Riding the B12D roller coaster while challenged by dysgraphia (I correctly spell the wrong word when my B12 is low).
