A member asked:
I was wondering is b12 deficiency the same as pernicious anemia?
A doctor has provided 1 answer
Related: Technically, pernicious anemia (pa) is due to low B12 levels caused by changes in the stomach resulting in decreased ability to absorb the B12 from a lack of something called "intrinsic factor." there are other causes of B12 deficiency that technically are not pa. Today, tests can find B12 deficiency before someone has symptomatic anemia so deficiency by itself is not always pa.
