Quizplus · Accepted Answer

Vitamin B12 deficiency anemia can result from a variety of causes, including inadequate dietary intake, malabsorption, and certain medications. Pernicious anemia is a type of vitamin B12 deficiency anemia that specifically results from the body's inability to absorb vitamin B12 due to a lack of intrinsic factor, a protein produced in the stomach. While pernicious anemia is one potential cause of vitamin B12 deficiency anemia, it is not the only one, and a person may have vitamin B12 deficiency anemia without having pernicious anemia.
