Answer:
What is pernicious anemia?
Anemia is a medical condition in which the blood is low in normal red blood cells.
Pernicious anemia is one cause of vitamin B-12 deficiency anemia. It’s thought mainly to be caused by an autoimmune process that makes a person unable to produce a substance in the stomach called intrinsic factor.
This substance is needed to absorb dietary vitamin B-12 in the small intestine. Vitamin B-12 is a required nutrient that helps allow proper red blood cell production and function in the body.
Pernicious anemia is a rare condition, with a prevalence of 0.1 percent in the general population and 1.9 percent in people who are older than 60 years, according to a 2012 studyTrusted Source in the Journal of Blood Medicine.
