Which type of anemia is a result of vitamin B12 deficiency quizlet?
Pernicious anemia (PA), the most common type of macrocytic anemia, is caused by vitamin B12 deficiency.
Are pernicious anemia and B12 deficiency the same?
Technically, the term “pernicious anemia” refers to vitamin B12 deficiency due to a lack of intrinsic factor. Often though, vitamin B12 deficiency due to other causes also is called pernicious anemia.
What type of anemia is B12?
Pernicious anemia is a type of vitamin B12 anemia. The body needs vitamin B12 to make red blood cells. You get this vitamin from eating foods such as meat, poultry, shellfish, eggs, and dairy products. A special protein, called intrinsic factor (IF), binds vitamin B12 so that it can be absorbed in the intestines.
What is the type of anemia caused by an intrinsic deficiency of B12?
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.
What is the most common cause of vitamin B12 deficiency?
However, the most common cause of vitamin B-12 deficiency anemia is a lack of a substance called intrinsic factor, which can be caused when your immune system mistakenly attacks the stomach cells that produce this substance. This type of anemia is called pernicious anemia.
Which of the following is a result of vitamin B12 deficiency?

Why is my B12 low when I eat meat?
However, many people, no matter their age or diet, have “unexplained low vitamin B12 levels,” which researchers attribute to “food cobalamin malabsorption,” meaning the B12 that’s naturally present in foods like meat is simply not absorbed. The absorption process from oral ingestion is quite complex.
