Megaloblastic Pernicious Anemia

What is megaloblastic anemia?

Megaloblastic anemia is a type of anemia characterized by very large red blood cells and a decrease in the number of those cells. Megaloblastic anemia is usually due to acquired deficiency in vitamin B12 or folic acid. The deficiency may be due to inadequate dietary intake of these B vitamins or poor intestinal absorption. In rare cases, megaloblastic anemia is caused by medications or inherited defects in the metabolism of vitamin B12 or folic acid.

Pernicious anemia is a type of megaloblastic anemia in which the body isn’t able to absorb vitamin B12 due to a lack of intrinsic factor in stomach secretions. Intrinsic factor is needed for the body to absorb vitamin B12.
