What is megaloblastic anemia?

Also known as: Vitamin B12 deficiency anemia, folate-deficiency anemia, folic acid deficiency anemia, pernicious anemia.

Megaloblastic anemia is a type of anemia where the bone marrow produces fewer and abnormally large, oval shaped (instead of round/disk-like) red blood cells, with underdeveloped inside contents (hemoglobin). They tend not to survive as long as normal red blood cells.
