(4) pregnancy and lactation: pregnancy due to the increase in blood volume and fetal development needs and loss of blood during childbirth and other reasons, iron deficiency almost inevitable. (5) intravascular hemolysis: paroxysmal nocturnal Hemoglobinuria, heart valve repair, because of excessive destruction of red blood cells, iron with hemoglobin, hemosiderosis from the urine from genistein, easy iron deficiency.
