caused by blood loss, hemolytic anemiaand aplastic anemia.
Nutrient-deficiency andietary deficiency of fundamentalemia is cause d by
nutrients for the production orfunctioning of the red blood cells, like (^)
iron (iron deficiency anemia), vitamin
B12 and folic acid.
Anemia caused by blood loss occurs in

Hemolyticexcessive destruction of red blood cells, anemia is caused by (^)
for example, in hypervolemic conditions (in diseases like malaria orexcessive
water in blood that causes lysis of red
blood cells).
