Adding Iron to the Diet is a Successful Way to Treat

Question

Adding iron to the diet is a successful way to treat pernicious anemia.

Accepted Answer

Pernicious anemia is caused by a deficiency in vitamin B12, which is needed for the production of red blood cells. Iron is not effective in treating pernicious anemia because it is not a deficiency in iron. Treatment for pernicious anemia usually involves vitamin B12 injections or supplements.
