When there are not enough red blood cells, the tissues do not get enough oxygen and can’t work properly.<\/p>\n There are many different types of anemia, but the most common type is iron deficiency anemia. Iron deficiency anemia is caused by a lack of iron in the blood. Iron is needed to make hemoglobin, a protein in red blood cells that carries oxygen.
