Iron deficiency may result in a low white blood count and a high or low platelet count, according to the American Society of Hematology, or ASH. Iron is important in the production of hemoglobin and is essential for healthy cells, skin, hair and nails.
With a lack of iron, the body cannot produce enough oxygen-carrying hemoglobin for red blood cells, resulting in iron-deficiency anemia, notes WebMD.
Increasing iron intake may involve switching to a diet that is high in iron or taking intravenous or medicinal iron. Red blood cell transfusions may be required, typically for patients with severe iron deficiency who are actively bleeding or have significant symptoms, such as chest pain, shortness of breath or weakness, according to the ASH.
