This document discusses iron deficiency anemia, including signs, symptoms, causes, prevention and risk factors. It recommends seeing a doctor if anemia is suspected rather than self-diagnosing or treating, as excess iron can damage the liver. Symptoms include fatigue, pale skin and dizziness.

Prevention involves a diet with vitamins and nutrients, and those at risk include women, infants/children, vegetarians and frequent blood donors.
