Iron-deficiency anemia is anemia caused by a lack of iron. Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. When onset is slow, symptoms are often vague, including feeling tired, weakness, shortness of breath, or poor ability to exercise. Anemia that comes on quickly often has greater symptoms, including: confusion, feeling like one is going to pass out, and increased thirst. There needs to be significant anemia before a person becomes noticeably pale. Problems with growth and development may occur in children. There may be additional symptoms depending on the underlying cause.
Iron-deficiency anemia is usually caused by blood loss, insufficient dietary intake, or poor absorption of iron from food.
Prevention is by eating a diet high in iron or iron supplementation in those at risk. Treatment depends on the underlying cause and may include dietary changes, medications, or surgery. Iron supplements and vitamin C may be recommended. Severe cases may be treated with blood transfusions or iron injections.
Iron-deficiency anemia affected about 1.48 billion people in 2015. A lack of dietary iron is estimated to cause approximately half of all anemia cases globally. Women and young children are most commonly affected. In 2015 anemia due to iron deficiency resulted in about 54,000 deaths – down from 213,000 deaths in 1990.
Anemia can be diagnosed with a blood test by finding out if there is little enough hemoglobin in the blood.
