Anemia in adolescence. 2. Hemoglobinopathies and other causes.
Many complex forces are at work during adolescence which can contribute to the occurrence of anemia. Careful consideration of the entire patient should enable a physician to identify the unusual as well as the more common causes of anemia in this age group. Anemia in teenage girls is primarily due to menstrual iron loss. In boys, borderline diets and the demands of rapid growth predominate as causative factors. Hemoglobinopathies (thalassemia, sickle cell disease), G6PD deficiency, infectious mononucleosis, and illicit drug use account for small proportions of cases.
