title: [Iron deficiency anaemia: clinical presentation, biological diagnosis and management].
abstract: The iron deficiency is the first cause of anaemia. In healthy young adult, anemia is well tolerated because of its progressive installation. The most common symptoms of anemia are pallor, fatigue and dyspnea. In biological exams, anemia is classically associated with microcytosis and hypochromia. The origins of microcytic anemia are iron deficiency, inflammatory aetiologies, thalassemia and sideroblastic anaemia. The iron-deficiency diagnosis includes two explorations: biological and clinical. The biological exploration is based on interpretation of serum biologics tests as blood iron, ferritin, transferrin with saturation, total iron-binding capacity and its soluble receptors. This interpretation is simple if it is not associated with clinical disorders influencing the internal iron cycle. The clinical exploration must always be followed by a careful assessment of the underlying cause as blood loss. The most common causes in women of reproductive age are gynaecologic. In men and menopausal women, the gastrointestinal tract bleeding is source of anemia. Therapeutic management of anemia is oral iron therapy. Etiological diagnostic of microcytosis is essential before iron therapy. If not, the treatment could be inefficient or it could mask or delay the etiological diagnostic.
