title: [Diagnostic approach to iron deficiency anemia].
abstract: Anemia affects a fourth of the global population, with iron deficiency remaining the primary cause. It is associated with diminished work capacity, fatigue, impaired cognitive function, and can negatively impact the course of diseases like chronic heart failure or chronic kidney disease. Treatment options include oral and intravenous iron; however, conditions such as inflammatory bowel disease, celiac disease, or autoimmune gastritis can diminish the efficacy of oral iron. Timely recognition of iron deficiency anemia and administration of appropriate therapy not only improves quality of life, but also reduces the need for blood transfusions. Proper selection of iron-deficient patients for whom further diagnostic testing is necessary facilitates identification of underlying diseases that require specific treatment, and avoids unnecessary invasive testing.
