Iron deficiency, iron overload and the anemia of inflammation are the commonest iron-related disorders. While at least four types of hereditary iron overload have been identified to date, Iron absorption is upregulated by iron deficiency and increased erythropoiesis, and downregulated in inflammation and iron repletion, mediated by the recently described regulator of iron homeostasis, hepcidin, which blocks iron release from enterocytes and macrophages.2 Body iron stores are regulated through iron absorption.

with other causes of anemia,especially iron deficiency. The presence and type of anemia is established by a complete blood cell (CBC) count,reticulocyte count, and iron studies (Table 1). The laboratory tests will determine not only the structural characteristics but also the severity of the ane-mia.Most anemias initially present as normocytic.As they progress,different characteristics become In some cases (e.g., iron deficiency), etiologic classification is easily attained; in others (e.g.. aplastic anemia) the biochemical mechanism of disease may be hopelessly elusive.

Iron deficiency anemia may be classified into 3 stages: storage iron deficiency, iron deficient erythropoiesis, and iron deficiency anemia (1,2). Initially during blood loss, iron body stores are preferentially utilized for accelerated erythropoiesis. After depletion of body iron stores, erythropoiesis and production of other iron-containing proteins (such as myoglobin) become limited, leading 106 icant number of patients exhibit iron defiВ­ ciency anemia that can be overlooked if iron status is not carefully assessed.
