According to Lorenzi (2005), in the practical one, for approach, it can be said less that a patient is anmico when presents less of 11g of hemoglobina for 100mL of blood (11g/dL) for woman and child and, of 12/100mL (12g/dL) for the man. It must, however, be added to this criterion, that the funcionante and not unnatural hemoglobina either (goal-hemoglobina, carboxi-hemoglobina or sulfa-hemoglobina) and that the sanguine either normal volume. In accordance with Oliveiras (2007), the anemias can occur for diverse etiolgicos factors. However, the anemias lacks (deficiency of iron, B12 vitamin and folatos) if detach as most common, after the anemias for sanguineous loss. The iron is an essential nutrient to the organism, associated with the red globule production and the transport of oxygen of the pulmes for all the cells of the body. The anemia for iron deficiency, or ferropriva anemia, is the most common of all nutricionais anemias, independently of the socioeconmico estrato of the individual.

Of agreement with Oak, Baracat and Sgarbieri, (2006, p.54)? the anemia for iron deficiency is separately, most common of the nutricionais deficiencies of the world and occurs as resulted of chronic sanguineous loss, urinrias losses, ingestion and/or deficient absorption and increase of the sanguineous volume? , as well as with the increase of the consumption, as it is the case of the gestantes. For the initial detention of anmico picture she is necessary to carry through a detailed analysis of the hemograma through the eritrocitria ancestry (red series of the blood) (PINE et al., 2008). Whereas the dosages of iron and srica ferritina guarantee the ferropriva etiology of the anemia. THEORETICAL REFERENCIAL 1. ANEMIA the anemia is a problem of public health, being characterized for the reduction of the funcionante total hemoglobina in the circulation.
