ABSTRACT

The iron is one of the most abundant elements on Earth, in humans it participates in many biological processes. During pregnancy the iron requirement is increased, and the mother’s placenta is the way through to provide the supply to the fetus. Worldwide, 40% of pregnant women suffer anemia. Therefore, their maternal-fetal metabolism plays an important part in the understanding of the pathophysiology of the disease and possible therapy. The low intake, predisposition and inadequate supplementation are factors that intervene in the high prevalence of anemia and iron deficiency in this stage of life. In this review article, we will describe the epidemiology, metabolism and main mechanisms by which the deficiency of the most important metal of biological systems is led: iron.
