Impacto da doação de sangue nos depósitos de ferro do organismo de doadores

Iron is a vital element in the human metabolism. It plays a central role in erythropoiesis and is also involved in many other intracellular processes in all the tissues of the body. Blood donation results in a substantial (200 to 250 ng) loss of iron at each donation (425 to 475 ml) with subsequent mobilization of iron from body deposits. Repetitive donations of blood my cause the depletion of iron reserves in blood donors and thus cause health disorders. Recent reports have shown that iron reserves are generally small and iron depletion is more common in blood donors than in non-donors. The h...
