A sobrecarga de ferro é o acúmulo de ferro em excesso nos tecidos do corpo. A sobrecarga de ferro geralmente ocorre como resultado de uma predisposição genética para absorver e armazenar ferro em quantidades excessivas, sendo a forma mais comum a hemocromatose hereditária. A sobrecarga de ferro também pode ocorrer como complicação de outros distúrbios hematológicos que requerem terapia de transfusão crônica, injeções repetidas de ferro parenteral ou ingestão excessiva de ferro. Os estoques excessivos de ferro geralmente se acumulam nos tecidos reticuloendoteliais e causam poucos danos (“hemossiderose”). Se a sobrecarga continuar, o ferro eventualmente começa a se acumular em tecidos como parênquima hepático, pâncreas, coração e sinóvia, causando hemocromatose. | |||
