Editing Iron overload (section)

===Secondary hemochromatosis===
* Severe chronic [[haemolysis|hemolysis]] of any cause, including intravascular hemolysis and [[ineffective erythropoiesis]] (hemolysis within the [[bone marrow]])
* Multiple frequent [[blood transfusion]]s (either whole blood or just [[red blood cell]]s), which are usually needed either by individuals with hereditary [[anaemia]]s (such as [[Thalassemia#Beta (?) thalassemias|beta-thalassaemia major]], [[sickle cell anaemia]], [[Diamond–Blackfan anaemia]]), or by older patients with severe acquired anaemias such as in [[myelodysplastic syndrome]]s.<ref name="Selective iron deposition in pancre"/>
* Excess parenteral (non-ingested) iron supplements, such as what can acutely happen in [[iron poisoning]]
* Excess dietary iron (i.e. [[African iron overload]])
* Some disorders do not normally cause hemochromatosis on their own, but may do so in the presence of other predisposing factors. These include [[cirrhosis]] (especially related to [[alcohol use disorder]]), alcoholic [[steatohepatitis]], prolonged [[haemodialysis|hemodialysis]], and post-[[portacaval shunt]]ing
