Increase in hepcidin. Medical search. Frequent questions

During conditions in which the hepcidin level is abnormally high, such as inflammation, serum iron falls due to iron trapping within macrophages and liver cells and decreased gut iron absorption. (wikipedia.org)
When the hepcidin level is abnormally low such as in hemochromatosis, iron overload occurs due to increased ferroportin mediated iron efflux from storage and increased gut iron absorption. (wikipedia.org)
Hepcidin is a 25-amino acid peptide hormone produced mainly in the liver that regulates intestinal iron absorption by causing degradation of the enterocyte iron transporter ferroportin, iron recycling by macrophages, and iron release from hepatic stores [ 4 , 6 ]. (biomedcentral.com)
