Iron deficiency
What proportion of women are iron deficiency in their reproductive years
20%

↓120 g/l
What is Hepcidin?
25-amino acid peptide hormone that regulates iron uptake and release from stores in response to circulating and tissue levels of iron.
Ferric iron (Fe2+) and ferrous iron (Fe3+), which iron is better absorbed from the guy
Ferric iron FE2+
For every ml of blood lost, how much iron is lost?

1.2g/l days
Continue for 3 months
