Iron is an essential part of hemoglobin, the oxygen-carrying component of blood. Ppl with iron deficiencies tire easily from the lack of oxygen.So when you lose a lot of blood in a surgery, you will be on iron supplements in the hospital because you lost a lot of blood.my physiology understanding is a little off. maybe you can explain the whole hemoglobin/iron thing to me again and why a patient would be on iron after surgery. what exactly would it do? raise RBCs? Hemoglobin/hematocrit? how?
