The red blood cells carry oxygen to and from muscles and tissues in the body. If a person has low iron levels, they may not send enough oxygen to their muscles. Muscles that are low in oxygen cannot burn fat for fuel as well as they should. Low iron also interferes with optimum metabolism in the body.

What is iron metabolism disorder?
Iron metabolism disorders may involve a number of genes including HFE and TFR2. Hepcidin is the master regulator of iron metabolism and, therefore, most genetic forms of iron overload can be thought of as relative hepcidin deficiency in one way or another.
What removes iron from the body?

- Chelation. Iron chelation therapy involves taking oral or injected medicine to remove excess iron from the body. …
- Dietary changes. Dietary changes to limit iron intake can help reduce symptoms.
What is needed for iron metabolism?
To be absorbed, dietary iron can be absorbed as part of a protein such as heme protein or iron must be in its ferrous Fe2+ form. … Hephaestin, a ferroxidase that can oxidize Fe2+ to Fe3+ and is found mainly in the small intestine, helps ferroportin transfer iron across the basolateral end of the intestine cells.
Does Iron cause weight gain?
Patients who receive iron treatment gain weight, if they do not make diet or have a metabolic disease. So, iron therapy increases serum ferritin levels accompanying with body weight. Our study results are consistent with this hypothesis, which was supported by other published studies as well.

Iron homeostasis is closely regulated via intestinal absorption.

What happens if I get too much iron?
