Who Cannot absorb iron?

What causes a depletion of iron?
Common causes of iron deficiency include not getting enough iron in your diet, chronic blood loss, pregnancy and vigorous exercise. Some people become iron deficient if they are unable to absorb iron. Iron deficiency can be treated by adding iron-rich foods to the diet.
What happens when your iron is critically low?
Without enough iron, your body can’t produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath.
How much iron is too much?

What happens if you have too much iron?
Excessive iron can be damaging to the gastrointestinal system. Symptoms of iron toxicity include nausea, vomiting, diarrhea and stomach pain. Over time, iron can accumulate in the organs, and cause fatal damage to the liver or brain.
Can you pass out from low iron?

What causes refractory iron deficiency anemia in patients without gastrointestinal symptoms?

Does erythropoiesis stimulate iron absorption in chronic kidney disease?
Hyporesponsiveness to erythropoiesis stimulating agents in chronic kidney disease: the many faces of inflammation. . Effect of enhanced erythropoiesis on iron absorption. . Reduction in recombinant human erythropoietin doses by the use of chronic intravenous iron supplementation. .
What is the role of ferritin in the diagnosis of iron deficiency anemia?
Serum ferritin has the potential to differentiate true iron deficiency from inflammatory iron sequestration. However, both inflammation and intracellular iron accumulation stimulate the production of the iron storage protein ferritin whose soluble form is detectable in plasma and serum.
