Frequently Asked Questions
What causes low iron saturation?
Low iron saturation results from iron deficiency, chronic disease, and inflammation. High iron saturation is caused by hemochromatosis, iron supplementation, liver disease, and ineffective erythropoiesis.
Is low iron saturation dangerous?
Very low iron saturation causes symptomatic anemia. Persistently high saturation (above 60%) leads to iron deposition in the liver, heart, and pancreas, causing cirrhosis, cardiomyopathy, and diabetes.
