This phenomenon is professionally called hemochromatosis. It is a condition that is caused by excessive intake of iron from food or food supplements. This disease can even be hereditary and occurs more often in men aged 40 to 60 years. It is caused by the accumulation of iron in the blood, while its efficient absorption does not occur. Hemochromatosis can be a symptom of another disease - liver disease, kidney disease, frequent blood transfusions or alcoholism. The main store of iron in the body is the liver, which is why it is most often damaged by an excessive amount of ferritin.
