Iron Toxicity
Iron toxicity can be either sudden or gradual. Many serious health problems may be caused by accidental overdoses, taking high-dose supplements for a long time, or chronic iron overload disorders. Under normal circumstances, very little free iron circulates in the bloodstream. It is safely bound to proteins, such as transferrin, which keep it from causing harm. However, iron toxicity can significantly increase the levels of "free" iron in the body. Free iron is a pro-oxidant - the opposite of an antioxidant - and may cause damage to cells. Several conditions may cause this to happen. These include: - Iron poisoning: Poisoning can occur when people, usually children, overdose on iron supplements (5, 6).
- Hereditary hemochromatosis: A genetic disorder characterized by excessive absorption of iron from food (7).
- African iron overload: A type of dietary iron overload caused by high levels of iron in food or drinks. It was first observed in Africa, where homemade beer was brewed in iron pots (8).
Acute iron poisoning happens when people overdose on iron supplements. Single doses as low as 10–20 mg/kg may cause adverse symptoms. Doses higher than 40 mg/kg require medical attention (9). Similarly, repeated high-dose iron supplementation may cause serious problems. Make sure to follow the instructions on iron supplements, and never take more than your doctor recommends. Early symptoms of iron poisoning may include stomach pain, nausea and vomiting. Gradually, the excess iron accumulates in internal organs, causing potentially fatal damage to the brain and liver. The long-term ingestion of high-dose supplements may gradually cause symptoms similar to iron overload, which is discussed more below.
