Symptoms of iron overload include chronic fatigue, sexual dysfunction, joint pain, depression and hair loss, according to the Iron Disorders Institute. In addition to elevated iron levels, patients with iron overload typically have elevated liver enzymes and blood sugar.
Excess amounts of iron in vital organs increase a person's risk for heart failure, osteoporosis, osteoarthritis, liver disease, metabolic syndrome and diabetes mellitus, notes the Iron Disorders Institute. Genetic disorders that cause iron overload include hereditary hemochromatosis, sickle cell disease, enzyme deficiencies and rare protein transport disorders. Treatment options for iron overload include using iron chelator drugs to remove excessive iron from the body or having blood taken out of the body, typically every few weeks, reports the Aplastic Anemia & MDS International Foundation.
