Secondary Iron Overload
Key Points
Secondary iron overload results from excess absorption of iron, repeated blood transfusions, or excess oral intake. The effects of secondary iron overload include liver disease (leading to cirrhosis), skin pigmentation, diabetes, arthropathy, erectile dysfunction, and sometimes heart failure. Diagnose by measuring serum ferritin level; if elevated, confirm by demonstrating elevated serum iron and transferrin saturation. Treat with chelation.
