Untreated, hereditary hemochromatosis can lead to a number of complications, especially in your joints and in organs where excess iron tends to be stored — your liver, pancreas and heart. Complications can include:
Liver problems. Cirrhosis — permanent scarring of the liver — is just one of the problems that may occur. Cirrhosis increases your risk of liver cancer and other life-threatening complications.
Pancreas problems. Damage to the pancreas can lead to diabetes.
Heart problems. Excess iron in your heart affects the heart's ability to circulate enough blood for your body's needs. This is called congestive heart failure. Hemochromatosis can also cause abnormal heart rhythms (arrhythmias).
Reproductive problems. Excess iron can lead to erectile dysfunction (impotence), and loss of sex drive in men and absence of the menstrual cycle in women.
Skin color changes. Deposits of iron in skin cells can make your skin appear bronze or gray in color.
