Wilson disease is a rare inherited disorder that prevents your body from getting rid of extra copper. You need a small amount of copper from foodto stay healthy. Too much copper is poisonous. Normally, your liver releases extra copper into bile, a digestive fluid.
With Wilson disease, the copper builds up in your liver, and it releases the copper directly into your bloodstream. This can cause damage to your brain, kidneys, and eyes. It is present at birth, but symptoms usually start between ages 5 and 35. It first attacks the liver, the central nervous system or both. The most characteristic sign is a rusty brown ring around the cornea of the eye.
Treatment is with drugs to remove the extra copper from your body. You need to take medicine and follow a low-copper diet for the rest of your life. Don't eat shellfish or liver, as these foods may contain high levels of copper. At the beginning of treatment, you'll also need to avoid chocolate, mushrooms, and nuts. Have your drinking water checked for copper content and don't take multivitamins that contain copper.
