Wilson Disease is an inherited condition that causes the body to retain excess copper. The liver of a person who has Wilson Disease does not release copper into bile as it should. As the copper builds up in the liver, it begins to damage the organ.
After enough damage, the liver releases the copper directly into the bloodstream, which carries the copper throughout the body. The copper buildup leads to damage in the kidneys, brain, and eyes. If not treated, Wilson Disease can cause severe brain damage, liver failure, and death.
