In Wilson's disease, copper isn't eliminated properly and instead accumulates, possibly to a life-threatening level. Symptoms typically begin between the ages of 12 and 23. Symptoms include swelling, fatigue, abdominal pain and uncontrolled or poorly coordinated movements. Treatment often includes medication that can prompt the organs to release copper into the bloodstream. Once it's in the bloodstream, it can then be eliminated from the body through the kidneys.
