Wilson's Disease
What is Wilson's disease?
Wilson's disease is a rare genetic disorder that causes copper to build up in your body. Your liver normally filters out extra copper and sends it into bile for removal. When you have Wilson's disease, your body cannot remove extra copper properly. The copper accumulates in your liver, brain, eyes, and other vital organs over time.
This condition is inherited, meaning you get it from both parents. Each parent carries one copy of the faulty gene but usually has no symptoms. If you inherit two faulty copies, one from each parent, you develop Wilson's disease. The condition typically appears between ages 5 and 35, though it can show up at any age.
Without treatment, Wilson's disease can cause serious liver damage, neurological problems, and psychiatric symptoms. Early detection and treatment can prevent most complications. With proper care, most people with Wilson's disease live normal, healthy lives.
Symptoms
- Fatigue and weakness that does not improve with rest
- Jaundice, a yellowing of the skin and eyes
- Abdominal pain or swelling in the belly area
- Tremors or uncontrolled movements in hands or arms
- Difficulty walking, speaking, or swallowing
- Stiffness or rigidity in muscles
- Behavioral changes, depression, or anxiety
- Problems with memory or concentration
- Golden or brownish rings around the iris called Kayser-Fleischer rings
- Nausea, vomiting, or loss of appetite
Some people have no symptoms in the early stages. Others may only have liver symptoms or only neurological symptoms at first. The disease progresses slowly in most cases, making early signs easy to miss.

Causes and risk factors
Wilson's disease is caused by mutations in the ATP7B gene. This gene provides instructions for making a protein that moves copper from the liver into bile. When the gene does not work properly, copper stays in the liver instead of leaving the body. Over time, the copper damages liver cells and spills into the bloodstream, traveling to the brain, kidneys, and eyes.
You can only get Wilson's disease if you inherit two copies of the faulty gene, one from each parent. People who carry only one copy are called carriers and typically have no symptoms. Risk factors include having a family history of Wilson's disease or being of Eastern European, Mediterranean, or Asian descent. The condition affects about 1 in 30,000 people worldwide.
How it's diagnosed
Doctors diagnose Wilson's disease using a combination of blood tests, urine tests, eye exams, and genetic testing. Blood tests can measure ceruloplasmin, a protein that carries copper in the blood. Low ceruloplasmin levels combined with high copper in urine suggest Wilson's disease. Liver function tests, including ALT, may show elevated levels indicating liver damage.
An eye exam can reveal Kayser-Fleischer rings, which are highly specific for Wilson's disease. A liver biopsy may be needed to measure copper levels directly in liver tissue. Genetic testing can confirm the diagnosis by identifying mutations in the ATP7B gene. If you have symptoms or a family history of Wilson's disease, talk to your doctor about specialized testing. Early diagnosis is critical for preventing permanent organ damage.
Treatment options
- Chelating agents like penicillamine or trientine that bind to copper and help remove it through urine
- Zinc supplements that block copper absorption from food in the intestines
- Low copper diet avoiding foods like shellfish, liver, mushrooms, nuts, and chocolate
- Regular monitoring of copper levels, liver function, and neurological status
- Liver transplant in cases of severe liver failure that do not respond to medication
- Physical therapy for movement problems or muscle stiffness
- Mental health support for depression, anxiety, or behavioral changes
Treatment is lifelong and must continue even after symptoms improve. Most people respond well to medication when started early. Stopping treatment can cause copper to build up again and damage organs. Work closely with a hepatologist or specialist experienced in treating Wilson's disease.
Frequently asked questions
The first signs vary by person and age. In children and teenagers, liver problems like fatigue, jaundice, or abdominal pain often appear first. In young adults, neurological symptoms such as tremors, difficulty speaking, or personality changes may be the first sign. Some people have no obvious symptoms until copper buildup causes serious organ damage.
Wilson's disease is not curable, but it is highly treatable. Lifelong medication can remove excess copper and prevent new buildup. Most people who start treatment early can avoid serious complications and live normal lives. Treatment must continue for life, even when symptoms disappear, to prevent copper from accumulating again.
Wilson's disease follows an autosomal recessive pattern. You must inherit two faulty copies of the ATP7B gene, one from each parent, to develop the disease. If both parents are carriers, each child has a 25% chance of having Wilson's disease, a 50% chance of being a carrier, and a 25% chance of inheriting two normal genes.
Avoid foods high in copper, especially during the first year of treatment. These include shellfish, liver and organ meats, mushrooms, nuts, chocolate, and dried fruit. Also avoid using copper cookware or drinking water from copper pipes. After copper levels stabilize, your doctor may allow small amounts of these foods occasionally.
Yes, copper buildup in the brain can cause serious neurological and psychiatric symptoms. These may include tremors, muscle stiffness, difficulty walking or speaking, personality changes, and depression. Brain symptoms usually appear in people between ages 20 and 30. Early treatment can prevent or reduce brain-related complications.
Kayser-Fleischer rings are golden or brownish rings that form around the colored part of the eye. They result from copper deposits in the cornea. These rings are present in about 95% of people with neurological symptoms from Wilson's disease. An eye doctor can see them during a special eye exam using a slit lamp.
After diagnosis, you need regular monitoring every few months initially. Your doctor will check copper levels in blood and urine, liver function tests, and medication levels. Once stable, testing may happen every 6 to 12 months. Lifelong monitoring ensures treatment is working and prevents complications from copper buildup or medication side effects.
Women with well-controlled Wilson's disease can have healthy pregnancies. Treatment must continue during pregnancy to prevent copper buildup, though medication may need adjustment. Work with both your Wilson's disease specialist and obstetrician throughout pregnancy. Most women on stable treatment have normal pregnancies and healthy babies.
Untreated Wilson's disease causes progressive liver damage leading to cirrhosis or liver failure. Copper buildup in the brain causes permanent neurological damage and psychiatric problems. The condition can also damage kidneys, heart, and joints. Without treatment, Wilson's disease is fatal, but early treatment prevents most complications.
Yes, all siblings of someone with Wilson's disease should be tested. They have a 25% chance of also having the condition. Parents and children should consider genetic counseling and carrier testing. Early detection in family members allows treatment to start before symptoms appear, preventing serious organ damage.
