Wilson Disease: Managing Copper Buildup and Protecting Vital Organs

Wilson disease is a rare, inherited condition that disrupts how the body processes copper. While copper is essential in tiny amounts for healthy nerves and bones, people with this disorder cannot eliminate the excess. This leads to toxic accumulation that primarily targets the liver and the central nervous system.

The Mechanism of Copper Toxicity

In a healthy body, the liver filters extra copper and releases it into bile to be excreted. In Wilson disease:

Storage Failure: The liver becomes overloaded and begins releasing copper directly into the bloodstream.
Systemic Damage: Once in the blood, the copper travels to and damages the brain, kidneys, and eyes.
Onset: Although the condition is present from birth, symptoms typically emerge between the ages of 5 and 35.

Recognizing the Signs

The most distinct clinical sign of Wilson disease is the Kayser-Fleischer ring—a rusty brown ring that appears around the cornea of the eye. Other symptoms depend on whether the copper is attacking the liver (causing jaundice or fatigue) or the nervous system (causing tremors or coordination issues).

Diagnosis involves:

A comprehensive physical examination.
Specialized laboratory tests to measure copper levels in the blood and urine.

Life-Long Management and Diet

While there is no cure, Wilson disease is highly manageable with consistent treatment.

Medical Treatment

Patients are prescribed “chelating agents,” which are drugs that bind to copper and help the body flush it out through the kidneys.

Dietary Restrictions

A low-copper diet is a lifelong requirement. Key guidelines include:

Strictly Avoid: Shellfish and liver.
Initial Restrictions: Chocolate, mushrooms, and nuts should be avoided during the early stages of treatment.
Environmental Checks: Drinking water should be tested for copper content, and multivitamins containing copper must be avoided.
