Disorders of Zinc Metabolism: Causes, Symptoms, and Treatment

Zinc is an essential mineral that plays a crucial role in various biological processes, including growth and development, immune function, and wound healing. However, like other essential minerals, zinc can also cause problems if it is not adequately metabolized. Several disorders of zinc metabolism can affect individuals, resulting in various symptoms and complications.

1. Zinc Deficiency: Zinc deficiency is the most common disorder of zinc metabolism. It occurs when there is a lack of zinc in the body due to inadequate dietary intake, impaired absorption, or increased losses. Symptoms of zinc deficiency include impaired growth and development, delayed wound healing, skin rashes, and impaired immune function.
2. Acrodermatitis Enteropathica: Acrodermatitis enteropathica is a rare genetic disorder that affects zinc absorption. It results in skin lesions, diarrhea, and impaired growth and development. Infants with this disorder may not respond to zinc supplements and require high doses of zinc for treatment.
3. Wilson's Disease: Wilson's disease is a rare genetic disorder that affects copper metabolism. However, it can also cause problems with zinc metabolism, leading to zinc deficiency. Symptoms of Wilson's disease include liver disease, neurological problems, and psychiatric disorders.
4. Zinc Toxicity: Zinc toxicity occurs when there is an excess of zinc in the body. It can result from excessive zinc supplementation or exposure to zinc in the workplace. Symptoms of zinc toxicity include nausea, vomiting, abdominal pain, and diarrhea. Long-term zinc toxicity can also lead to copper deficiency and neurological problems.

Treatment for disorders of zinc metabolism depends on the underlying cause. Zinc deficiency is typically treated with zinc supplements, while acrodermatitis enteropathica requires high doses of zinc supplements. Wilson's disease is treated with medications that remove excess copper from the body, which can also help restore zinc metabolism. Zinc toxicity is treated by stopping zinc supplementation or removing the source of exposure.

In conclusion, disorders of zinc metabolism are relatively rare but can cause significant problems. Zinc deficiency is the most common disorder and can result from inadequate dietary intake or impaired absorption. Acrodermatitis enteropathica and Wilson's disease are rare genetic disorders that affect zinc metabolism. Zinc toxicity can occur from excessive supplementation or exposure to zinc in the workplace. If you suspect that you have a disorder of zinc metabolism, consult with your healthcare provider for proper diagnosis and treatment.
