Disorders of Zinc Metabolism: An Overview

Zinc is an essential mineral that plays a crucial role in various physiological processes in the human body. It is involved in over 300 enzymatic reactions, contributing to functions like immune response, DNA synthesis, cell division, and wound healing. While zinc deficiency is a well-known issue, disorders of zinc metabolism can also occur, leading to various health complications.

Here are some common disorders of zinc metabolism:

1. Zinc Deficiency: Insufficient intake or impaired absorption of zinc can lead to zinc deficiency. This condition can result from dietary inadequacy, chronic illnesses, malabsorption disorders, or certain medications. Zinc deficiency can cause symptoms such as growth retardation, delayed sexual maturation, impaired immune function, hair loss, and skin changes.
2. Zinc Transporter Deficiency: Zinc transporter proteins are responsible for moving zinc across cell membranes. Mutations in genes encoding these transporters can disrupt zinc transport, leading to zinc transporter deficiency. This condition can cause symptoms like growth retardation, intellectual disabilities, impaired immune function, and skin disorders.
3. Acrodermatitis Enteropathica: Acrodermatitis enteropathica is a rare autosomal recessive disorder characterized by impaired zinc absorption. It results in zinc deficiency despite adequate dietary zinc intake. This condition is typically observed in infants and young children, manifesting as a skin rash, diarrhea, growth retardation, and hair loss.
4. Low Serum Zinc: Low serum zinc levels can occur due to various factors, including inadequate dietary intake, malabsorption, chronic liver or kidney disease, and certain medications. Low serum zinc levels can affect wound healing, immune function, and contribute to the development of other health issues.
5. Excess Zinc: While zinc deficiency is more common, excessive zinc intake can also be problematic. High levels of zinc can interfere with copper absorption, leading to copper deficiency. Symptoms of excess zinc intake may include nausea, vomiting, diarrhea, abdominal pain, and impaired immune function.

It is important to note that diagnosing disorders of zinc metabolism requires medical evaluation and testing. If you suspect any zinc-related issues, consult a healthcare professional for proper diagnosis and guidance.

Understanding disorders of zinc metabolism is crucial for maintaining optimal health. While treatment options exist for these conditions, they are beyond the scope of this article. Stay tuned for more information on the prevention and management of zinc-related disorders.
