Key Points about Zinc Deficiency:
- Definition: Zinc deficiency is a condition where there is insufficient zinc in the body, leading to a range of dermatological and systemic manifestations. Zinc is crucial for skin integrity, immune function, and wound healing.
- Causes:
- Nutritional: Inadequate dietary intake, particularly in populations relying on cereals or grains with low zinc bioavailability.
- Malabsorption: Conditions like Crohn’s disease or short bowel syndrome.
- Inherited: Acrodermatitis enteropathica, a genetic disorder affecting zinc absorption.
- Symptoms:
- Skin rashes, often around the mouth, genitals, and hands.
- Hair loss, poor wound healing, and skin infections.
- Diarrhoea and increased susceptibility to infections.
- Growth retardation in children.
- Diagnosis:
- Clinical examination of skin lesions and other symptoms.
- Serum zinc levels, though these can be an unreliable marker.
- Improvement after zinc supplementation can help confirm diagnosis.
- Management:
- Supplementation: Oral zinc supplements, with dosage depending on severity.
- Dietary modification: Increase intake of zinc-rich foods like meat, shellfish, and legumes.
- Treatment of underlying conditions contributing to malabsorption.
- Complications:
- Persistent skin lesions and infections if left untreated.
- Growth delays and impaired immune function in children.
- Long-term zinc deficiency can lead to more severe complications like delayed sexual maturation and cognitive deficits.
