    Area of Science:

    • Clinical Medicine
    • Toxicology
    • Nutritional Science

    Background:

    • Vitamin A is commonly prescribed for acne treatment.
    • Excessive vitamin A intake can lead to hypervitaminosis A.
    • Health foods contribute to potential overconsumption of vitamins.

    Observation:

    • Hypervitaminosis A presents with diverse clinical features.
    • Hypercalcemia is a notable, though rare, symptom of hypervitaminosis A.
    • Previous cases of hypercalcemia linked to hypervitaminosis A are limited.

    Findings:

    • Hypervitaminosis A can result from excessive vitamin A for sunburn prevention and minimal brain dysfunction treatment.
    • The syndrome should be considered in patients with hypercalcemia and liver dysfunction.
    • Increased availability of health foods may increase the risk of vitamin A toxicity.

    Implications:

    • Clinicians should consider hypervitaminosis A in patients with unexplained hypercalcemia and liver issues.
    • Awareness of hypervitaminosis A is crucial given the prevalence of vitamin A supplementation.
    • Early diagnosis and management of hypervitaminosis A can prevent severe health consequences.
