Vitamin A is a commonly available supplement found naturally in many foods. While it is essential for numerous physiological processes, caution is required when supplementing at high doses, as excessive intake can result in vitamin A toxicity, which may present with hypercalcemia. We report a case of a patient who developed elevated calcium levels associated with excessive vitamin A consumption. This case highlights the importance of considering inappropriate vitamin A supplementation as a potential cause of hypercalcemia.
维生素A是一种常见的补充剂，天然存在于许多食物中。虽然它对众多生理过程至关重要，但高剂量补充时需谨慎，因为过量摄入会导致维生素A中毒，可能表现为高钙血症。我们报告一例患者，其钙水平升高与过量摄入维生素A有关。该病例凸显了将不适当的维生素A补充视为高钙血症潜在原因的重要性。
