Causas da toxicidade por vitamina D em idosos: uma revisão de relatos de casos

Abstract

With the aging process, an increase in vitamin D supplementation has been observed, but the indiscriminate use and without medical prescription can lead to intoxication and, consequently, to systemic changes. This is a narrative review of the literature with the aim of investigating the main causes of vitamin D poisoning in the elderly in case reports.The search for articles was performed in the electronic databases: Scientific Electronic Library on Line (SciELO), Latin American Literature (LILACS) and Google Scholar. The Descriptors in Health Sciences (DeCS): “Vitamin D” and “toxicity” were used, and case reports articles published between 2016 and 2021 were included. At the end of the selection of the most relevant publications, the results of 6 articles were interpreted. The most common signs and symptoms of vitamin D intoxication are weakness, nausea, vomiting, inappetence, weight loss. In addition to mental confusion, hypercalcemia and renal dysfunction. The results showed that vitamin D toxicity is due to inappropriate use by the patient, erroneous prescriptions and administrations and even an eventual manipulation error. Thus, special care must be taken in supplementation, and monitoring of the family and health professionals who accompany the patient is necessary.
