Vitamin D Toxicity (Hypervitaminosis D) | Causes, Pathophysiology, Symptoms, Diagnosis, Treatment
***NOTE: I forgot to mention that in the diagnosis of Hypervitaminosis D, it is important to not only measure calcium (which will be high), vitamin D (which will also be high), but also to measure PTH (which will be LOW).***
Vitamin D Toxicity (Hypervitaminosis D) is a condition involving excessively high levels of vitamin D from either exogenous dietary sources or as produced from granulomatous conditions or lymphoma. Vitamin D Toxicity leads to hypercalcemia, which causes many of the symptoms observed in Vitamin D Toxicity. In this lesson, we also discuss how Vitamin D Toxicity is diagnosed and treated.
