Holistic Hypercalcemia

Abstract

Vitamin D deficiency has recently been recognized to be highly prevalent, and multiple studies have implicated vitamin D deficiency in many nonskeletal conditions, including autoimmune diseases. This has resulted in a pendulum swing to high-dose vitamin D supplementation and the widespread perception that if vitamin D is good, more must be better. This view has unfortunately led to its own collection of adverse events. The following case report is an example of how this misperception can lead to an apparent endocrine disorder with potential for severe, even life-threatening, sequelae.
