What electrolyte abnormality is commonly associated with sarcoidosis?

In the context of sarcoidosis, hypercalcemia is a common and significant electrolyte abnormality. This condition often occurs due to the increased production of calcitriol (active vitamin D) by activated macrophages within the granulomas typical of sarcoidosis. As a result, patients with sarcoidosis may experience elevated serum calcium levels, which can lead to various symptoms, including fatigue, weakness, and, in severe cases, kidney dysfunction due to hypercalcemia-related complications.

The mechanism linking sarcoidosis to hypercalcemia illustrates how systemic inflammatory processes can impact calcium homeostasis, making it a critical aspect of the disease's clinical management. Monitoring calcium levels in patients diagnosed with sarcoidosis is essential to prevent potential complications associated with elevated calcium levels.
