Hypercalcemia syndrome: differential diagnostic search and treatment tactics

Abstract

Hypercalcemia is a common laboratory finding. The most common causes of high blood calcium are primary hyperparathyroidism, tertiary hyperparathyroidism, parathyroid cancer, malignant neoplasms, long-term therapy with lithium and thiazide diuretics, vitamin D intoxication, which require a different approach to treatment. Therefore, it is important for a doctor to be able to conduct a differential diagnostic search for hypercalcemia syndrome in order to establish the cause of high blood calcium and determine the correct tactics for managing patients.
