title: Primary, secondary, and tertiary hyperparathyroidism.
abstract: Primary, secondary, and tertiary hyperparathyroidism have evolved since their original description. What was once a debilitating disease has now become one with few symptoms on initial presentation. Complications from these disorders have decreased significantly because of earlier detection. Improved management of patients with chronic renal disease has also limited complications among those with secondary and tertiary hyperparathyroidism. Appropriate management is essential even in the early phase of the disorder to minimize the morbidities that may result if left untreated.
