hyperparathyroidism
Start with the big picture
Primary hyperparathyroidism typically reflects autonomous PTH production, often from an adenoma, and is associated with increased serum calcium and reduced phosphate. Secondary disease arises in settings such as chronic kidney disease, malabsorption, or vitamin D deficiency, with laboratory patterns shaped by the underlying cause. Tertiary hyperparathyroidism can develop after prolonged secondary disease, particularly in end-stage renal disease. Clinical features may involve bone, kidney, gastrointestinal, and neuropsychiatric systems. Evaluation combines biochemical testing with imaging for localization when appropriate. Management ranges from addressing contributing factors and using medical therapy to considering parathyroidectomy based on symptoms and clinical findings. The full lesson develops these distinctions and their monitoring implications.
What you'll learn
- Distinguish primary, secondary, and tertiary hyperparathyroidism by cause and biochemical pattern.
- Recognize common clinical manifestations and complications of excess PTH.
- Identify laboratory tests used to evaluate hyperparathyroidism.
- Describe factors that may support parathyroidectomy or medical management.
- Summarize monitoring concerns associated with selected therapies.
