|---|---|---|---|
| Features | Primary hyperparathyroidism | Secondary hyperparathyroidism | Tertiary hyperparathyroidism |
| Pathology | Hyperfunction of parathyroid cells due to hyperplasia, adenoma or carcinoma. | Physiological stimulation of parathyroid in response to hypocalcaemia. | Following long term physiological stimulation leading to hyperplasia. |
| Cause | |||
| Associations | May be associated with multiple endocrine neoplasia. | Usually due to chronic renal failure or other causes of Vitamin D deficiency. | Seen in chronic renal failure. |
| Serum calcium | High | Low/Normal | High |
| Serum phosphate | Low/Normal | High | High |
| Management | Usually surgery if symptomatic. Cincacalcet can be considered in those not fit for surgery. | Treatment of underlying cause. | Usually cinacalcet or surgery in those that don't respond. |
