Primary hyperparathyroidism

Primary hyperparathyroidism (PHPT) is the most common endocrine disease after diabetes mellitus (1 in 1500 hospital admissions) in adulthood as its age of presentation coincides with the second half of life(38). It is a clinical situation in which there is excessive secretion of PTH by the parathyroid glands, leading to chronic hypercalcaemia and alterations in the hormone's main target organs (kidney and bone)(5,6). It is the most common cause of hypercalcaemia in non-hospitalised patients(5,27).
