Symptoms of hyperparathyroidism are caused by inappropriately normal or elevated blood calcium excreted from the bones and flowing into the blood stream in response to increased production of parathyroid hormone. [1] In healthy people, when blood calcium levels are high, parathyroid hormone levels should be low.
Primary hyperparathyroidism (or PHPT) is a medical condition where the parathyroid gland (or a benign tumor within it) produce excess amounts of parathyroid hormone (PTH). ). The symptoms of the condition relate to the resulting elevated serum calcium (hypercalcemia), which can cause digestive symptoms, kidney stones, psychiatric abnormalities, and bone dis
Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia of these glands. This disorder is primarily seen in patients with chronic kidney failure.
The single major disease of parathyroid glands is overactivity of one or more of the parathyroid lobes, which make too much parathyroid hormone, causing a potentially serious calcium imbalance. This is called hyperparathyroidism ; it leads to hypercalcemia , kidney stones, osteoporosis, and various other symptoms.
Symptoms in tertiary hyperparathyroidism are generally those seen in relation to elevated blood calcium levels. [ 8 ] [ 1 ] Tertiary hyperparathyroidism shares many symptomatic features with that of primary hyperparathyroidism , as the two are defined by hypercalcemia.

Intact PTH (iPTH, biologically active parathyroid hormone molecules) is measured with immunoradiometric or immunochemoluminescent assay. Elevated (or high-normal) iPTH with high urine calcium/creatinine ratio (more than 0.03) is suggestive of primary hyperparathyroidism, usually accompanied by low serum phosphate.
The differently colored narrow arrows indicate where the specified hormones act, and their effects (“+” means stimulates; “-“ means inhibits) when their plasma levels are high. PTH is parathyroid hormone, 1,25 OH VIT D 3 is calcitriol or 1,25 dihydroxyvitamin D 3, and calcitonin is a hormone secreted by the thyroid gland when the plasma ...
