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 ...
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.
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 diagnosis of hyperphosphatemia is made through measuring the concentration of phosphate in the blood. A phosphate concentration greater than 1.46 mmol/L (4.5 mg/dL) is indicative of hyperphosphatemia, though further tests may be needed to identify the underlying cause of the elevated phosphate levels.

Testosterone is an essential hormone for both men and women, playing an important role in muscle growth and cognitive function. Low levels of the hormone can lead to changes in mood, cognition and ...
Tertiary hyperparathyroidism is defined by autonomous release of parathyroid hormone while in a hypercalcaemic state. Unlike primary hyperparathyroidism, hypercalcemia in the tertiary form is thought to be the result of resolution of secondary hyperparathyroidism rather than adenoma formation alone.
I advise women not to do it, because it can cause false reassurance or needless anxiety.” And there’s one more red flag (in case you needed one): Your AMH number changes all the time.
