[1] Normal calcium homeostasis depends on a complex set of hormonal regulatory mechanisms that include the effects of parathyroid hormone (PTH), vitamin D metabolites, and calcitonin on calcium transport in bone, kidneys, and the gastrointestinal tract
Treatment usually includes: Oral calcium

Higher blood phosphorus levels The kidneys cannot make active vitamin D (needed to absorb calcium) Lower blood calcium levels Secondary hyperparathyroidism can
Parathyroid hormone decreases phosphate reabsorption at the proximal convoluted tubule
Synthesis and secretion of FGF23 by osteocytes are positively regulated by 1,25 (OH) 2 D and serum phosphorus and negatively regulated, through yet unknown mechanisms, by

While calcium plays a role in blood clotting as well as muscle, heart, and nerve function, phosphorus helps the body store energy

Hypoparathyroidism is usually a chronic (lifelong) condition, but it can be temporary
Primary hyperparathyroidism – this occurs when too much parathyroid hormone is produced from over growth and over excessive function of one or more of the parathyroid glands
This makes blood calcium levels fall (hypocalcaemia) and blood phosphorus levels rise (hyperphosphataemia), which can cause a wide range of symptoms, including
Your body's levels of calcium, vitamin D and phosphorus all need to be in balance
Secondary Hyperparathyroidism, when certain medical conditions skew the levels of calcium and a related mineral, phosphate
First described in 1985 by Tieder , this inherited disease is characterised by decreased renal Pi reabsorption, hypophosphataemia, vitamin D3 refractory rickets, hyperphosphaturia, hypercalciuria, elevated circulating 1, 25(OH)2D3 levels, and low serum parathyroid hormone (PTH) levels, leading to growth retardation, limb deformities
The definition of normocalcemic primary hyperparathyroidism is a disorder where elevated parathyroid hormone (PTH) levels are the result of autonomous hypersecretion of one or more parathyroid glands and serum
PTH controls calcium, phosphorus, and magnesium levels in the blood
primary hyperparathyroidism are asymptomatic and are detected incidentally on routine biochemical assays
Urine test
“Primary” means this disorder begins in the parathyroid glands, rather than resulting from another health problem such as kidney failure
