Treatment may be by surgical removal of the affected gland s parathyroidectomy. Further information on the symptoms for each condition can be found in the individual articles.
Too little parathyroid hormone or hypoparathyroidism , is a rare medical condition. It can result in low levels of calcium in the blood hypocalcaemia.
It is usually treated medically with oral calcium and vitamin D analogues but the availability of parathyroid hormone replacement therapy may change the approach to treatment for some patients.

Health Home Conditions and Diseases. Addition information on how parathyroid hormone and vitamin D control calcium balance can be found in the section Endocrine Control of Calcium Homeostasis. Parathyroid hormone is released in response to low extracellular concentrations of free calcium.
Changes in blood phosphate concentration can be associated with changes in parathyroid hormone secretion, but this appears to be an indirect effect and phosphate per se is not a significant regulator of this hormone. When calcium concentrations fall below the normal range, there is a steep increase in secretion of parathyroid hormone.
Low levels of the hormone are secreted even when blood calcium levels are high. The figure to the right depicts parathyroid hormone release from cells cultured in vitro in differing concentrations of calcium.
