Occurs when insufficient parathyroid hormone (PTH) is produced to mainatin extracellular levels of calcium within the normal range.

Aetiology:
Congenital (eg parathyroid dysplasia; failure of gland to develop); iatrogenic (eg surgery); destruction (eg sarcoidosis, radiation, autoimmune, tumour); suppression (eg hypomagnesaemia, drugs); impaired action of hormone (eg pseudohypoparathyroidism)

Clinical features:
Mostly due to increased neuromuscular irritability.
Parathesias, muscle cramps, altered mental status, psychosis, pain, difficulty walking, hyperreflexia, tetany, seizures

Involvement of foot:
Dry skin

Management:
Aim is to restore calcium and phosphorous levels  use calcium and vitamin D supplements
