Clinical Presentation of Hypoparathyroidism.

Abstract

Parathyroid hormone (PTH) is one of the major hormones that regulates serum calcium. Hypoparathyroidism occurs when PTH secretion is insufficient. The main symptoms of hypoparathyroidism are the result of low blood calcium levels, hypocalcemia, which interferes with normal muscle contraction and nerve conduction. As a result, people with hypoparathyroidism can experience paresthesia, an unpleasant tingling sensation around the mouth and in the hands and feet, as well as muscle cramps and severe spasms known as tetany that affect the hands and feet. Many also report a number of other subjective symptoms. Hypocalcemia can be the cause of medical emergencies, for example seizures, severe irregularities in the normal heart beat, as well as laryngospasm, stridor, bronchospasm, and wheezing.
