General Discussion
Hypoparathyroidism is a condition characterized by insufficient production of parathyroid hormones by the parathyroid glands, the small, oval glands located near the thyroid gland in the neck. Parathyroid hormones (along with vitamin D and the hormone calcitonin, which is produced by the thyroid gland) play a role in regulating levels of calcium in the blood. Due to deficiency of parathyroid hormones, affected individuals exhibit abnormally low levels of calcium in the blood (hypocalcemia). Symptoms and findings associated with Hypoparathyroidism may include weakness, muscle cramps, excessive nervousness, headaches, and/or increased excitability (hyperexcitability) of nerves resulting in uncontrollable twitching and cramping spasms of certain muscles such as those of the hands, feet, arms, and/or face (tetany). Hypoparathyroidism may result from absence of the parathyroid glands at birth, occur due to or in association with a number of different underlying disorders, or result from removal of or damage to the parathyroid glands. In rare cases, Hypoparathyroidism may be inherited as an autosomal recessive genetic trait.
