There are several types of hypoparathyroidism including surgery to the neck, congenital, autoimmune, pseudohypoparathyroidism, and familial.
Surgery to the neck
About 75% of hypoparathyroidism cases are caused by neck surgery (such as having the thyroid gland removed), during which the parathyroid glands get damaged or are inadvertently removed.
Because the incidence of temporary post-surgical hypocalcemia is fairly common, the diagnosis of chronic hypoparathyroidism is not made until a patient has had low to no parathyroid hormone detected on lab tests after six months following neck surgery.
The remaining 25% of cases of hypoparathyroidism fall into a few different categories.
The following is a brief overview of a few examples of non-surgical types of hypoparathyroidism.
