postoperative hypoparathyroidism
Decreased parathyroid hormone production following surgery, causing hypocalcemia. May be temporary or permanent.
Full Definition
Postoperative hypoparathyroidism is a common complication following thyroid or parathyroid surgery, resulting from inadvertent removal, devascularization, or trauma to the parathyroid glands. This condition leads to decreased parathyroid hormone (PTH) production and subsequent hypocalcemia. Symptoms can range from mild paresthesias to severe tetany and cardiac arrhythmias. The condition may be temporary (resolving within 6 months) due to reversible gland dysfunction, or permanent if glands are removed or irreversibly damaged. Management includes calcium and vitamin D supplementation, with the goal of preventing symptomatic hypocalcemia while allowing potential recovery of gland function.
Usage
Usage note: Specify whether temporary or permanent when duration is established.
