What is a common sign of hypoparathyroidism?

Tetany or convulsions are characteristic signs of hypoparathyroidism due to the resultant low levels of parathyroid hormone (PTH), which leads to decreased calcium levels in the blood (hypocalcemia). PTH plays a crucial role in maintaining calcium homeostasis; when its levels drop, calcium levels also fall, leading to increased neuromuscular excitability. This can manifest as tetany, which includes symptoms such as muscle cramps, spasms, and convulsions.

Patients may also experience symptoms like tingling sensations in the fingertips and around the mouth, known as paresthesia, along with other signs indicative of low calcium levels. Addressing the underlying hypoparathyroidism and the associated hypocalcemia is essential for alleviating these symptoms and preventing serious complications.
