Medically reviewed by Min Clinic Staff | Updated: January 2026
Parathormone: A hormone that is made by the parathyroid glands and is critical to maintaining calcium and phosphorus balance. Deficiency of parathormone results in abnormally low calcium in the blood (hypocalcemia). Excessive parathormone leads to elevated calcium levels in the blood and calcium deposition in cartilage. Also known as parathyroid hormone and parathyrin.
