Most people have four parathyroid glands. These oval, rice-size glands produce parathyroid hormone, which helps to maintain proper balance of calcium in blood and tissues. For patients with hyperparathyroidism, one or more parathyroid glands produce more than enough parathyroid hormone, which leads to the high level of calcium in blood (hypercalcemia). Hyercalcemia may cause a variety of health problems. Surgery is the the most common treatment.
