  • -located on the thyroid gland. -Most people have four pea-sized parathyroid glands ~relatively small gland compared to the other glands and organs around it.
  • -PTH is a hypercalcemic hormone because it acts to increase blood levels of Calcium-Decreasing blood Ca levels prompt the release of PTH, which causes blood Ca levels to rise, ending the stimulus for PTH release
  • -surgery can be done in 13 minutes or less
  • -Not enough Ca; too much Phosphorous-cataracts: cloudy lens-muscle spasms = tetany-Hypoparaythroidism can be acquired from accidental removal or damage to parathyroid gland during surgery (i.e. to remove throat cancer) (less common now)-usually a chronic disorder
  • -extremely rare with about one case in every 1,000 patients with parathyroid disease-symptoms are similar to those of hyperparathyroidism because both involve too much PTH-All patients with hyperparathyroidism have elevated parathyroid hormone in their blood, those with benign disease tend to have levels in the "hundreds" where as those with parathyroid cancer tend to have values in the "thousands." -The parathyroid gland and the half of the thyroid on the same side as the cancer is typically removed.
