Parathyroid Disorders

• Excessive secretion of PTH leads to excessive bone resorption

  hyperparathyroidism
• Hyperparathyroidism leads to increased blood levels of calcium resulting in

  decreased bone density, leading to increased fractures, reduced responsiveness of nervous system, increased calcium deposits in tissues and organs
• Insufficient production or secretion of PTH

  hypoparathyroidism - leads to low blood levels of calcium, causing muscle twitching, cramping, convulsions, or paralysis
