What is Hyperparathyroidism

What is Hyperparathyroidism
Hyperparathyroidism is an increase in parathyroid hormone (PTH) levels in the blood.
 This occurs either from a disorder within the parathyroid glands (primary hyperparathyroidism) or disorder outside the parathyroid glands (secondary hyperparathyroidism) resulting in them making too much PTH.

Symptoms
Symptoms may be so mild and nonspecific that they don't seem at all related to parathyroid function, or they may be severe. The range of signs and symptoms include:

Fragile bones that easily fracture (osteoporosis)
Kidney stones
Excessive urination
Abdominal pain
Tiring easily or weakness
Depression or forgetfulness
Bone and joint pain
Frequent complaints of illness with no apparent cause
Nausea, vomiting or loss of appetite
