  New York Thyroid Center: Hyperparathyroidism
Most cases (85%) of hyperparathyroidism are the result of a single parathyroid gland malfunctioning and developing into a benign tumor, known as an adenoma.
Oftentimes a person with hyperparathyroidism has no symptoms, or they attribute their symptoms to other causes, and they first learn about the disease from blood tests taken during a routine visit to the doctor.
Hyperparathyroidism is diagnosed by simple blood tests which check the blood level of calcium as well as a blood level of parathyroid hormone.

  Hyperparathyroidism   (Site not responding. Last check: 2007-10-29)
Primary hyperparathyroidism is caused by a defect in the parathyroid gland itself causing primary hypersecretion.
Secondary hyperparathyroidism is hypersecretion of the parathyroids in response to a defect elsewhere in the body causing chronic calcium depletion.
The symptoms of hyperparathyroidism relate to the role calcium plays in electrical conduction in tissues such as the central nervous system, the heart, skeletal and smooth muscle, and to deposition of insoluble calcium salts in tissues such as the kidney.

  Hyperparathyroidism - Wikipedia, the free encyclopedia
Primary hyperparathyroidism results from a dysfunction in the parathyroid glands themselves, with oversecretion of PTH.
Secondary hyperparathyroidism is due to resistance to the actions of PTH, usually due to chronic renal failure.
Once an elevated PTH has been confirmed, goal of diagnosis is to determine whether the hyperparathyroidism is primary or secondary in origin by obtaining a serum calcium level.

Primary hyperparathyroidism occurs as a malfunction of one of the glands, usually as a result of a benign tumor, called adenoma.
Secondary hyperparathyroidism occurs as the result of a metabolic abnormality outside the parathyroid glands, which causes a resistance to the function of the parathyroid hormones.
Hyperparathyroidism cases will usually be referred to an endocrinologist, a physician specializing in hormonal problems, or a nephrologist, who specializes in kidney and mineral disorders.

Hyperparathyroidism inflicts damage to the body because it causes an abnormally high level of calcium in the blood, which slowly destroys the tissues by accelerating the calcification process.
Hyperparathyroidism is relatively easy to detect because the parathyroid glands will be making an inappropriately large amount of PTH in the presence of elevated serum calcium.

Hyperparathyroidism means that the parathyroid glands are producing an excess of a hormone called parathyroid hormone, which in turn causes elevations in the levels of calcium circulating in the bloodstream.
More often than not, today the discovery of hyperparathyroidism is associated with a routine blood test that finds an elevation in the blood calcium level.
The best treatment for this disease is surgery to remove the gland(s) which are enlarged and responsible for the elevations in calcium in the blood.

Secondary hyperparathyroidism is more common and occurs most frequently in kittens and puppies fed an all-meat or organ diet (such as all liver) or a diet with an imbalance of calcium and phosphorous.
In secondary hyperparathyroidism, because the calcium intake is low, the parathyroid gland produces more parathyroid hormone, and calcium is removed from the bones.
