Overview

The Cleveland Clinic Parathyroid Clinic addresses issues related to the parathyroid including the investigation, diagnosis, clinical and surgical management of parathyroid disease including hyperparathyroidism, hypercalcemia, vitamin D deficiency, hypoparathyroidism, and more.

What is Hyperparathyroidism?

Hyperparathyroidism is a condition in which one or more of the parathyroid glands become overactive and secrete too much parathyroid hormone (PTH). Most of the time this causes the levels of calcium in the blood to rise, a condition known as hypercalcemia.

What are the symptoms of Hyperparathyroidism?

The symptoms of hyperparathyroidism include:

  • Joint pain
  • Muscle weakness
  • Fatigue
  • Depression
  • Trouble concentrating
  • Loss of appetite
  • Nausea and vomiting
  • Confusion
  • Increased thirst and need to urinate

Other problems associated with a severe case of hyperparathyroidism include:

  • Reduced kidney function, which affects the kidney's ability to filter blood
  • Kidney stones
  • Thinning bones (osteoporosis)

What are the causes of hyperparathyroidism?

There are three main types of hyperparathyroidism. The causes of each differs learn more below:

  • In primary hyperparathyroidism one or more of the parathyroid glands cause overproduction of the hormone leading to hypercalcemia. Treatment depends of the severity of the symptoms. Surgery is the most common treatment but sometimes mild hypercalcemia can be followed medically.
  • In secondary hyperparathyroidism the parathyroid glands are overactive in an attempt to keep the calcium levels normal. This may be seen when Vitamin D levels are low, kidneys are not working well, or the intestines are not absorbing enough calcium.

Hyperparathyroid Testing

  • Parathyroid Hormone Test (PTH) – A procedure in which a blood sample is checked to measure the amount of parathyroid hormone released into the blood by the parathyroid glands.
  • Calcium - A procedure in which a blood sample is checked to measure the amount of Calcium present.
  • Phosphorous - A procedure in which a blood sample is checked to measure the amount of Phosphorous present.
  • Vitamin D - A procedure in which a blood sample is checked to measure the amount of Calcium present.
  • Dual-Energy X-ray Absorptiometry Scan (DEXA Scan) - is a technique of measuring bone mineral density to assess for osteopenia and osteoporosis.
  • Urine Test – A procedure in which a urine sample is checked to measure the amount of Calcium and phosphorous present.

If you think that you may suffer from hyperparathyroidism, please schedule an appointment with one of our specialists today. The Parathyroid Clinic also works directly with the Endocrine Surgery department to help expedite any surgical needs.
