Definition/Description
[edit | edit source]
Hyperparathyroidism is a disorder caused by oversecretion of parathyroid hormone (PTH) by one or more of the four parathyroid glands.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title This disorder can disrupt calcium, phosphate, and bone metabolism. Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive titleThe parathyroid glands are located in the neck on the posterior surface of each lobe of the thyroid gland. Cite error: Invalid <ref>

tag; name cannot be a simple integer. Use a descriptive title Each of the four parathyroid glands is about the size of a grain of rice.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title As part of the endocrine system, these glands secrete parathyroid hormone (PTH), which regulates calcium and phosphorus. Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title Hyperparathyroidism is classified into three groups: primary, secondary, or tertiary.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Primary hyperparathyroidism develops when there is an imbalance between serum calcium levels and PTH secretion.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Secondary hyperparathyroidism occurs when the glands have become enlarged due to malfunction of another organ system.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title Causes of secondary hyperparathyroidism include; severe deficiency in vitamin D, severe deficiency in calcium, and chronic renal failure. Chronic renal failure is the most common cause of secondary hyperparathyroidism.[1]
Tertiary hyperparathyroidism is seen in dialysis clients who have chronic secondary hyperparathyroidism.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title Dialysis clients who suffer from chronic renal failure lack the ability to absorb and convert vitamin D into a form that can be used by the body. This decline in vitamin D decreases the amount of calcium that can be absorbed.[1]

Medications[edit | edit source]
Medications to treat hyperparathyroidism include:
Calcimimetics. Calcimimetics mimic calcium circulating in the blood and may trick the parathyroid glands into releasing less parathyroid hormone. It may be prescribed to treat primary hyperparathyroidism, particularly if surgery hasn't successfully cured the disorder or a person isn't a good candidate for surgery.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Hormone replacement therapy. Hormone replacement therapy (HRT) does not address the underlying causes of excess PTH but helps to prevent bone from demineralizing as a result of excess PTH in the blood. HRT is used for menopausal women or for individuals who are exhibiting signs of osteoporosis. Estrogen and progestin are commonly used in combination for this treatment option.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Bisphosphonates- Bisphosphonates prevents the loss of calcium from bones decreasing the risk for development of osteoporosis which is caused by hyperparathyroidism.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Calcitonin- Calcitonin is used in the treatment of osteoporosis.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title It binds to osteoclasts and inhibits their action, helping to prevent the breakdown of bone.Cite error: Invalid <ref>
tag; name cannot be a simple integer. Use a descriptive title
Diagnostic Tests/Lab Tests/Lab Values[edit | edit source]
Diagnostic tests/Labs:
- Blood tests are used to indicate how much calcium, PTH and phosphorus are in the blood. If an elevated amount of any of these is found in the blood it may be indicative of overactivity of the parathyroid glands.Cite error: Invalid
<ref>
tag; name cannot be a simple integer. Use a descriptive title
Other tests once diagnosis has been made:
- Bone mineral density test (bone densitometry). Dual energy X-ray absorptiometry, or a DXA scan, is commonly used to measure bone mineral density. This test measures how many grams of calcium and other minerals are packed into a segment of bone. Cite error: Invalid
<ref>
tag; name cannot be a simple integer. Use a descriptive title - Urine tests. A 24-hour collection of urine can be used to measure kidney function and how much calcium is expelled in urine. This test may help in determining if kidney dysfunction or parathyroid disorder is the primary cause of bone demineralization. Cite error: Invalid
<ref>
tag; name cannot be a simple integer. Use a descriptive title - Imaging tests of kidneys. Used to determine presence of kidney stones or other kidney abnormalities.Cite error: Invalid

Medical Management (current best evidence)[edit | edit source]
Treatment for primary hyperparathyroidism is surgical removal of affected parathyroid gland, management of any bone or organ damage, and use of medication to protect bones prior to surgery or when parathyroidectomy is not an option. Cite error: Invalid <ref>
