- Primary—a benign tumor of the parathyroid gland that makes too much PTH (most common form)
- Secondary—occurs in patients with long-standing kidney failure or a vitamin D deficient state
- Tertiary—also occurs in patients with very long-standing kidney failure and dialysis

- Noncancerous tumor in the parathyroid gland (most common cause)
- Parathyroid cancer (very rare)
- Familial hyperparathyroidism
- Multiple endocrine neoplasia (MEN)
- Vitamin D deficiency (due to inadequate dietary intake, lack of sunlight exposure, or malabsorption condition like celiac disease)
- Kidney failure or other medical problems that make the body resistant to the action of the parathyroid hormone
- Enlargement of the parathyroid glands—common cause
- Age: older than 50 years
- Multiple endocrine neoplasia
- Having specific genetic factors that increase your risk
- Radiation therapy to head or neck during childhood
- Blood tests—to measure calcium, phosphorus, magnesium, alkaline phosphatase, vitamin D, and PTH, kidney and liver function tests
- Urine test—a 24-hour urine collection to measure calcium excretion and kidney function (very important test)
- Neck ultrasound —a test that uses sound waves, not radiation, to detect a large parathyroid tumor (adenoma)
- Technetium 99m sestamibi scan—a nuclear medicine test that uses safe nuclear molecules to make pictures of the parathyroid glands to help locate a single parathyroid adenoma in primary hyperparathyroidism
- If a growth is causing the problems, surgery may be done to remove the growth. This can often result in a growth.
Hyperaparthyroidism due to a vitamin D deficiency may be treated with:
- Vitamin D ergocalciferol or cholecalciferol —for treating secondary hyperparathyroidism due to vitamin D deficiency.
- Calcitriol (the most active vitamin D metabolite)—helps to reduce PTH production in secondary hyperparathyroidism in chronic kidney failure
- Cinacalcet —helps to lower PTH blood levels for secondary and tertiary hyperparathyroidism in chronic kidney disease or parathyroid cancer
- Treating underlying causes
- Medication to manage possible side effects
