Primary hyperparathyroidism is when both the parathyroid hormone level and the calcium level are above normal. Two other types of hyperparathyroidism are secondary and tertiary hyperparathyroidism. Tertiary hyperparathyroidism is generally seen in patients after a kidney transplant.

Parathyroid Disorders

Parathyroid disorders lead to abnormal levels of calcium in the blood that can cause brittle bones, kidney stones, fatigue and weakness, and other symptoms.

Primary Hyperparathyroidism

Primary hyperparathyroidism is a condition that causes elevated calcium levels (hypercalcemia) in the bloodstream, due to the parathyroid glands secreting too much parathyroid hormone (PTH).
