It's complicated: Let's start with primary hyperparathyroidism, which is high PTH hormone levels due to a problem with the gland itself, for example from a tumor, an adenoma. Secondary hyperpth is when PTH levels go up because of a problem outside the gland, such as low calcium or low vitamin d levels. Think of it as working overtime to accomplish its function, to raise calcium levels, when it's not happening.

Hyperparathyroidism: The parathyroid glands help control calcium use and removal by the body. They do this by producing parathyroid hormone, or pth. Pth helps control calcium, phosphorus, and vitamin d levels within the blood and bone. When calcium levels are too low, the body responds by increasing production of parathyroid hormone. This increase in parathyroid hormone causes more calcium to be taken from the bone.
