ANATOMY

Detailed explanation-1: -In primary hyperparathyroidism, an enlargement of one or more of the parathyroid glands causes overproduction of parathyroid hormone. This causes high calcium levels in the blood, which can cause a variety of health problems. Surgery is the most common treatment for primary hyperparathyroidism.

Detailed explanation-2: -When you have high levels of parathyroid hormone (PTH) in your blood, it causes you to have high levels of calcium in your blood (hypercalcemia) and low levels of phosphorous in your blood (hypophosphatemia), which cause certain symptoms and health conditions.

Detailed explanation-3: -Parathyroid hormone is directly involved in the bones, kidneys, and small intestine. In the bones, PTH stimulates the release of calcium in an indirect process through osteoclasts which ultimately leads to the resorption of the bones.

Detailed explanation-4: -Parathyroid hormone (PTH) is a hormone that your parathyroid glands make and release to control the level of calcium in your blood by increasing it.
