Video Summary
Hyperparathyroidism is a condition in which the parathyroid glands produce too much parathyroid hormone (PTH), which regulates calcium levels in the blood. Hyperparathyroidism can be primary, secondary, or even tertiary.
Primary hyperparathyroidism usually results from PTH secretion by a parathyroid adenoma. It is characterized by excess PTH that leads to high blood calcium levels (hypercalcemia), bone mass loss, kidney stones, and other health problems, such as psychiatric issues.
Secondary hyperparathyroidism develops when there are conditions like chronic kidney disease, which can lead to low calcium, high phosphate, and low vitamin D levels. It is mainly characterized by osteodystrophy, in which there is bone weakening associated with bone pain and deformation.
Finally, there is tertiary hyperparathyroidism, which occurs because of chronic secondary hyperparathyroidism from kidney disease. This leads to hypercalcemia and phosphate imbalances.
