Question

Causes of ________are VITAMIN D METABOLIC DISORDERS, abnormal PTH function, primary hyperparathyroidism, Lithium, malignancy, disorders related to high bone turnover rates (hyperthyroidism, prolonged immobilization, thiazide use, vit A intoxication, Pagets dz of bone, multiple myeloma), renal failure

Answer 1

Hyperparathyroidism is a disorder characterized by overproduction of parathyroid hormone (PTH) which leads to excessive calcium reabsorption from bone. The causes include abnormal PTH function, primary hyperparathyroidism, vitamin D metabolic disorders, and other factors like renal failure and certain medications.

Step-by-step explanation:

Hyperparathyroidism is a disorder characterized by overproduction of parathyroid hormone (PTH) which leads to excessive calcium reabsorption from bone. This can result in decreased bone density, spontaneous fractures, and deformities. The causes of hyperparathyroidism include abnormal PTH function, primary hyperparathyroidism, vitamin D metabolic disorders, lithium use, malignancy, and disorders related to high bone turnover rates. Other factors like renal failure and certain medications can also contribute to the development of hyperparathyroidism.
