Which outcome occurs when a patient with chronic kidney disease experiences persistently low mineral availability to bone?

💡 Explanation

Increased osteoclast activity occurs because low mineral availability stimulates parathyroid hormone (PTH) secretion, which, in turn, activates osteoclasts to resorb bone and release calcium and phosphate into the bloodstream; therefore, osteoclast activity increases, rather than PTH secretion being suppressed as the body attempts to maintain calcium homeostasis.

• Why does hyperthyroidism often cause insomnia, rather than fatigue, despite increased metabolic demand?
