What are the symptoms of hyperparathyroidism?

The symptoms of hyperparathyroidism are primarily related to the overproduction of parathyroid hormone, which leads to elevated levels of calcium in the blood (hypercalcemia). This condition can result in a range of clinical manifestations.

Excessive thirst and frequent urination are common due to the kidneys' increased calcium handling and the body's attempt to excrete the excess calcium, leading to polyuria. Bone pain is also a hallmark symptom because the elevated parathyroid hormone levels cause the bones to release calcium, leading to osteitis fibrosa cystica and other bone-related changes.

Thus, the combination of excessive thirst, frequent urination, and bone pain aligns well with the physiological effects of hyperparathyroidism, making it the correct choice. Other options mentioned, while relating to different conditions, do not encompass the primary symptoms associated specifically with hyperparathyroidism.
