Final answer:
Parathyroid adenomas are associated with hypercalcemia due to overproduction of parathyroid hormone, leading to increased calcium levels and potential bone and kidney issues. They are not directly linked to hypertension, bloating, acne, or headaches.
Step-by-step explanation:
Parathyroid adenomas are often associated with hypercalcemia. This is because adenomas can cause hyperparathyroidism, where there is an overproduction of parathyroid hormone (PTH), leading to an increase in calcium reabsorption from the bones into the bloodstream. Hyperparathyroidism is known to result in a variety of symptoms such as high serum calcium levels, low serum phosphate, bone destruction, and potentially kidney stones. It is important to note that parathyroid tumors are a common cause of hyperparathyroidism. Unlike hypercalcemia, conditions such as hypertension, bloating, acne, and headaches have not been directly associated with parathyroid adenomas as they are often associated with other medical issues.
