What is an appropriate treatment option for hypercalcemia?

In the management of hypercalcemia, calcitonin is an effective treatment option because it directly lowers serum calcium levels. Calcitonin is a hormone produced by the parafollicular cells of the thyroid gland, and it works by inhibiting osteoclast activity in bones, which reduces bone resorption of calcium. Additionally, it promotes renal excretion of calcium, further aiding in lowering calcium levels in the blood.

Choosing calcitonin is particularly appropriate in cases of acute hypercalcemia, such as in the setting of malignancy or certain endocrine disorders, where rapid intervention is necessary. Its prompt action can help alleviate symptoms associated with hypercalcemia, such as nausea, vomiting, and confusion.

Other treatments are less suitable for immediate management of hypercalcemia. For example, intravenous calcium gluconate is used to treat hypocalcemia or to stabilize cardiac membranes in cases of hyperkalemia, rather than to lower calcium levels. Oral vitamin D supplementation would actually increase calcium levels and is utilized for conditions like osteomalacia or rickets, making it inappropriate for hypercalcemia. Magnesium supplements do not directly address calcium levels and are not indicated for the treatment of hypercalcemia. Thus, calcitonin is the most appropriate choice in managing
