Which statement best describes post-thyroidectomy calcium management?

• A. Do not monitor calcium after surgery.
• B. Do not provide calcium supplementation even if hypocalcemia occurs.
• C. Monitor calcium levels and adjust supplementation; involve endocrinology as needed.
• D. Calcium management is not important post-thyroidectomy.

Answer: (C)

Post-thyroidectomy calcium management hinges on anticipating and treating hypocalcemia caused by possible injury or devascularization of the parathyroid glands. The key idea is to actively monitor calcium levels after surgery and tailor supplementation based on the results, with involvement of an endocrinologist for guidance if calcium remains low or fluctuates. In the immediate post-op period, check serum calcium (and consider ionized calcium and magnesium), watch for symptoms such as tingling, muscle cramps, or tetany, and adjust calcium and often calcitriol (active vitamin D) dosing to maintain normal calcium levels. As parathyroid function may recover over time, dosing can be reassessed and tapered as appropriate. This approach—continuous monitoring, dose adjustment, and expert input as needed—best prevents complications from hypocalcemia. The other options imply neglecting monitoring or treatment, which can lead to dangerous, symptomatic lows, and do not reflect the need for proactive, individualized management.
