Which symptom is associated with vitamin D toxicity?

• A. Hypocalcemia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hypomagnesemia

Answer: (B)

Vitamin D toxicity raises serum calcium by boosting intestinal calcium absorption and increasing bone resorption. The result is hypercalcemia, which produces symptoms like nausea, vomiting, fatigue, weakness, polyuria, and polydipsia, and can lead to kidney stone formation or tissue calcifications. Because the question links toxicity to a calcium-related problem, the best answer is hypercalcemia. Hypocalcemia, hypokalemia, and hypomagnesemia do not align with the effects of excess vitamin D.
