In a client with hypoparathyroidism, which dietary pattern is most appropriate?

• A. High in phosphorus and low in calcium
• B. Low in phosphorus and low in calcium
• C. Low in phosphorus and high in calcium
• D. High in phosphorus and high in calcium

Answer: (C)

Hypoparathyroidism causes low calcium and high phosphate because parathyroid hormone normally raises calcium and promotes phosphate excretion. With deficient PTH, the goal of the diet is to boost calcium while reducing phosphate, helping calcium stay available rather than becoming bound as phosphate. A pattern that is high in calcium and low in phosphorus best supports this balance, providing calcium to raise serum levels and limiting phosphate load to prevent further calcium binding. In contrast, high phosphate intake worsens the phosphate excess, and low calcium without addressing phosphate won’t correct the calcium deficit; patterns with both high phosphate and high calcium don’t reduce the phosphate burden, and patterns low in calcium don’t raise calcium effectively. Practically, this means choosing calcium-rich foods but keeping phosphate-containing foods (like those with additives and excessive dairy or processed meats) in check to improve calcium availability.
