In planning nutrition for a client with hypoparathyroidism, which diet would be appropriate?

• A. Low in vitamins A, D, E, and K
• B. Low in water and insoluble fiber
• C. High in calcium and low phosphorus
• D. High in sodium with no fluid restriction

Answer: (C)

In hypoparathyroidism, parathyroid hormone is deficient, which lowers calcium levels and allows phosphorus to rise. A diet high in calcium and low in phosphorus directly addresses this imbalance by supplying more calcium for absorption while reducing phosphate intake that would otherwise bind calcium and worsen hypocalcemia. Adequate calcium helps raise serum calcium, and limiting phosphorus prevents further disruption of calcium balance. While vitamin D status is important for calcium absorption, the overall dietary pattern that best fits the condition is emphasis on calcium-rich foods with reduced phosphorus. The other patterns don’t target this calcium–phosphate balance and could worsen hypocalcemia or offer no real benefit.
