In a patient with hypercalciuria, which statement about sports drinks and urinary calcium is true?

• A. They cause hypernatremia
• B. They will not affect urinary calcium
• C. They increase calcium excretion
• D. They cause a decrease in urinary calcium

Answer: (B)

In hypercalciuria, urinary calcium is influenced by how much sodium you take in. The kidneys reabsorb sodium and calcium in a linked way; when more sodium is filtered, more calcium is excreted in the urine. Sports drinks often contain sodium, so consuming them can raise calcium loss in urine. That’s why the statement that sports drinks have no effect on urinary calcium isn’t accurate for someone with hypercalciuria. For management, it’s helpful to focus on hydration with lower-sodium options and to consider sodium intake as a factor that can modulate calcium excretion.
