Which of the following is a symptom of exertional hyponatremia?

Swelling of the hands and feet is a recognized symptom of exertional hyponatremia, which occurs when sodium levels in the blood become dangerously low, often due to excessive fluid intake during prolonged exercise. In this condition, the body retains excess fluid, which dilutes sodium levels and leads to swelling in various parts of the body, including the extremities. This symptom can serve as an important indicator for athletes and trainers to identify a potential imbalance and take corrective action.

In contrast, increased energy levels, improved mental clarity, and enhanced athletic performance do not typically correlate with exertional hyponatremia. In fact, individuals facing this condition may experience fatigue, cognitive confusion, and decreased athletic ability due to the physiological stress of sodium imbalance and fluid overload. Recognizing the correct symptoms, like swelling, is crucial for effective management and prevention strategies in athletic training and care.
