What is the medical condition characterized by low sodium concentration in athletes?

Hyponatremia is the medical condition characterized by low sodium concentration in the blood. This can occur in athletes, particularly during intense or prolonged physical activity, when excessive sweating leads to a significant loss of sodium and an imbalance in electrolyte levels. When athletes consume large amounts of water without adequately replacing sodium, it can dilute the sodium concentration in their bodies, resulting in hyponatremia.

This condition can lead to various symptoms, such as headaches, nausea, confusion, and in severe cases, seizures or coma. Understanding the importance of electrolyte balance, especially sodium, is crucial for athletes to maintain optimal performance and health. This highlights the need for proper hydration strategies that include not only fluid intake but also adequate electrolyte replenishment during and after physical activity.
