Which of these occurs with exercise-associated hyponatremia (EAH)?

Exercise-associated hyponatremia (EAH) is a condition that occurs when there is an abnormally low concentration of sodium in the blood, typically resulting from prolonged physical activity, especially in hot environments. This condition can lead to fluid retention, causing cells to swell, which is particularly concerning for brain cells.

Increased intracranial pressure occurs as the brain cells swell due to the influx of fluids, resulting in potential consequences like headache, confusion, seizures, or even coma. The increased volume of fluid in the cranial cavity can lead to life-threatening complications, especially if not addressed quickly.

Understanding the physiological changes during exercise is crucial for recognizing EAH and its associated risks. While increased body temperature and decreased body temperature can both occur during various exercise scenarios, they are not directly related to EAH. Additionally, decreased intracranial pressure would not be a symptom of EAH, as swelling from fluid shifts underlies the increased pressure scenario. Therefore, recognizing the significance of increased intracranial pressure is essential for EMTs and medical professionals when assessing and managing patients with exercise-related conditions.
