Who’s at Risk?
Several groups are more susceptible to developing hyponatremia, including:
Older adults
Aging can affect the body’s ability to regulate sodium and water balance, making older individuals more prone to hyponatremia. With age, the kidneys may become less efficient at processing electrolytes, including sodium, increasing the risk for imbalance.
Individuals taking diuretics or antidepressants
These medications can interfere with sodium levels.
Diuretics, which are often prescribed for hypertension or fluid retention, increase urine output and can lead to the loss of sodium. Similarly, some antidepressants can affect electrolyte balance.
High-performance athletes
Marathon runners and other endurance athletes are at risk due to excessive sweating and sometimes overhydration.
Intense physical activity can lead to significant sodium loss through sweat, and drinking too much water without replacing sodium can dilute the remaining sodium in the body.
Residents of hot climates
People in warmer areas may experience increased sweat loss, leading to a higher risk of hyponatremia. In hot climates, the body sweats more to cool down, leading to significant fluid and electrolyte loss if not adequately replenished.
