Question: 1 / 400

Hyponatremia is usually related to which condition?

Dehydration

Excess total body water

Hyponatremia, which refers to a lower than normal concentration of sodium in the blood, is typically associated with an excess of total body water. When the body retains too much water relative to the amount of sodium, the dilution effect leads to decreased sodium levels. This could occur in a variety of scenarios, such as heart failure, kidney diseases, or excessive fluid intake.

While dehydration can lead to hyponatremia if the water loss exceeds sodium loss, it more commonly results in high sodium levels due to reduced overall fluid volume. Loss of electrolytes or having excess potassium might influence electrolyte balance, but these conditions do not directly characterize the primary cause of hyponatremia. Thus, excess total body water stands out as the most relevant condition related to this electrolyte imbalance.
