What is hyponatremia and what is its danger?

The term “hyponatremia” itself can be translated as “sodium deficiency”, which is essentially a salt deficiency. Sodium is the key electrolyte found in the intercellular space: it accounts for more than 60% of the total amount of electrolytes. It is needed to transmit impulses from muscle contraction and enable motor activity.

The normal concentration of sodium in human plasma is 135-145 mmol/L. With a slight decrease in these indicators, doctors diagnose a mild form of hyponatremia. If the plasma sodium concentration falls below 125 mmol/L, the symptoms become more pronounced and may require medical attention.
