                                Postoperative hyponatremia, defined as a serum sodium level below 135 mEq/L, is the most common electrolyte imbalance encountered in hospitalized patients following surgery. It is crucial to understand the intricate physiological changes that contribute to this condition to ensure patient safety and promote a healthier recovery process.
