Hyponatremia can occur when there is a decreased ability of the kidneys to excrete water. Hyponatremia can also be caused from persistent release of antidiuretic hormone, sodium losses via paracentesis, excessive diuretic use or overly aggressive sodium restriction . If hyponatremia is caused by excessive fluid, fluid intake must be restricted; typical free water restrictions are from 1,000-1,500 ml per day. If hyponatremia is due to an excessive loss of sodium, sodium must be supplemented cautiously.
