Introduction
In addition to discontinuing water intake, intravenous fluid administration must also be stopped in cases of acute water intoxication. In severe cases, sodium chloride may be administered to correct hyponatremia, rapidly increasing the osmolarity of the extracellular fluid and thereby drawing intracellular fluid out of cells to alleviate symptoms of acute water intoxication. Furthermore, patients with acute water intoxication require strict restriction of fluid intake. If fluid intake is substantial, diuretic therapy may be appropriately administered.

Water intoxication occurs when impaired renal urine excretion leads to excessive water retention in the body, resulting in increased cellular water content and subsequent cellular dysfunction. Acute water intoxication has a sudden onset and severe symptoms; thus, how can it be rapidly alleviated?

How to Rapidly Alleviate Acute Water Intoxication

In addition to immediately ceasing oral water intake, intravenous fluid administration must also be discontinued. In severe cases, sodium chloride supplementation is required to correct hyponatremia, rapidly increasing extracellular fluid osmolarity. This promotes the movement of intracellular fluid out of cells, thereby alleviating acute water intoxication symptoms. Furthermore, patients with acute water intoxication require strict restriction of total fluid intake. If fluid overload persists, diuretic therapy may be appropriately administered. Commonly used diuretics include nicotinic acid and furosemide. Hemofiltration may be performed, and cardiac protective agents such as nitroglycerin or sodium nitroprusside may also be employed.

Upon entering the body, acute water intoxication causes a decline in plasma osmolarity, leading to decreased serum sodium concentration—commonly known as hyponatremia. The primary danger of hyponatremia lies in cellular edema and swelling. When affecting various tissues and organs, the most serious manifestations include cerebral edema and brain swelling; pulmonary edema may also occur, and the burden on the heart and vasculature increases significantly.

Water intoxication is most commonly encountered in its acute form. During acute water intoxication, cerebral edema develops, leading to symptoms of increased intracranial pressure. Prompt treatment is essential. We hope this response proves helpful to you.
