What is the primary treatment for managing euvolemic hyponatremia?

Managing euvolemic hyponatremia focuses on correcting the low sodium levels while maintaining fluid balance in the body. In cases of euvolemic hyponatremia, the body's overall volume status is normal, but sodium concentration is low due to excess water relative to sodium.

The primary treatment involves fluid restriction to help increase the sodium concentration in the blood. By limiting fluid intake, you reduce the diluting effect of excess water in the body, allowing the kidneys to excrete the excess water. This approach gradually corrects the sodium levels without causing rapid fluctuations, which can lead to serious complications.

While other treatments may be applicable in different contexts or types of hyponatremia, fluid restriction is central to managing euvolemic hyponatremia specifically. Sodium infusion, fluid replacement, and diuretic therapy are not effective for this condition as they may not address the underlying water imbalance and could potentially worsen the sodium levels or cause adverse effects.
