reatment is based on the underlying cause.[1] Correcting hyponatremia too quickly can lead to complications.[6] Rapid partial correction with 3% normal saline is only recommended in those with significant symptoms and occasionally those in whom the condition was of rapid onset.[1][7] Low volume hyponatremia is typically treated with intravenous normal saline. SIADH is typically treated with fluid restriction while high volume hyponatremia is typically treated with both fluid restriction and a diet low in salt. Correction, in those in whom the low levels have been present for more than two days should generally be gradual.[1]
Hyponatremia is one of the most commonly seen water–electrolyte imbalances.[7][8] It occurs in about 20% of those admitted to hospital and 10% of people during or after an endurance sporting event.[4][6] Among those in hospital hyponatremia is associated with an increased risk of death.[6] The economic costs of hyponatremia are estimated at $2.6 billion in the United States
