Hyponatremia available in many areas of the world. Raising the serum sodium concentration too rapidly may cause central pontine myelinolysis. Avoid correction that leads to a serum sodium rise of more than 12 mEq/L/day. Hyponatremia is the most commonly seen water–electrolyte imbalance. The disorder is more frequent in females, the elderly, and in people who are hospitalized. The incidence of hyponatremia depends largely on the patient population. A hospital incidence of 15–20% is common, while only 3–5% of people who are hospitalized have a serum sodium level (salt blood level) of less than 130 mmol/L. Hyponatremia has been reported in up
Hyponatremia saline is only recommended in those with significant symptoms and occasionally those in whom the condition was of rapid onset. 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 should generally be gradual in those in whom the low levels have been present for more than two days. Hyponatremia occurs in about 20% of those admitted to hospital and 10% of people during or after an endurance sporting event. Among those in hospital, hyponatremia
