Hyponatremia, type, causes, sing, symptoms and treatment/تداوی هایپوناتریمی

Hyponatremia is defined as a serum sodium (Na) concentration less than 135 mEq/L in the
blood. Hyponatremia is most common electrolyte disorder encountered in hospitalized patients.
Plasma Na plays a significant role in plasma osmolality and tonicity (serum osmolarity = 2Na +
Glucose/18 + BUN/2.8). Changes in plasma osmolality are responsible for the signs and
symptoms of hyponatremia and also the complications that happen during treatment in the
presence of high-risk factors whereas hypernatremia always denotes hypertonicity,
hyponatremia and can be associated with low, normal, or high tonicity.
