2 de ene. de 2022 · Hyponatremia is defined as a serum [Na +] <135 mmol/L. In the majority of cases, hyponatremia is a consequence of water disturbances that result in a relative excess of body water compared with the body sodium content.
25 de oct. de 2023 · Hyponatremia represents a relative excess of water in relation to sodium. It can be induced by a marked increase in water intake (primary polydipsia) and/or by impaired water excretion due, for example, to advanced kidney failure or persistent release of antidiuretic hormone (ADH). (See "Causes of hypotonic hyponatremia in adults" .)
Red Flags: Nausea and vomiting. Irritability. Headache. Decreased conscious state. Seizures. Management. Investigations (recommended if Na <130 mmol/L)
Hyponatraemia usually occurs due to excess water intake or impaired free water excretion. Acute hyponatraemia can result in cerebral oedema. Severity: Mild (125-135 mmol/L): most children are asymptomatic. Moderate (120-125 mmol/L): children may have non-specific symptoms such as nausea and malaise.
