Severe hyponatremia is associated with neurological impairment and mortality. Furthermore, severe hyponatremia can be the first presentation of several diseases. Therefore, an appropriate investigation for the underlying causes of hyponatremia apart from the proper correction of sodium levels, might lead to a diagnosis of occult diseases.

Anorexia nervosa (AN) is an eating disorder characterized by restriction of energy intake leading to a significantly low body weight, and intense fear of gaining weight. Severe electrolyte changes such as hypokalemia and hypophosphatemia; and alterations in water metabolism such as hyponatremia and edema, can occur in patients with AN. Hypokalemia and chronic volume depletion may lead to acute kidney injury (AKI) and chronic kidney disease (CKD).

Pseudohypoaldosteronism (PHA) is a rare disorder that, if not promptly recognized and treated, can lead to life-threatening hyperkalemia resulting in cardiac arrest and death. Systemic PHA is caused by variants that deactivate the epithelial sodium channel (ENaC) subunits. Management is challenging due to high-dose oral replacement therapy, and patients with systemic PHA require lifelong treatment.

Background: Birth asphyxia is a major cause of neonatal mortality and neurological morbidity. This study was aimed to determine biochemical (sodium, potassium, and calcium) abnormalities and their correlation across different severities of perinatal asphyxia in term neonates.

Methods: This observational analytical study was conducted in term neonates with perinatal asphyxia admitted at the neonatal intensive care unit of a tertiary care centre for a period of 18 months.
