Abstract
Introduction: Sodium is the major extracellular cation, playing important role in maintaining homeostasis. Normal level of serum sodium is between 136-145 mmol/L. Hyponatremia (<136mmol/L) can present with nausea, vomiting, confusion, lethargy, disorientation.Severe hyponatremia (<125mmol/L) can present with seizures, coma or death.
Methods: Our study was a cross sectional, retrospective study including 100 subjects of hyponatremia.
Results: In our study, we analyzed the age-wise distribution, severity and various causes of hyponatremia in each grade of hyponatremia based on severity.
Conclusion: Drug-induced hyponatremia is a more prevalent and a preventable cause and can be avoided by proper monitoring of patients.
Keywords: Hyponatremia, homeostasis, risk factors
