ntroduction- Electrolyte balance of the body is maintained by renin angiotensin aldosterone system. Some previous studies suggested that COVID-19 is associated with gastrointestinal symptoms, such as diarrhea and vomiting. This may results in electrolyte disturbances in patients. Electrolytes in body like sodium (Na), potassium (K). Chloride (Cl) plays an important physiological role in maintaining acid base and water balance of cells of the body. Aims and objectives: Our study aimed to compare some electrolyte between covid 19 and non-covid patients retrospectively. Material and Methods: This retrospective study included total 57 males and 43 females in the age group of 28 to 65 years. The results were compared with 100 age and sex matched healthy controls. Estimation of serum electrolytes was done with the collected venous blood samples using the ion selective electrode technique in an electrolyte analyzer. Analysis was done using SPSS V 25 Software. Chi-square and t-test were used to see association and difference between two variable respectively. Results: We have found that covid 19 is associated with low levels of electrolytes like Na, K, Cl. Chloride levels in both the groups was not statistically significant. But Hyponatremia and Hypokalemia were observed in cases group with high statical Signficance. Conclusion: Study found that electrolytes deterioration in these patients play a critical role in patients management. Thus a monitoring of electrolyte is essential throughout their illness to manage covid patients to improve their quality of life.
