<![CDATA[Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic disease that may cause electrolyte imbalance due to prolonged hyperglycemia. This study aimed to determine the relationship between the duration of Type 2 Diabetes Mellitus and serum sodium and chloride levels among patients in the working area of Trauma Center Public Health Center, Samarinda. This analytical observational study employed a cross-sectional design. A total of 40 patients with Type 2 DM were selected using purposive sampling. Data collected included the duration of Type 2 DM and laboratory results of serum sodium (Na?) and chloride (Cl?) levels. Most respondents had normal sodium (85.0%) and chloride (85.0%) levels. Patients with a duration of Type 2 DM of ?5 years showed a higher proportion of low sodium and chloride levels than those with a duration of <5 years. Fisher’s Exact Test showed no statistically significant association between the duration of Type 2 DM and sodium levels (p = 0.661), whereas a statistically significant association was found with chloride levels (p = 0.020). In conclusion, the duration of Type 2 DM was associated with chloride levels but not with sodium levels. Routine electrolyte assessment is recommended as part of the metabolic monitoring of patients with Type 2 DM to support early detection and prevent complications.]]>
