Unmasking Diabetes in Dialysis With Continuous Glucose Monitoring

This study will evaluate whether Continuous Glucose Monitoring (CGM) can identify previously unrecognized diabetes and clinically significant hyperglycemia in adults with end-stage kidney disease (ESKD) receiving hemodialysis who have no known history of diabetes. Participants will wear a CGM sensor for up to 15 days and undergo standard diabetes assessments, including fasting plasma glucose and hemoglobin. The primary objectives are to: * Determine the prevalence of previously undiagnosed diabetes among dialysis patients using OGTT criteria. * Compare CGM glucose patterns between participants with and without diabetes as determined by OGTT results.
