Patients with diabetes must be monitored for hyperglycemia due to the risk of macrocellular and microcellular complications. High blood sugar levels force the kidneys to work harder to filter blood, which results in renal leakage. The objective of this study was to establish a relationship between glycemic control, management adherence, and hemoglobin level in patients with type 2 diabetes. This study employed a correlational design with a cross-sectional approach and a sample size of 72 respondents selected using purposive technique. Compliance with diabetes mellitus, which includes diet compliance, exercise compliance, medication compliance, and blood sugar monitoring compliance, is strongly correlated with glycemic control levels. Completely contrary, there was no link between hemoglobin levels and adherence to treatment. Microcellular processes of renal function are linked to the interaction between glycemic control and hemoglobin levels.
