A total of 50 patients aged 35-75 years From Al-Sader educational Hospital in Al-Najaf city was studied to determine the glycated hemoglobin risk factors with value creatinine and urea in serum and diabetic nephropathy. Diabetic patient were (35-45 years old) with HbA1c 7.9 % (60mmol/mol). Patient were (45–55 years old), glycated hemoglobin (HbA1c) andgt; 8.5 %. Patients between (55–65 years were glycated hemoglobin (HbA1c) andgt;10.5 %. HbA1c levels, lipid profile, level of Creatinine and urea in serum, family history, BMI, blood pressure, disease severity, and complications were determined. Most patients developed some grade of retinopathy (examined by an ophthalmologist) except those with HbA1c 6.7% (50mmol/mol). Diabetic patients aged (55–65 years old) with HbA1c 7.6% (60mmol/mol). Patients aged 56–75 years old of glycated hemoglobin (HbA1c) andgt;7% with poor glycaemia control ≥ 126mg/dL were assessed to classify diabetic retinopathy. HbA1c and GA are associated with nephropathy separately. Retinopathy and nephropathy may respond to different aspects of hyperglycemia. The GA found as a powerful indicator of microvascular complications same as HbA1c where long-term glycaemia is the risk factor.
