Background: To assess the correlation between obesity and glycated haemoglobin in type 2 diabetic patients. Materials & methods: 50 patients were enrolled. The categorisation of patients was done based on BMI. Blood samples were obtained and sent to the laboratory where HbA1c values were assessed. Further evaluation of the correlation between obesity and glycated haemoglobin in type 2 diabetic patients was done. Results: Mean HbA1c among diabetic subjects with normal BMI, overweight and obese status was 7.2%, 8.9% and 10.1% respectively. Significant results were obtained while correlating obesity and glycated haemoglobin in type 2 diabetic patients. Conclusion: There exists a significant correlation between obesity and glycated haemoglobin in type 2 diabetic patients.
