Dear Sir,
We would like to share ideas on ‘Impact of bariatric surgery on type 2 diabetes in morbidly obese patients and its correlation with pre-operative prediction scores.[1] ‘ Gupta et al. concluded that ‘Besides leading to excess body mass index loss of 61.2%, bariatric surgery also resulted in diabetes remission in … predictive accuracy for T2DM remission.[1] ‘ We agree that there might be a remission of diabetes. However, an exact cause of remission is still unclear and might or might not relate to surgery. In the present report, both blood sugar and HbA1C are used for diagnose diabetes but only HbA1C was used for diagnose of remission. In a case with diabetes, there might be diabetic management before surgery and during hospitalisation. Patients might receive drugs and have nutritional modification. In a recent report, post-operative glycaemic control was associated with relapse of diabetes after remission.[2] In addition, duration of diabetes illness was also associated with relapse.[2] These factors might result in an improved HbA1C. We should recognise the mentioned confounding factors that might play additional roles to remission of diabetes.
