We studied the article by Fonseca et al. [1] and we commend the authors on their findings. Obesity is a key factor contributing to the development of type 2 diabetes mellitus. Weight loss is associated with improvement of type 2 diabetes. Bariatric surgery is the most useful method for the treatment of obesity and type 2 diabetes [2]. Improvement of type 2 diabetes can be observed even before significant weight loss after bariatric surgery [2].

Fonseca et al. [1] showed that the over-expression of GHRL (ghrelin and obestatin prepropeptide) gene occurs in the excluded stomach, after bariatric surgery, but does not have a correlation to T2DM remission [1]. Expression of many genes and molecular pathways changes after bariatric surgery [3, 4]. In this letter, we mentioned the changes of other gene expressions (in addition to GHRL) in obese subjects with type 2 diabetes after bariatric surgery.
