Effectiveness of laparoscopic Roux-en-Y gastric bypass on obese class I type 2 diabetes mellitus patients

Both obese class II and III patients and obese class I T2D patients showed significant improvement in multiple parameters after LRYGB. Obese class II and III patients had a higher complete remission rate than obese class I patients. Standardized remission criteria are needed to make outcomes form different centers comparable. Large prospective studies are needed and long-term outcomes have to be observed to better evaluate effectiveness of LRYGB on obese class I T2D patients.
