Patient-centered outcomes after bariatric surgery for the treatment of type 2 diabetes mellitus in adolescents and adults

•Bariatric surgery in adults with BMI >35kg/m2 improves type 2 diabetes control but may result in serious adverse effects.•Bariatric surgery in adults with BMI ≤35kg/m2 and type 2 diabetes decreases HbA1c and BMI.•Laparoscopic versus open surgery results in similar rates of diabetes control but lower risk of surgical complications.•Evidence about long-term benefits and harms from bariatric surgery in adolescents is very limited.
