It is the most common cause of blindness, amputation and kidney failure in western adults, besides increase the risk of coronary disease and stroke with high mortality of patients. The association of type 2 diabetes with obesity is really significant. Obese diabetic patients had a better glucose control after bariatric surgery even prior to weight loss. METHODS: A systematic review in Pubmed, Bireme and Scielo research sites was made, using "Diabetes Mellitus", "Bariatric Surgery" and "Obesity" keywords. Were selected the studies related to surgical techniques in the treatment of obesity and type 2 diabetes. The papers presented at the 1st and 2nd World Congress of Interventional Therapies for Type 2 Diabetes was also included.

However, the procedures and techniques used must be more investigated in randomized controlled trials comparing the clinical and surgical treatments, in animals and in humans.
