The medicine use and quality of life were solely improved in the surgical group .
Nutritional deficiencies and anemia were noted more frequently in the RYGB group .
RYGB surgery is superior to medical treatment for short- to medium-term remission of T2DM , improvement of metabolic condition , and cardiovascular risk factors .
Abstract The aim of the study is to compare Roux-en-Y gastric bypass ( RYGB ) surgery versus medical treatment for  type 2 diabetes mellitus ( T2DM ) in obese patients .Bariatric  surgery can achieve remission of T2DM in obese patients .
RYGB surgery has been performed as one of the most common surgical treatment options for obese patients with T2DM , but the efficacy of RYGB surgery comparing with medical treatment alone has not been conclusively determined .
Reduction in Weight and Cardiovascular Disease Risk Factors in Individuals With Type 2 Diabetes
OBJECTIVE —The effectiveness of intentional weight loss in reducing cardiovascular disease ( CVD ) events in type 2 diabetes is unknown . This report describes 1-year changes in CVD risk factors in a trial design ed to examine the long-term effects of an intensive lifestyle intervention on the incidence of major CVD events . RESEARCH DESIGN AND METHODS —This study consisted of a multicentered , r and omized , controlled trial of 5,145 individuals with type 2 diabetes , aged 45–74 years , with BMI > 25 kg/m2 ( > 27 kg/m2 if taking insulin ) . An intensive lifestyle intervention ( ILI ) involving group and individual meetings to achieve and maintain weight loss through decreased caloric intake and increased physical activity was compared with a diabetes support and education ( DSE ) condition . RESULTS — Participants assigned to ILI lost an average 8.6 % of their initial weight vs. 0.7 % in DSE group ( P < 0.001 ) . Mean fitness increased in ILI by 20.9 vs. 5.8 % in DSE ( P < 0.001 ) . A greater proportion of ILI participants had reductions in diabetes , hypertension , and lipid-lowering medicines . Mean A1C dropped from 7.3 to 6.6 % in ILI ( P < 0.001 ) vs. from 7.3 to 7.2 % in DSE . Systolic and diastolic pressure , triglycerides , HDL cholesterol , and urine albumin-to-creatinine ratio improved significantly more in ILI than DSE participants ( all P < 0.01 ) . CONCLUSIONS —At 1 year , ILI result ed in clinical ly significant weight loss in people with type 2 diabetes . This was associated with improved diabetes control and CVD risk factors and reduced medicine use in ILI versus DSE . Continued intervention and follow-up will determine whether these changes are maintained and will reduce CVD risk
