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 .
Anemia and the Need for Intravenous Iron Infusion after Roux-en-Y Gastric Bypass
The frequency of anemia , iron deficiency , and the long-term need for IV iron  following Roux-en-y gastric bypass ( RYGB ) surgery  has not been well characterized . Three-hundred and nineteen out of 904 consecutive subjects who underwent RYGB at Penn State Hershey Medical Center from 1999 to 2006 met the inclusion criteria for a preoperative complete blood count ( CBC ) and at least one CBC > 6 months following surgery . Cumulative incidence of anemia 7 years post procedure was 58 % . Menstruation status and presence of preoperative anemia were predictive of anemia by univariate analysis and multivariable Cox regression ( P= 0.0014 and 0.044 , respectively ) . Twenty-seven subjects , primarily premenopausal women , representing 8.5 % of the cohort and 22 % of the 122 anemic subjects , needed intravenous ( IV ) iron  a mean of 51 months postoperatively for anemia unresponsive or refractory to oral iron . The risk for development of anemia necessitating IV iron therapy following RYGB is highest in menstruating women and continues to increase for many years , even in post-menopausal women . Well- design ed prospect i ve studies are needed to identify the incidence of iron deficiency anemia and the patient population s at increased risk for requiring IV iron replacement after RYGB surgery
