Diabetes remission and reduced cardiovascular risk after gastric bypass in Asian Indians with body mass index <35 kg/m(2).
BACKGROUND Roux-en-Y gastric bypass ( RYGB ) benefits patients with type 2 diabetes mellitus ( T2DM ) and a body mass index ( BMI ) > 35 kg/m(2 ) ; however , its effectiveness in patients with T2DM and a BMI < 35 kg/m(2 ) is unclear . Asian Indians have a high risk of T2DM and cardiovascular disease at relatively low BMI levels . We examined the safety and efficacy of RYGB in Asian Indian patients with T2DM and a BMI of 22 - 35 kg/m(2 ) in a tertiary care medical center . METHODS A total of 15 consecutive patients with T2DM and a BMI of 22 - 35 kg/m(2 ) underwent RYGB .  The data were prospect ively collected before surgery and at 1 , 3 , 6 , and 9 months postoperatively . RESULTS Of the 15 patients , 8 were men and 7 were women ( age 45.6 + /- 12 years ) . Their preoperative characteristics were BMI 28.9 + /- 4.0 kg/m(2 ) , body weight 78.7 + /- 12.5 kg , waist circumference 100.2 + /- 6.8 cm , and duration of T2DM 8.7 + /- 5.3 years . At baseline , 80 % of subjects required insulin , and 20 % controlled their T2DM with oral hypoglycemic medication . The BMI decreased postoperatively by 20 % , from 28.9 + /- 4.0 kg/m(2 ) to 23.0 + /- 3.6 kg/m(2 ) ( P < .001 ) . All antidiabetic medications were discontinued by 1 month after surgery in 80 % of the subjects . At 3 months and thereafter , 100 % were euglycemic and no longer required diabetes medication . The fasting blood glucose level decreased from 233 + /- 87 mg/dL to 89 + /- 12 mg/dL ( P < .001 ) , and the hemoglobin A1c decreased from 10.1 % + /- 2.0 % to 6.1 % + /- 0.6 % ( P < .001 ) . Their waist circumference , presence of dyslipidemia , and hypertension improved significantly . The predicted 10-year cardiovascular disease risk ( calculated using the United Kingdom Prospect i ve Diabetes Study equations ) decreased substantially for fatal and nonfatal coronary heart disease and stroke . No mortality , major surgical morbidity , or excessive weight loss occurred . CONCLUSION RYGB safely and effectively eliminated T2DM in Asian Indians with a BMI < 35 kg/m(2 ) . Larger , longer term studies are needed to confirm this benefit
