Abstract
Bariatric surgery has demonstrated that, besides producing significant and sustained weight loss, it can in most cases improve glycemic control and even produce diabetes remission in some patients. Objective: To analyze the effects of Roux-en-Y gastric bypass (RYGBP) in patients with BMI > 35 kg/m2 and type 2 diabetes operated in the bariatric surgery program of Dr. Miguel Pérez Carreño Hospital. Method: The investigation was descriptive, longitudinal and retrospective. The sample consisted of 20 patients attending the bariatric surgery program and underwent laparoscopic Roux-en-Y gastric bypass between 2011 and 015, with diagnosis of type 2 diabetes (T2DM). Results: After 1 year following RYGBP, significant decrease in glycaemia, glycosylated hemoglobin (HbA1c) and BMI was observed. Complete remission was observed in 75 % of patients, partial remission in 10 % and metabolic improvement in 15 %. Conclusions: RYGBP is effective in patients with T2DM, achieving a remission of 75% of treated patients
