A Systematic Review and Meta-Analysis of Outcomes for Type 1 Diabetes after Bariatric Surgery

Abstract
Background. The utility of bariatric surgery in type 1 diabetes remains controversial. The aim of the present study is to evaluate glycemic control outcomes in obese patients with type 1 diabetes after bariatric surgery. Methods. A comprehensive search of electronic databases was completed. Inclusion criteria included human adult subjects with BMI ≥35 kg/m2 and a confirmed diagnosis of type 1 diabetes who underwent a bariatric surgical procedure. Results. Thirteen primary studies (86 patients) were included. Subjects had a mean age of years with a mean BMI of  kg/m2. There was a marked reduction in BMI postoperatively at 12 months and at study endpoint to  kg/m2 () and  kg/m2 (), respectively. Preoperative weighted mean total daily insulin requirement was  IU/d, which decreased significantly to  IU/d () and  IU/d () at 12 months and at study endpoint, respectively. An improvement in HbA1c was also seen from % preoperatively to % () and % () at 12 months and at study endpoint, respectively. Conclusion. Bariatric surgery in patients with type 1 diabetes leads to significant reductions in BMI and improvements in glycemic control.
