Overview

decipher the role of microbiota in glycemic response change after bariatric surgery

Detailed description

Despite the vast knowledge linking the gut microbiome to metabolism and the glucose response, the relation still remains unclear. hopefully, a deep understanding of the mechanisms underlying metabolic improvement following bariatric surgery will make it possible to identify targets for pharmacological intervention, which will reduce the need for surgery and its risks.

Previous studies have characterized the microbiome after bariatric surgery, but most suffer from methodological limitations.

The current study has the potential to be innovative and make a significant contribution to understanding the mechanisms involved in early metabolic improvement after bariatric surgery.

Interventions

  • Procedure sleeve gastrectomy surgery
    participants undergoing sleeve gastrectomy surgery
  • Procedure gastric bypass surgery
    participants undergoing gastric bypass surgery
  • Procedure control
    cholecystectomy
  • Procedure Pancreatectomy
    Collecting a sample of an unidentified healthy pancreas to extract insulin-secreting beta cells from the sample

Primary outcome measures

  • Glycemic response [Time frame: up to 4 years]
  • microbiota composition [Time frame: up to 4 years]
