Clinical obesity

Changes in digestion movement and gut hormone levels after two types of weight-loss surgery in people with severe obesity

Updated

Abstract

After both Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), significantly accelerated.

  • Postprandial release of the GLP-1 and PYY significantly increased after both surgeries, indicating activation of the ileal brake.
  • significantly accelerated after SG but not after RYGB.
  • No significant correlations were found between changes in gut peptide release, GI motility, and clinical parameters.
  • Both SG and RYGB resulted in significant weight loss and affected GI motility and gut peptide secretion.
  • Subtle differences were observed in the effects on oro-cecal transit time and patterns of peptide secretion between the two procedures.
