Effect of Gastric Bypass Surgery on Pancreatic Islets and Incretin Function — AB-CD-10  

Obesity Clinical Trial

Official title:
The Effect of Gastric Bypass Surgery on the Beta- and Alpha Cells Secretory Function and the Insulinotropic Effect of the Incretin Hormones

Clinical Trial Summary

The study aims at describing the acute and subacute changes after Roux-en-Y (RYGB) gastric bypass in insulin secretion from the beta cell and glucagon secretion from the alpha cell as well as the stimulatory effect of the incretins on the pancreatic islets. RYGB is a bariatric procedure that changes the gastrointestinal anatomy and has been demonstrated to cause remission of type 2 diabetes shortly after the operation, before any significant weight loss. The altered transit of nutrient through the gastrointestinal tract after the operation is thought to play a key role in this remission and studies have shown significant changes in the secretion of gut hormones, namely the incretin hormone glucagon-like peptide-1 (GLP-1). However it is unknown whether the secretory function of the pancreatic islets as well as the stimulatory effect of the incretin hormones is changes postoperatively.
