Selective beneficial cardiometabolic effects of vertical sleeve gastrectomy are predominantly mediated through glucagon-like peptide (GLP-1) in Zucker diabetic fatty rats
GLP-1 increases post-VSG 30 min after glucose load. Post-VSG GLP-1 secretion is associatged with lower cholesterol and triglycerides. Bile acids and L-PGDS increase post-VSG and are inhibited in the presence of GLP-1 antagonist. Heart rate, blood pressure and myograph profile remain unchanged.
