PYY in Gut Physiology and Obesity: Complete Role From Digestion to Body Weight
PYY's roles extend beyond appetite suppression to comprehensive gut physiology regulation: gastric emptying, intestinal motility, pancreatic secretion, and fluid absorption — with PYY deficiency contributing to obesity.
Quick Facts
What This Study Found
PYY integrates multiple gut functions: suppresses appetite (Y2R-mediated), slows gastric emptying, reduces intestinal motility, decreases pancreatic secretion, and promotes fluid absorption — PYY deficiency in obesity contributes to the disordered satiety driving overeating.
