How Do GLP-1 Medications Work?
Last updated: January 2026
Quick Answer
GLP-1 receptor agonists mimic the natural GLP-1 hormone released after eating. They slow stomach emptying, signal the brain's satiety centers to reduce hunger, increase insulin production, and decrease glucagon. The result is dramatically reduced appetite and calorie intake.
