English: The digestive system and blood sugar levels are regulated by GLP-1 (glucagon-like peptide 1), as the above visual shows. The small intestine releases GLP-1 when food is eaten, which has an impact on multiple organs. It suppresses hunger in the stomach and alerts the brain to feel full, which results in less food being consumed. In addition, GLP-1 causes the pancreas to secrete insulin, which lowers blood sugar. Additionally, GLP-1 prevents the pancreas from secreting glucagon, which normally boosts blood sugar levels. In doing so, glucose homeostasis is preserved.

If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “GLP-1 Signaling in the Body.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

GLP-1 regulates digestion and blood sugar. The small intestine releases GLP-1 when food is eaten. It reduces hunger, signals fullness, stimulates insulin, and inhibits glucagon, maintaining glucose levels.
