GLP-1

GLP-1 (Glucagon-Like Peptide-1) is a natural gut hormone that helps regulate blood sugar by boosting insulin, suppressing glucagon, slowing digestion, and signaling fullness, leading to reduced appetite and weight loss; synthetic GLP-1 receptor agonists (like Ozempic, Wegovy, Victoza) mimic these effects and are widely used for managing Type 2 diabetes and obesity, working by binding to GLP-1 receptors in the brain and body to control glucose and hunger.
