How GLP-1 Medications Work Explained
What Is GLP-1?
GLP-1 stands for glucagon-like peptide-1. It's a hormone your body naturally produces that plays a key role in regulating blood sugar and appetite. GLP-1 medications are synthetic versions of this hormone.
Appetite Suppression
GLP-1 medications work on receptors in your brain that control hunger and satiety. They signal your brain that you're full sooner and longer, reducing overall food intake without willpower.
Blood Sugar Control
These medications help regulate blood glucose levels by stimulating the pancreas to produce insulin when needed and slowing gastric emptying—the rate at which food leaves your stomach.
How This Leads to Weight Loss
By reducing hunger and improving blood sugar control, GLP-1s naturally lead to a caloric deficit. You eat less without feeling deprived, which makes sustainable weight loss more achievable.
Types of GLP-1 Medications
Common GLP-1 medications include semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), and liraglutide (Saxenda). Each has slightly different dosing and mechanisms, but they work on similar principles.
