Semaglutide is a weight loss injection that falls under a class of medications called GLP-1 agonists. These medications work by mimicking the glucagon-like peptide-1 (GLP-1) hormone that your body produces when you eat, which signals to your brain that you’re full.
Semaglutide injections “trick” your brain into thinking you’re satisfied with smaller meal portions. This allows you to maintain a calorie deficit, which is when you burn more calories than you consume. GLP-1 medications also regulate blood sugar and slow your digestive system, which curbs cravings and makes you feel less compelled to snack in between meals.
