Semaglutide is a medication primarily used to treat type 2 diabetes and support weight loss. It belongs to a class of drugs known as GLP-1 receptor agonists (glucagon-like peptide-1), which mimic a natural hormone in the body that helps regulate blood sugar, appetite, and digestion.
How Semaglutide Works
Semaglutide works by:
-
Stimulating insulin release when blood sugar levels are high
-
Suppressing the release of glucagon (a hormone that raises blood sugar)
-
Slowing gastric emptying, which helps you feel full longer
-
Reducing appetite, leading to decreased food intake
