Semaglutide, a GLP-1 (glucagon-like peptide) agonist, is a medication treatment for type 2 diabetes, obesity, and weight loss. It works by increasing insulin secretion and slowing digestion, making you feel fuller longer and less hungry. In combination with a healthy diet and regular exercise, Semaglutide clinical trials have shown significant weight loss results of around 15% of total body weight, in addition to reducing the risk of cardiovascular events.
