How does Mounjaro work?
Mounjaro is a glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist. It works by acting like GLP-1 and GIP, two hormones released by your gut after you eat to help you control blood sugar. These hormones tell your body to release more insulin, release less sugar, and slow down digestion. All of these actions help lower blood sugar levels. In people who have Type 2 diabetes, GLP-1 and GIP don’t work as well they should. So Mounjaro helps by acting just like GLP-1 and GIP to help control blood sugar.
