GLP-1 Receptor Agonists (Weight Loss & Diabetes)
The most talked-about drug class in America. GLP-1s treat Type 2 diabetes and obesity, with blockbuster drugs like Ozempic, Wegovy, and Mounjaro.
How GLP-1 Receptor Agonists Work
GLP-1 receptor agonists mimic the gut hormone GLP-1, which tells the brain you're full and tells the pancreas to release insulin. They slow stomach emptying, reduce appetite, and improve blood sugar control. Dual GIP/GLP-1 agonists (tirzepatide in Mounjaro/Zepbound) activate two incretin pathways for even greater effect.
