Tirzepatide, also known as Zepbound or Mounjaro, is a newer medication that works on two different systems in your body to help manage weight and blood sugar levels. It's mainly studied for treating obesity and type 2 diabetes by reducing appetite and improving how your body handles insulin. Unlike some older weight-loss drugs, tirzepatide affects two different hormone pathways at once, which may make it more effective. There is growing human research showing it can help people lose significant amounts of weight. This medication is given as a weekly injection.
