  5. Mounjaro or Ozempic: Which Works Best for Diabetes and Weight Loss?

When treating type 2 diabetes, finding the right medication can feel complicated. Medicines like Mounjaro and Ozempic have gained popularity for their ability to control blood sugar, alongside aiding weight loss. With so many options available, choosing the best fit for your needs—and managing the process through a virtual care platform like WebDoctors—can make all the difference. Below, we answer your frequently asked questions and help guide your decision-making.

How Do Mounjaro and Ozempic Work? 

Both medications help control blood sugar and promote weight loss, but they work on different hormonal pathways:

  • Ozempic (Semaglutide): Mimics the GLP-1 hormone, which slows digestion, curbs hunger, and prompts the pancreas to release more insulin. 
  • Mounjaro (Tirzepatide): Acts on both GLP-1 and GIP hormones—making it more potent for improving blood sugar and encouraging weight loss. 

Mounjaro operates through two pathways, resulting in better diabetes control and weight management.
