NCT ID NCT07414043
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 500 people who are offered prescription weight-loss drugs like Wegovy or Mounjaro. Researchers want to understand what makes someone accept or refuse these medications. They will also track those who start treatment for up to 5 years to see how well the drugs work in real life and if people stick with them.
