First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study uses PET scans to look at the brain's reward system in 30 people who had bariatric surgery 2-3 years ago. Researchers want to see if differences in dopamine receptors explain why some patients lose more weight than others. Participants will have brain scans before and after a liquid meal to measure these changes.
