Summary

This study looked at 18 women who had sleeve gastrectomy surgery 2-3 years earlier. Researchers compared stomach emptying rates between those who lost a lot of weight (over 35% of total weight) and those who lost little (under 25%). They used MRI and a special scan to measure how fast food leaves the stomach, aiming to understand why some people lose more weight than others after this surgery.
