Summary
This study followed 46 people with severe obesity who had either gastric bypass or sleeve gastrectomy. Researchers used a special CT scan with gas to measure stomach volume at 3 and 12 months after surgery. The goal was to see if an increase in stomach size is linked to weight regain. The findings could help doctors better understand and manage long-term weight loss success.
