First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tracked 46 people with severe obesity who had 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 stomach enlargement is linked to weight regain, which could help improve future surgeries.
