Which weight loss surgery works best for teens? study aims to find out

NCT ID NCT02004561

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

Summary

This study follows 26 severely obese teenagers aged 14-19 who chose to have one of three weight loss surgeries: gastric band, sleeve gastrectomy, or gastric bypass. Researchers track weight, body fat, blood sugar, and vitamin levels over time to see which surgery is safest and most effective. Since teens chose their own surgery, results may be biased, but the goal is to guide better treatment decisions for young people struggling with obesity.
