Summary

This study compares a newer weight-loss surgery called SADI-S to an older, more complex one called BPD-DS in 62 adults with severe obesity. The goal is to see if SADI-S is safer and just as effective for long-term weight loss and managing related health problems like diabetes. Researchers will track complications, weight changes, and side effects over five years.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: SADI-S (a type of weight-loss surgery that combines stomach reduction with intestinal bypass)
What this could lead to: If successful, SADI-S could offer a safer, simpler surgical option for lasting weight loss and control of obesity-related conditions like diabetes.
What could go wrong: This is a small, single-center study comparing two surgeries, so results may not apply broadly. Both procedures carry risks like malnutrition, bowel issues, and surgical complications.
