Summary

This study compares three types of weight-loss surgery (sleeve gastrectomy, gastric bypass, and duodenal switch) with standard medical care for people with type 2 diabetes and a BMI of 35 or higher. The goal is to see which approach leads to long-term diabetes remission and improves related conditions like kidney and heart health. About 408 participants will be followed over time to measure outcomes.

What this could mean

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

Active substance: bariatric surgery (sleeve gastrectomy, gastric bypass, or duodenal switch)
What this could lead to: If successful, this could show that bariatric surgery is more effective than medication alone for achieving long-term diabetes remission and improving related health issues.
What could go wrong: This is an observational study, not a randomized controlled trial, so results may be less definitive. Surgery carries risks like infection, nutrient deficiencies, and complications, and not all patients may achieve remission.
