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.
