Surgery may reverse early diabetes without meds
NCT ID NCT02488733
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if weight-loss surgery (sleeve gastrectomy) can help people with newly diagnosed type 2 diabetes and a BMI of 30-42 achieve diabetes remission without medication. About 30 adults will be randomly assigned to either surgery or standard medical care and followed for up to 6 years. The goal is to see if surgery leads to better blood sugar control, weight loss, and quality of life compared to medication alone.
