What this trial studies

This observational study aims to recruit 1,000 obese patients with type 2 diabetes mellitus (T2DM) across Taiwan, focusing on those with a BMI over 25 and who have been under medical management for at least six months. The study will evaluate the natural course of diabetes over a 10-year period, assessing primary outcomes such as HbA1c levels, LDL cholesterol, and blood pressure annually after intervention. By comparing outcomes in patients who undergo metabolic surgery with those who do not, the study seeks to provide significant insights into the effectiveness of bariatric surgery in managing T2DM.

Who should consider this trial

Good fit: Ideal candidates for this study are obese individuals aged 20 to 67 with medically controlled T2DM for more than six months and a BMI over 25.

Not a fit: Patients with recent cancer diagnoses, HIV, active tuberculosis, or other serious health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable evidence on the long-term benefits of metabolic surgery for managing type 2 diabetes in mildly obese patients.

How similar studies have performed: Other studies have indicated the potential effectiveness of metabolic surgery in managing T2DM, but this specific approach is still being evaluated.
