Diabetes Remission After Bariatric Surgery: A 10-Year Follow-Up Study

Area of Science:

• Metabolic surgery
• Endocrinology
• Diabetes management

Background:

• Obesity presents challenges in managing type 2 diabetes (T2DM).
• Metabolic and bariatric surgery (MBS) shows promise for T2DM remission in obese patients.
• Durability of glycemic improvements after MBS requires further study.

Purpose of the Study:

• To determine the incidence of durable T2DM remission and relapse 10 years after MBS.
• To characterize the long-term glycemic profile post-MBS.
• To identify predictors of persistent T2DM remission.

Main Methods:

• Retrospective observational study of T2DM patients undergoing MBS (2010-2013).
• Clinical and analytical assessments at baseline, 2 years, and 10 years post-surgery.
• Statistical analyses included paired t-tests, Wilcoxon-signed-rank, McNemar tests, and logistic regression for predictor identification.

Main Results:

• Ten years post-MBS, 31% achieved complete T2DM remission, 15% partial remission, with a 24% late recurrence rate.
• Lower preoperative HbA1c and fewer antidiabetic drugs predicted long-term remission.
• Sustained improvements in fasting plasma glucose, HbA1c, and reduced medication use were observed at 10 years.

Conclusions:

• MBS induces significant and sustainable T2DM improvement and remission.
• Early intervention in T2DM patients with good glycemic control and low medication needs is key for lasting benefits.
• MBS offers a potential long-term solution for T2DM management in obese individuals.
