A Study on the Effect of Bariatric Surgery on Glucose Metabolism in Chinese Obese and Type 2 Diabetes Patients

Obesity Clinical Trial

Official title:
A Study on the Effect of Bariatric Surgery on Glucose Metabolism in Chinese Obese and Type 2 Diabetes Patients

Clinical Trial Summary

The study will be conducted in the following population: obese patients with normal glucose tolerance (HbA1c ≤ 5.6%, n=12), pre-sugar patients (5.7% ≤ HbA1c ≤ 6.4%, n=18) and patients with T2DM (HbA1c ≥ 6.4% , n=18). After recruiting, they were followed up at 1, 3, 6, and 12 months postoperatively, and their preoperative and follow-up examination values related to demographics, body composition, blood biochemistry, and glucose metabolic balance, as well as quantitative MRI imaging and oral glucose tolerance test (OGTT) will be collected. An interim analysis will be performed at 6 months postoperatively and overall analysis will be performed at 12 months postoperatively by descriptive statistics and ANOVA methods to explore the effect of adiposity on the progression of diabetes mellitus and insulin secretory function.
