Study on Brain Function of Obesity Classification

Status Recruiting

Clinical Trial Summary

The purpose of this study was to investigate the differences and similarities of brain function in patients with four subtypes of obesity, and the relationship between brain function changes and complications after weight loss and metabolic improvement. 120 patients with obesity and 30 healthy individuals with normal BMI were enrolled.

Clinical Trial Description

Although the investigators have clinically observed significant differences in appetite and metabolic status in patients with the above four types of obesity, the brain functional characteristics of different obesity subtypes and their relationship with metabolic markers are still unclear. Based on this, in this project, the investigators plan to explore further the similarities and differences in brain function in patients with four subtypes of obesity and the relationship between brain function changes after weight loss and metabolic improvement and the occurrence of complications. 120 patients with obesity and 30 healthy individuals with normal BMI were enrolled. All patients with obesity underwent LSG. A multidisciplinary team evaluated participants with obesity at baseline, 1, 3, 6, and 12 months after laparoscopic sleeve gastrectomy (LSG). Anthropometrics, Metabolic indicators, sex hormones, menstruation，glucose-lipid metabolic markers, and hepatic steatosis assessed by FibroScan(CAP value and E value) were measured baseline and postoperative. Resting and task state functional magnetic resonance imaging (fMRI) measurements were performed at baseline for all participants at two-time points before and after meals. Measurements were repeated in obese patients 6 months after surgery. ;
