Summary

This study aims to evaluate changes in eating behavior attitudes, nutritional status, and appetite-regulating hormonal parameters in individuals who have undergone Laparoscopic Sleeve Gastrectomy (LSG). The study will be conducted at Bursa Yıldırım Doruk Hospital, Department of General Surgery. A total of 40 volunteer participants who underwent LSG within the last month will be included. Participants will be assessed at baseline (shortly after surgery) and at 6-month follow-up. Assessments will include anthropometric measurements (body weight, height, waist and hip circumference, BMI, waist-to-hip ratio), 3-day dietary intake records analyzed using BeBIS 8.2 software, and the Adult Eating Behavior Scale. Biochemical parameters including fasting blood glucose, total cholesterol, triglycerides, HDL, LDL, VLDL cholesterol, and insulin will be obtained from patient files and analyzed using Advia Chemistry 2400 and Advia XPT devices. Additionally, appetite-regulating hormones (ghrelin, GLP-1, PYY) will be analyzed from residual blood samples using the ELISA method with RelAssay Diagnostics kits by Teknogen Bioengineering Laboratory. All data will be compared between baseline and 6-month follow-up to evaluate the impact of bariatric surgery on nutritional and hormonal outcomes.
