Evaluation of Metabolic Parameters, Intestinal Permeability and Gastrointestinal Symptoms After Bariatric Surgery in Body Weight Management
Sponsor: Toros University
Summary
This study aims to evaluate the changes in metabolic parameters, intestinal permeability, and gastrointestinal symptoms in individuals who have undergone bariatric surgery (Laparoscopic Sleeve Gastrectomy - LSG) for obesity treatment. Obesity is a chronic disease associated with serious health complications including type 2 diabetes, hypertension, cardiovascular disease, and metabolic disorders. Bariatric surgery is currently the most effective treatment method for morbid obesity. However, monitoring patients after surgery in terms of metabolic health, gut permeability, and gastrointestinal symptoms is crucial for long-term success. In this study, 40 volunteers (aged 19-50) who have undergone LSG surgery within the last month will be followed for 6 months. At the beginning of the study and 6 months later, the following will be assessed: * Metabolic parameters: fasting blood glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) cholesterol, and insulin levels * Intestinal permeability markers: zonulin, secretory immunoglobulin A (IgA), and lipopolysaccharide (LPS) levels * Gastrointestinal symptoms: assessed using the Gastrointestinal Symptom Rating Scale (GSRS) * Anthropometric measurements: body weight, height, waist and hip circumference, BMI * Nutritional intake: 3-day dietary records The study will be conducted at Bursa Yıldırım Doruk Hospital, General Surgery Clinic. Results will contribute to understanding the relationship between bariatric surgery and gut health, potentially helping to prevent postoperative complications.

Clinical and Biochemical Assessment
Participants will undergo two assessment visits: at baseline (within 1 month post-surgery) and at 6-month follow-up. Each visit includes anthropometric measurements (body weight, height, waist and hip circumference, BMI), biochemical blood analysis (fasting glucose, lipid profile, insulin, zonulin, secretory IgA, LPS), gastrointestinal symptom evaluation via GSRS, and 3-day dietary records.
