Részletes leírás
This observational study will be conducted at Bursa Yıldırım Doruk Hospital, General Surgery Clinic, under the supervision of Assoc. Prof. Dogukan Durak. Forty volunteer participants who underwent Laparoscopic Sleeve Gastrectomy (LSG) within the last month and meet the inclusion and exclusion criteria will be enrolled after signing an informed consent form.
Assessments will be performed at two time points: at baseline (shortly after surgery) and at 6-month follow-up.
Anthropometric Measurements: Body weight, height, waist and hip circumference will be measured. BMI and waist-to-hip ratio will be calculated accordingly. Waist circumference will be evaluated according to WHO criteria.
Dietary Assessment: A 3-day dietary intake record will be collected from each participant at both time points. Food portion sizes will be estimated using the "Food and Nutrient Photo Catalog." Energy and macronutrient intake will be analyzed using BeBIS 8.2 software and evaluated according to the Turkish Dietary Guidelines 2022 (TUBER 2022).
Eating Behavior Assessment: The Adult Eating Behavior Scale (developed by Celik et al.) will be administered at both time points. The scale consists of 18 items and 5 subscales, scored between 0-100. Higher scores indicate more positive attitudes toward eating behavior.
Biochemical and Hormonal Parameters: After 12-hour fasting, the following biochemical parameters will be obtained from patient files: fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, very low-density lipoprotein (VLDL) cholesterol, and insulin. Routine biochemical parameters and lipid profile will be analyzed spectrophotometrically using the Advia Chemistry 2400 device, while insulin will be measured by chemiluminescence using the Advia XPT device. Additionally, appetite-regulating hormones including ghrelin, glucagon-like peptide-1 (GLP-1), and peptide YY (PYY) will be analyzed from residual blood samples stored at -20°C by Teknogen Bioengineering Laboratory using the ELISA method with an automated microplate reader (Biotek TS800) and RelAssay Diagnostics commercial kits (Ankara, Turkey).
All data will be compared between baseline and 6-month follow-up using appropriate statistical methods.
