Background/purpose: Laparoscopic sleeve gastrectomy (LSG) has been defined as an innovative surgical method for the treatment of obesity and is progressively applied worldwide. However, data on result of sleeve gastrectomy regarding energy-protein status, nutrient deficiencies and body composition are limited. The purpose of this study is to search nutritional status, body composition and biochemical parameters following LSG.
Methods: Obese subjects (N:55) scheduled for sleeve gastrectomy were included. Macro-micronutrient intake analysis, biochemical blood parameters, and anthropometric measures were performed before and 1, 3 and 6 months after LSG.
Background/purpose: Laparoscopic sleeve gastrectomy (LSG) has been defined as an innovative surgical method for the treatment of obesity and is progressively applied worldwide. Nutritional deficiencies are identified as the possible complications of bariatric surgery. However, data on result of sleeve gastrectomy regarding energy-protein status, nutrient deficiencies and body composition are limited. The purpose of this study is to search nutritional status, body composition and biochemical parameters following LSG.
Methods: Obese subjects (N:55) scheduled for sleeve gastrectomy were included in this study. Preoperative and postoperative (1, 3 and 6th months) protein-energy and other nutrient consumptions, eating habits, food consumption diversity were evaluated with food frequency questionnaire, 3-days food diary record, three-factor eating scale and healthy eating index. Also in the pre- and postoperative period; anthropometric (weight, height, waist, hip, fat free mass) values measured and biochemical blood parameters were collected.

The population of the study consists of patients who received LSG surgery approval which was conducted in a special obesity clinic, Obezite Cerrahi Ankara Merkezi in Ankara, Turkey.
The decision for surgery was taken after a multidisciplinary meeting, following recommendations of international consensus conferences or expert panels American Society for Metabolic and Bariatric Surgery (ASMBS).

BMI was calculated (weight/height squared; in kilograms per square meter) |
| 6 months |
| Comparing the body fat percentage (%) of all interventions | the percentage of body fat and fat free mass (FFM) was measured by Tanita Segmental Body Composition Analyzer MC-780MA-N. | 6 months |
| Comparing the fasting blood glucose levels of all interventions | Concentration of fasting blood glucose levels baseline and changes after 1,3 and 6 months after surgery were compared. Blood samples were obtained from medical files before surgery and after 1,3,6 months of surgery period, and sera were stored at -30∘ C, until analytical measurements were performed. | 6 months |
| Comparing the serum lipid levels of all interventions | Differences in concentration of serum lipid levels of participants in baseline period and after post-operation were measured. Blood samples were obtained from medical files at baseline period (pre-operation) and after each intervention period (post-operation 1.3.6 months), and sera were stored at -30∘ C, until analytical measurements were performed. The levels of serum lipids: Triglycerides (mg/dL), Total cholesterol (mg/dL), and HDL cholesterol (mg/dL) were determined using a Dimension Xpand Plus integrated clinical chemistry autoanalyzer (Siemens Healthcare Diagnostics, USA). | 6 months |
| Comparing the serum B12 levels of all interventions | baseline, 1,3,6, months after surgery B12 blood measurements taken from patients medical files. | 6 months |
