Brief summary

This study aims to evaluate the nutritional status of morbidly obese patients following gastric bypass surgery. Data from 76 patients aged 19-64, who will be monitored by a dietitian for at least six months, will be analyzed. Preoperative and postoperative biochemical parameters along with anthropometric measurements will assess.

Detailed description

Objective: This retrospective study aims to evaluate the nutritional status of morbidly obese patients in the first six months following sleeve gastrectomy. Methods: The study is planned as a retrospective analysis. The data of 76 patients aged 19-64 years who underwent bariatric surgery and were monitored by a dietitian for at least six months will be included in the study. Preoperative and postoperative biochemical parameters and anthropometric measurements of the patients will be collected and analyzed. Detailed Description: The study will assess the changes in nutritional status, including body weight, BMI, fasting blood glucose, HbA1c, Homa-IR, iron levels, vitamin D levels, and lipid profile (triglycerides, LDL, HDL) among morbidly obese patients in the first six months following sleeve gastrectomy. Preoperative and postoperative measurements will be compared to evaluate the impact of surgery on these parameters. Conclusion: Results will be analyzed and interpreted after data collection is completed, and conclusions will be drawn accordingly.
