Abstract Purpose Conditions associated with surgical technique and postoperative lifestyle changes, as well as the characteristics of patients, may affect weight loss following laparoscopic sleeve gastrectomy. In this study, the effects of age, gender, BMI, and excess weight at the time of surgery on weight loss during follow-up were examined. Materials and Methods Demographic data (age, gender), preoperative BMI, and weight values of the patients were recorded. TWL% and EWL% values of patients were recorded during follow-up at 1st, 3rd, 6th, 9th, 12th, and 18th months. Patients were grouped according to age (AGE1 < 30, AGE2 30–50, AGE3 ≥ 50 years), BMI at the time of surgery (BMI1 ≤ 50, BMI2 > 50 kg/ m2), and EW at the time of surgery (EW1 ≤ 60, EW2 > 60 kg). EWL% values obtained in the follow-up visits were compared among the gender, age, BMI, and EW groups. Results A total of 456 patients (371 females, 85 males) were operated. Mean EWL% was lower in AGE3 group (p < 0.001). Patients in AGE1 group had the highest mean EWL%, while those in BMI2 and EW2 groups had lower mean EWL% values throughout the follow-up period (p < 0.001). Regression analysis showed that age and BMI were associated with EWL% at all follow-up visits (p < 0.05). Conclusion Patients with less than 60 kg of excess weight, those with BMI ≤ 50 kg/m2 and younger patients may lose weight more effectively following LSG. Keywords Sleeve gastrectomy .

Introduction Obesity continues to be a major problem all over the world, especially in western countries. In the fight against obesity, bariatric surgery is one of the most effective and sustainable solutions [1, 2]. In recent years, the number of bariatric surgeries performed all over the world has increased significantly, and the applicability of laparoscopic sleeve gastrectomy (LSG) in the treatment of morbid obesity and obesity-related diseases has become widespread.

The reasons include technical ease, lack of malabsorptive problems, no need for gastrointestinal anastomosis, short operation time, and similar long-term results with complicated procedures [3]. The management of obesity usually starts with comprehensive lifestyle management that comprises dietary regulation, increasing physical activity, and behavior modification. Lifestyle change after LSG, protein-rich diet, and exercise are the parameters that positively affect the excess weight loss (EWL) rate [4, 5]. However, in the postoperative period, the same EWL rates cannot be achieved in all patients despite adherence to proper diet an
