Correlation between Preoperative Dietary Dehavior and Weight Loss after Laparoscopic Sleeve Gastrectomy

Purpose: The study aimed to investigate the relationship between preoperative dietary habits and weight loss in individuals with simple obesity who have undergone laparoscopic sleeve gastrectomy. Methods: From January 2020 to August 2021, the clinical data of 75 patients with simple obesity who underwent laparoscopic sleeve gastrectomy at the Department of Gastrointestinal Surgery, The First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed, including gender, age, height, weight, calculated percentage of total weight loss (TWL), percentage of excess weight loss (%EWL), and the three-factor diet questionnaire, and correlation tests were performed. Results: At 1 month, 3 months, and 1 year postoperatively, postoperative follow-up weight and BMI were considerably reduced (P 0.001), while %TWL and %EWL levels were significantly higher (P 0.001). Emotional eating (EE) and unrestrained eating habits (UE) reduced considerably 1 month postoperatively (P 0.001). There was no significant link between preoperative CR and %TWL and %EWL at 1 month, 3 months, or 1 year postoperatively, while preoperative EE and UE were marginally positively connected with %TWL and %EWL at 1 month (r > 0.3, P＜0.05). Conclusions: Following LSG, dietary habits improved dramatically, and preoperative EE and UE were shown to be weakly closely connected with early weight loss in obese patients after LSG.
