Background: The aim of this study was to assess the eating profile of patients after laparoscopic sleeve gastrectomy (LSG) and its impact on weight loss.
Methods: One hundred ten patients who underwent LSG were interviewed using Suter questionnaire and revised Questionnaire on Eating and Weight Patterns in follow-up visits. Eating patterns were assessed preoperatively and postoperatively. Patients were divided into six groups according to the timing point of assessment. Group 1 (n = 10) included patients < 3 months, group 2 (n = 11) 3-6 months, group 3 (n = 11) 6-12 months, group 4 (n = 39) 1-2 years, group 5 (n = 23) 2-3 years, and group 6 (n = 16) > 3 years. The excess weight loss (EWL) was correlated with the results.
Results: The total score of the Suter questionnaire was 15.0 ± 5.87, 20.3 ± 7.07, 26.2 ± 1.54, 23.8 ± 4.25, 24.65 ± 2.8, and 23.43 ± 4.14 for the groups 1-6, respectively (p < 0.0001). No significant differences were denoted when long-term follow-up groups 3 to 6 were compared. No association was found between the preoperative eating pattern and EWL. Postoperatively, 91 patients modified their eating pattern. Postoperative eating pattern was significantly correlated with EWL (p = 0.015). Patients with normal and snacking eating pattern achieve the best EWL (63.57 ± 21.32 and 60.73 ± 20.62, respectively). Binge eating disorder and emotional patterns had the worst EWL (42.84 ± 29.42 and 34.55 ± 19.34, respectively).
Conclusions: Better food tolerance is detected after the first postoperative year after LSG. The postoperative eating patterns seem to affect excessive weight loss.
