Abstract

Abstract Introduction Obesity impairs patients' quality of life (QoL). Laparoscopic sleeve gastrectomy (LSG) is a common procedure for patients with severe obesity; however, studies reporting changes in obesity‐related QoL are limited. The aim of this study was to assess changes in obesity‐related QoL and food tolerance in the early postoperative period. Methods We included 20 consecutive patients who underwent LSG between May 2021 and July 2023. We evaluated changes in obesity‐related QoL 6 months after surgery using an obesity and weight loss QoL questionnaire (OWLQOL) and a weight related symptom measure (WRSM). Additionally, we assessed eating satisfaction and food tolerance after surgery. Results The percentages of total weight loss and excess weight loss were 28.5% and 79.1%, respectively. OWLQOL scores and WRSM changed from 36.5 to 73.0 points and from 44.0 to 15.0 points ( p = .007, .007), respectively. The food tolerance score decreased from 25 to 21.2 points ( p < .001), while eating satisfaction showed no significant change ( p = .25). Conclusion Obesity‐related QoL is enhanced even in the early postoperative period, without sacrificing eating satisfaction. The findings of this study may provide valuable insights for patients when considering LSG.
