Abstract

Background: Obesity is a globally increasing health problem that has a significant impact on the health of individuals. Gastric bypass is a type of bariatric surgery that is considered to be an effective treatment for obesity in case of failure of non-operative interventions. It is thought that gastric bypass improves the quality of life (QoL) of the patient as it reduces the weight of the patient significantly and reduces the risks of the adverse effects of obesity. The aim of this study was to evaluate the QoL of patients after performing the gastric bypass surgery.
Methods: This cross-sectional study was conducted among patients who underwent gastric bypass surgery during the period from August to November 2020. The patients were investigated for their demographics and their QoL regarding five scales used in the short form 36-item questionnaire. The analysis of the data was conducted through the Statistical Package for the Social Sciences program version 21.
Results: We enrolled 806 patients who underwent gastric bypass surgery, 59.3% were female, and 28.8% were less than 30 years old. The majority of patients were from the central region (86.1%). The significance between the QoL before and after the surgery for each item investigated was as follow: mental health (p = 0.3), vitality (p = 0.09), role of emotional (p = 0.1), general health (p = 0.005), social functioning (p = 0.8), and the total QoL
(p = 0.1).
Conclusion: The QoL of patients before and after the surgery did not differ, except for general health, which was observed to be improved after the surgery.
