The Impact of Bariatric Surgery on Quality of Life in Patients with Obesity

Obesity has become a widespread health problem influencing people's health, general well-being, and healthcare costs. It also represents an important risk factor for multiple comorbidities and malignancies. Objectives: the primary objective of this study was to provide notable insights to healthcare professionals regarding the management of patients with obesity, to highlight the effectiveness of bariatric surgical methods in losing excess weight, and to establish the relationship between weight loss and changes in quality of life (QoL). Material and methods: our study evaluated the QoL of 76 patients following bariatric surgery at different postoperative stages using the 36-Item Short Form Survey (SF-36) and The World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaires. Results: regarding the type of bariatric procedure performed, out of the 76 respondents, 39.47% underwent gastric bypass surgery (RYGB), 56.57% underwent sleeve gastrectomy (LSG), and only 3.94% underwent single anastomosis duodeno-ileal switch (SADI-S). Pertaining to the SF-36 questionnaire, the lowest average scores were found in the energy/fatigue subscales and in the limitations due to mental health, which remained consistent across surgery types with a significant decrease in the SADI-S group. Concerning the WHOQOL-BREF questionnaire, the lowest mean scores were found in the environment (15.03 & PLUSMN; 2.37) and social relations (16.08 & PLUSMN; 2.22) subscales, whilst the highest average scores were in physical health (16.30 & PLUSMN; 2.03) and mental health (16.57 & PLUSMN; 2.16). Conclusions: the findings revealed that whilst bariatric surgery significantly improved physical health, it resulted in a decrease in mental health scores. Consequently, the study emphasizes the importance of adopting a holistic approach to managing obesity that considers improving both physical and mental health outcomes.
