Background: The global obesity pandemic is still getting worse. The only effective
treatment for morbid obesity that produces significant and long-lasting weight
loss, the resolution of obesity-related comorbidities, and long-term improvement
in quality of life is bariatric surgery. Method: A search was conducted between
2015 and 2023 through PubMed, Scopus, and Google Scholar for studies that
examined quality of life, or patient satisfaction, as an outcome measure in
patients who had undergone bariatric surgery of any kind and were following up
for at least six years. The study excluded data on weight loss that was not
consistently reported or study findings unrelated to quality of life or patient
satisfaction. Results: According to Grönroos et al., (2021) increased weight loss
was associated with improved QoL. Mean DSQoL scores after 7 years
significantly improved as compared with baseline, in contrast to median HRQoL
ratings. The 2017 study by De-Jong and Hinnen, (2017) demonstrates that further
therapies are required to improve postoperative adherence to behavioural
instructions. Ten years after the surgery, patients' overall mental health,
neuroticism, and fear of intimacy all showed a discernible fall from their preoperative
levels, according to a 2016 study by (Canetti et al., 2016). At the end of
the follow-up, participants in Askari et al., (2020) study reported feeling better,
exercising more, and developing healthier eating habits. Conclusion: Improved
QoL was linked to increased weight loss, and bariatric surgery produced a
significant long-term improvement in QoL. Postoperative adherence to
behavioural guidelines and psychosocial functioning need adjunctive therapy.
