An Indian multicentre real-world study on long-term quality of life outcomes following bariatric surgery

Abstract

Background: The purpose of this study was to assess the impact of metabolic and bariatric surgery (MBS) on Quality of Life (QoL) in Indian patients with obesity over 10 years.

Methods: A retrospective chart review was conducted at 11 centres for individuals with MBS between February 2013 and May 2022. Patient medical records provided the source of de-identified data.

Results: Data from 2132 individuals with a mean age of 43.28 ± 11.96 years was analysed. There were 37.43% men and 62.57% females in the study population. The study population had a mean preoperative body mass index (BMI) of 45.71 ± 10.38 kg/m². The Bariatric Analysis and Reporting Outcome System (BAROS) scoring method showed a higher overall QoL score throughout all follow-up periods, with 'very good' outcomes at one, three and 7 years and 'good' outcomes at 5 and 10 years. Improvements in QoL were associated with a substantial improvement (p < .01) in BMI at every follow-up time point.

Conclusions: Following MBS, individuals with obesity exhibited a substantial and long-term improvement in their overall QoL for up to 10 years. This study presents Indian data on QoL, which is considered one of the most important decision-making factors for or against an intervention.
