Bariatric surgery improves patients’ well-being beyond significant weight loss and resolution of comorbidities,
Quality of Life (QoL) is a relevant but challenging variable to assess in the process of weight loss and
lifestyle changes. The primary objective of the study was to determine the QoL of patients after bariatric
surgery in comparison with obese patients who have not undergone bariatric surgery. A descriptive analytical
approach was used to collect data from 100 subjects who had undergone Laparoscopic Sleeve Gastrectomy
(LSG) through SF 36 in comparison with 100 obese subjects without surgery. 50% data collection was
done directly from OPD and 50% from telephonic contact in both the groups. The mean scores in all the
eightdimensions of SF 36 were found to be good in Bariatric Surgery (BS) group. Both Physical Component
Score (PCS) and Mental Component Score (MCS) were found to be high, the MCS being higher (85.74 +
22.72) than the PCS (83.68 + 21.8) in BS group whereas the MCS was poor in obese group (49.98 + 11.84).
The overall QoL of BS group was found to be good (mean 80.93 + 18.18) compared to obese group (49.69 +
11.77). The health related QoL was found to be quite good in patients after LSG than those without surgery.
The study concludes that the health related quality of life is better in obese patients after LSG than those
without surgery. The study also strongly recommends the conduct of long term longitudinal qualitative
studies with multiple points of measurements and follow-ups to be extended to the community.
