It is well established that Health Related Quality of Life (HRQoL) improves following bariatric surgery. We aimed to specifically investigate changes in HRQoL and gastrointestinal symptoms in patients undergoing three different types of bariatric surgery: OAGB, RYGB and LSG.
209 consecutive patients in a large regional bariatric clinic completed SF-36 and SAGIS questionnaires prior to undergoing bariatric surgery. The questionnaires were then repeated at the six- and twelve- month marks. Data was analysed on SPSS v26 using paired t-tests and one way ANOVA with Bonferonni analysis.
Of the 209 patients, 169 patients completed six-month and 127 completed twelve-month questionnaires.
HRQoL improved both overall and in all 7 SF-36 domains at the six-month mark (p<0.01). These results were unchanged at 12 months. There was no difference in HRQoL outcomes between the surgery subtypes.
OAGB and RYGB patients had looser bowel motions at the 6-month mark compared to LSG. However, this difference did not affect HRQOL and was eliminated at 12 months.
Patient HRQoL is improved by bariatric surgery. This improvement peaks at 6 months and is maintained at 12 months. Despite OAGB and RYGB inducing looser bowel motions at 6 months, this is temporary and does not impact HRQoL outcomes, which are unaffected by surgery type at 6 and 12 months.
