**2.10 Quality of life (QoL)**

Morbid obesity together with obesity-related diseases have a negative impact on the QoL. BS, apart from decreasing mortality and morbidity, achieves long-lasting QoL improvement. Significant improvements in physical, psychosocial, and sexual QoL are reported post LSG [37]. QoL and status of general well-being significantly improved 1 to 2 years post LSG [38, 39]. This improvement was also sustained on the long term. For instance, a 10 year follow up study reported significant increase in total QoL before and 10 years after LSG [39]. The global physical health QoL increased from 45.6 ± 20.7 to 62.3 ± 23 at 10 years; the global mental health QoL increased from 49.5 ± 17.7 to 62.2 ± 17.8; and the global total QoL score pre-surgery that was 48.3 ± 20.6 increased to 65.1 ± 21.4 at 10 years [39].
