Abstract

Currently the effects of bariatric surgery are generally expressed in excess weight loss or comorbidity reduction. Therefore the aim of this review was to provide insight in the available prospective evidence regarding the short and long-term effects of bariatric surgery on Quality of Life (QoL) and a comparison with community norms. A systematic multi-database search was conducted for 'QoL' and 'Bariatric surgery'. Only prospective studies with QoL before and after bariatric surgery were included. The 'Quality Assessment Tool for Before-After Studies with No Control Group' was used to assess the methodological quality. Thirty-six studies met the inclusion criteria. Most studies were assessed to be of 'fair' to 'good' methodological quality. Ten different questionnaires were used to measure QoL. Follow-up ranged from 6 months to 10 years, sample sizes from 26 to 1276 and follow-up rates from 45 to 100%. A significant increase in QoL after bariatric surgery was found in all studies (P⩽0.05), however, mostly these outcomes stay below community norms. Only outcomes of the IWQoL, SF-36 and OWQoL show QoL outcomes that exceed community norms. The QoL is increased after bariatric surgery on both the short and long term. However, due to the heterogeneity of the studies and the generality of the questionnaires is it hard to make a distinction between different surgeries and difficult to see a relation with medical profit. Therefore, tailoring QoL measurements to the bariatric population is recommended as the focus of future studies.
