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 question naires is it hard to make a distinction between different surgeries and difficult to see a relation with medical profit .
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 prospect i ve evidence regarding the short and long-term effects of bariatric surgery on Quality of Life ( QoL ) and a comparison with community norms .
Prognostic Significance of Depressive Symptoms on Weight Loss and Psychosocial Outcomes Following Gastric Bypass Surgery: A Prospective 24-Month Follow-Up Study
Background This study examined the prognostic significance of depressive symptoms in bariatric surgery patients over 24 months of follow-ups . Methods Three hundred fifty-seven patients completed a battery of assessment s before and at 6 , 12 , and 24 months following gastric bypass surgery .  In addition to weight loss and depressive symptoms , the assessment s targeted eating disorder psychopathology and quality of life . Results Clinical ly significant depressive symptoms , defined as a score of 15 or greater on the Beck Depression Inventory , characterized 45 % of patients prior to surgery , and 12 % at 6-month follow-up , 13 % at 12-month follow-up , and 18 % at 24-month follow-up . Preoperative depressive symptoms did not predict postoperative weight outcomes . In contrast , postsurgery depressive symptoms were predictive of weight loss outcomes . Higher postsurgery depressive symptoms at each time point predicted a greater degree of concurrent and subsequent eating disorder psychopathology and lower quality of life . Conclusions The frequency of elevated depressive symptoms decreases substantially following gastric bypass surgery but increases gradually over 24 months . Postoperative depressive symptoms are significantly associated with poorer weight outcomes at 6 and 12 months following surgery but do not predict longer-term weight outcomes at 24 months . Postoperative depressive symptoms prospect ively predict greater eating disorder psychopathology and poorer quality of life through 24 months . Elevated depressive symptoms , readily assessed by self-report , may signal a need for clinical attention after surgery
