Psychological Outcome Two Years after Restrictive Bariatric Surgery
- First Online:
An essential outcome criterion of obesity surgery besides weight loss is the improvement of medical and psychological health status. Both dimensions influence quality of life. This study evaluates depressive symptoms, self-esteem and health-related quality of life 2 years after bariatric surgery.
149 patients (47 males (32%), 102 females (68%), mean age 38.8 ± 10.3 years) were assessed by standardized questionnaires before and 1 and 2 years after gastric restrictive surgery.
Mean BMI pre-surgery was 51.3 ± 8.4 kg/m2. BMI decreased significantly to 38.6 ± 6.8 kg/m2 at 1 year and to 37.9 ± 7.4 kg/m2 at 2 years after surgery. Statistical analyses revealed a significant decrease in depressive symptoms and a significant improvement in selfesteem and the physical dimension of health-related quality of life. Pre-surgery, 40.5% (n = 62) of the patients suffered from depressive symptoms of clinical relevance. These depressive symptoms persisted in 17.7% (n = 27) 1 year and in 16.4% (n = 25) 2 years after surgery.
Parallel with a considerable weight loss after bariatric surgery, important aspects of mental health such as depressive symptoms and selfesteem improved significantly. These effects appear 1 year after surgery, but do not seem to change considerably afterwards.
