Bariatric surgery
is the most effective treatment for severe obesity. The mean weight loss is
approximately 30-40 kg/11-15 BMI units or approximately 60 % of excess body
weight.
Many patients
pursue bariatric
surgery for improvement in their physical image and self-esteem rather than
somatic health improvement.
Health-related quality
of life improves after bariatric surgery and the long-term improvements are
positively associated with the long-term amount of weight reduction.
