Surgery results in greater improvement in weight loss outcomes and weight associated comorbidities compared with non-surgical interventions , regardless of the type of procedures used .
When compared with each other , certain procedures result ed in greater weight loss and improvements in comorbidities than others .
Outcomes were similar between RYGB and sleeve gastrectomy , and both of these procedures had better outcomes than adjustable gastric b and ing .
For people with very high BMI , biliopancreatic diversion with duodenal switch result ed in greater weight loss than RYGB .
Isolated sleeve gastrectomy led to better weight-loss outcomes than adjustable gastric b and ing after three years follow-up .

Two-year changes in health-related quality of life in gastric bypass patients compared with severely obese controls.
BACKGROUND Few weight loss surgery trials have evaluated the changes in health-related quality of life ( HRQOL ) relative to obese individuals not participating in weight loss interventions . In a prospect i ve study at a bariatric surgery practice , we evaluated the 2-year changes in HRQOL in gastric bypass patients compared with 2 severely obese groups who did not undergo surgical weight loss .  METHODS A total of 308 gastric bypass patients were compared with 253 individuals who sought but did not undergo gastric bypass and 272 population -based obese individuals using the weight-related ( Impact of Weight on Quality of Life-Lite ) and general ( Medical Outcomes Study 36-item Short-Form Health Survey ) HRQOL question naires at baseline and 2 years of follow-up . RESULTS The percentage of weight loss was 34.2 % for the gastric bypass and 1.4 % for the no gastric bypass groups , with a .5 % gain for population -based obese group . Both measures of HRQOL showed greater improvements for the gastric bypass group , even after controlling for baseline differences . Effect sizes for changes in physical and weight-related HRQOL were very large for gastric bypass , but small to medium for the 2 comparison groups . Effect sizes for changes in the psychosocial aspects of HRQOL were moderate to very large for gastric bypass , but small for the 2 comparison groups . Of the gastric bypass patients , 97 % had meaningful improvements in the Impact of Weight on Quality of Life-Lite total score compared with 43 % of the no gastric bypass group and 30 % of the population -based obese group . CONCLUSION Dramatic improvements had occurred in weight-related and physical HRQOL for gastric bypass patients at 2 years after surgery compared with 2 severely obese groups who had not undergone surgery . These results support the effectiveness of gastric bypass surgery in improving patients ' HRQOL
