BACKGROUND Obesity is associated with increased mortality. [] Key Method At the time of the analysis (November 1, 2005), vital status was known for all but three subjects (follow-up rate, 99.9%). RESULTS The average weight change in control subjects was less than +/-2% during the period of up to 15 years during which weights were recorded. Maximum weight losses in the surgical subgroups were observed after 1 to 2 years: gastric bypass, 32%; vertical-banded gastroplasty, 25%; and banding, 20%.

Bariatric surgery and reduction in morbidity and mortality: experiences from the SOS study
TLDR
Bariatric surgery for severe obesity is associated with long-term weight loss, improved risk factors and decreased overall mortality over an average of 10 years.
Bariatric Surgery and Long-Term Mortality
TLDR
Two groups now address the effect of bariatric surgery on long-term mortality in obese patients prospectively, with findings that suggest that patients who lose weight live longer than those who do not.
Effects of bariatric surgery on cancer incidence in obese patients in Sweden (Swedish Obese Subjects Study): a prospective, controlled intervention trial.
Feasibility of Bariatric Surgery as a Strategy for Secondary Prevention in Cardiovascular Disease: A Report from the Swedish Obese Subjects Trial
TLDR
Bariatric surgery appears to be a safe and feasible treatment to achieve long-term weight loss and improvement in cardiovascular risk factors, symptoms, and quality of life in obese subjects with ischemic heart disease.
Review of the key results from the Swedish Obese Subjects (SOS) trial – a prospective controlled intervention study of bariatric surgery
TLDR
Whereas high insulin and/or high glucose at baseline predicted favourable treatment effects, high baseline BMI did not, indicating that current selection criteria for bariatric surgery need to be revised.
The incidence of albuminuria after bariatric surgery and usual care in swedish obese subjects (SOS): a prospective controlled intervention trial
TLDR
Bariatric surgery is associated with reduced incidence of albuminuria compared with usual obesity care, and this study aims to determine the long-term effect of bariatric surgery on the incidence ofalbuminuria.
Cardiovascular risk after bariatric surgery for obesity.
Effects of Obesity Surgery on Overall and Disease-Specific Mortality in a 5-Country Population-Based Study.
TLDR
It is found that obese patients who have bariatric surgery have longer survival times than obese individuals who did not have Bariatric surgery, but their mortality is higher than that of the general population and increases with time.
Long-Term Effect of Bariatric Surgery on Liver Enzymes in the Swedish Obese Subjects (SOS) Study
TLDR
Compared to usual care, bariatric surgery was associated with lower serum ALT and AST levels at 2- and 10- year follow up and results in a sustained reduction in transaminase levels and a long-term benefit in obese individuals.
Gender effect on vascular inflammation following bariatric surgery.
TLDR
This is the first study that has demonstrated a gender difference in the inflammatory responses that may affect clinical outcome, and cardiovascular morbidity and mortality among obese men undergoing bariatric operation for weight loss.

Lifestyle, diabetes, and cardiovascular risk factors 10 years after bariatric surgery
TLDR
As compared with conventional therapy, bariatric surgery appears to be a viable option for the treatment of severe obesity, resulting in long-term weight loss, improved lifestyle, and, except for hypercholesterolemia, amelioration in risk factors that were elevated at baseline.

TLDR
Comparison of measurements with self-reported prevalence estimates revealed a considerable amount of previously undiagnosed hypertension and diabetes in the obese subjects, suggesting that the excess health risks associated with obesity may not be fully appreciated.
Long-term mortality after gastric bypass surgery.
TLDR
Long-term total mortality after gastric bypass surgery was significantly reduced, particularly deaths from diabetes, heart disease, and cancer, however, the rate of death from causes other than disease was higher in the surgery group than in the control group.

TLDR
There is no question that morbid obesity poses an increased risk to health and longevity, so it is only logical that substantial weight loss in this group of patients could be expected to improve both longevity and quality of life, provided that the treatment methods employed are free of serious side-effects.

TLDR
Studies lacking adequate control groups indicate that a sustained weight loss may induce a reduced mortality but results from controlled intervention studies are so far not available.

Surgical intervention as a strategy for treatment of obesity
TLDR
Surgical treatment for obesity needs to become much more common, particularly in obese patients with metabolic disturbances, particularly on the basis of weight loss and quality of life.
