2015 ASGE立场声明：内窥镜减肥手术在临床中的应用

The prevalence of obesity (body mass index [BMI] of 30 kg/m2) in adults in the United States remains high at 35%. Although the total number of U.S. adults with a BMI of 30 kg/m2 has remained stable since 2003, the prevalence of adults with a BMI >40 kg/m2 increased 70% between 2000 and 2010. This is of particular concern due to the positive correlation between increasing BMI above >30 kg/m2 with rates of obesityrelated comorbidities and mortality.5-7 The estimated cost associated with treating obesity and directly attributable diseases ranges from $147 billion to $210 billion, which accounts for up to 21% of U.S. health expenditures. However, weight loss can lead to improvements in obesity-related morbidity and mortality, with a positive correlation between the amount of weight loss and improvement in obesity-related disease.
