Have there been any updates to the 1991 NIH surgical indication criteria?
There have not been any NIH updates; however, there has been a trend in extending surgical criteria to those with BMIs less than 35. The International Diabetes Federation added to their position statement in 2011 that bariatric surgery should be considered for those with poorly controlled type 2 DM and BMI 30 or more. The FDA in 2011 added approval for gastric banding for individuals with a BMI of 30 or more provided a serious comorbidity exists.
