Bariatric surgery for children is currently recommended primarily for those who either have a BMI of 35 or above and have major health problems related to their obesity, and for children with a BMI of 40 or above who are showing early signs of obesity-related health problems, Inge said.
Not every child meeting those criteria would be a good candidate for weight-loss surgery, however.
Because bariatric surgery can deplete the body of key nutrients needed for healthy development, children should have already undergone the majority of their linear growth, said Dr. Lori Laffel, chief of the pediatric, adolescent and young adult section at the Joslin Diabetes Center and an associate professor of pediatrics at Harvard Medical School.
