Adolescent Bariatric Surgery

Severe obesity is a serious medical problem that can affect the health and wellbeing of children and adolescents. For young people with severe obesity who are unable to achieve or maintain adequate weight loss with conventional approaches, bariatric (weight loss) surgery may offer the best opportunity for successful and lasting weight reduction.

At the NewYork-Presbyterian Morgan Stanley Children’s Hospital Center for Adolescent Bariatric Surgery and the NewYork Presbyterian Komansky Children’s Hospital Bariatric Surgery Program, multidisciplinary teams of weight loss specialists provide bariatric surgery as part of a comprehensive, long-term weight management program for pediatric patients with severe obesity. These centers are among only a handful in the U.S. approved to offer weight loss surgery to young patients. Our experts in pediatric gastroenterology, surgery, endocrinology, nutrition, mental health, and other specialties work together to help children and adolescents achieve and maintain their weight loss for health and quality of life.

More top pediatric specialists than any other hospital in New York.

The American College of Surgeons has accredited NewYork-Presbyterian Morgan Stanley Children’s Hospital as an Adolescent Center for bariatric surgery with the highest possible designation – the first program to be so named in New York State and one of only six nationwide. NewYork-Presbyterian/Weill Cornell Medical Center is accredited as a Comprehensive Center with Adolescent Qualifications.

Obesity and Health Risks

Obesity is an excess of body fat, which is defined as a body mass index (BMI) above 30. Severe obesity is generally defined as being at or above 120% of the 95th percentile for age-adjusted BMI on their growth chart. Children with obesity are more likely to be obese as adults, and obese adults have a higher risk for developing metabolic disorders including type 2 diabetes, high blood pressure, sleep apnea syndrome, and high cholesterol and triglycerides.

Bariatric surgery has been shown to reverse or dramatically improve many of these comorbidities.

About Our Program

At NewYork-Presbyterian’s two adolescent bariatric surgery centers, located at NewYork-Presbyterian Morgan Stanley Children’s Hospital and NewYork Presbyterian Komansky Children’s Hospital, multidisciplinary teams of weight management specialists provide comprehensive care to adolescents with severe obesity. Candidates for surgery typically have a BMI greater than 40, or a BMI greater than 35 with obesity-related medical conditions. Together the Centers have provided metabolic and bariatric surgical care to over 500 children and adolescents since 2005.

Young patients come to our centers in some cases already diagnosed with insulin resistance, hypertension, irregular periods, fatty liver disease, high cholesterol levels, or other conditions associated with their obesity. These patients undergo rigorous education and a lengthy program of multidisciplinary evaluation to determine whether bariatric surgery is appropriate for them.

Our multidisciplinary weight management teams include experts in pediatric gastroenterology, surgery, endocrinology, nutrition, mental health, and other specialties. Together, we evaluate your child and customize an effective plan of long-term, personalized care that includes surgery, education, follow-up, and support as your child settles into new routines and habits that encourage lasting weight loss.

Our programs provide the following:

  • Health and metabolic screening
  • Nutritional guidance, dietary management, and education
  • Individualized exercise programs
  • Laparoscopic weight loss surgery
  • Ongoing follow-up and support

Evaluating Adolescents for Bariatric Surgery

As noted above, adolescent patients must have a BMI greater than 40 or a BMI- greater than 35 with significant associated illnesses or their growth chart equivalents. Not every adolescent, however, is considered a good candidate for weight loss surgery. Since successful weight loss mainly depends on changing eating behavior and activity patterns, our multidisciplinary team evaluates patients monthly for a minimum of six months before scheduling a weight-loss operation. The team looks for patients to make healthy changes in their eating habits, omitting high-calorie drinks and minimizing high-calorie snacks as well as increasing activity. Candidates who meet standard ASMBS pediatric and metabolic surgery guideline criteria and show positive changes in eating and exercise habits may then be offered weight loss surgery.

Types of Bariatric Surgery For Adolescents

We currently offer the following type of laparoscopic bariatric surgery to our adolescent patients:

  • Laparoscopic sleeve gastrectomy, a procedure for surgical weight loss whereby approximately 80% of the stomach is removed, dramatically reducing the patient's capacity for food intake. This procedure is performed laparoscopically through five small incisions. This surgery has some effect on the body’s absorption of nutrients, and appropriate intake of protein and vitamins after surgery is important.

Long Term Follow-Up

Obesity is a chronic disease, and successful treatment requires long-term follow-up. We continue to follow all patients post-operatively to provide care and to collect results so that others contemplating weight loss surgery can make informed decisions.

Seminars and Support Groups

NewYork-Presbyterian/Columbia University Irving Medical Center’s Center for Metabolic and Weight Loss Surgery offers seminars and support groups to provide adolescent patients with valuable knowledge and comfort before, during, and after bariatric surgery.
