Bariatric Surgery

Here for Every Step of the Journey to a Healthy Weight

Bariatric Surgery

The bariatric surgery program at Nationwide Children's was the first free-standing adolescent bariatric surgery center in the U.S. to be accredited by the American College of Surgeons Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP). This recognition certifies that the highest standards of quality and safety are being met at our center, and our staff and facilities are 100% equipped to meet the needs of our bariatric patients.

Nationwide Children's is also one of only five institutions nationally to join a multi-institution clinical research study to understand the benefits and risks of bariatric surgery in adolescents.


The Bariatric Surgery Program has achieved MBSAQIP accreditation.

About the Bariatric Surgery Program

Nationwide Children’s Hospital is one of America’s largest health care and research centers focusing on children and teens. We care for more than one million patient visits each year. Families travel from around the country and even the world for our care. Our doctors and researchers work to advance children’s health care.

Our Center for Healthy Weight and Nutrition involves prevention, teaching, research, medical and bariatric weight management. We offer two bariatric surgery options for teens. These include gastric bypass and gastric sleeve.

Nationwide Children’s is also one of only five hospitals in the country taking part in a research study to better understand the benefits and risks of bariatric surgery in teens.

Who Qualifies for Weight Loss Surgery? 

We understand that weight loss surgery is not for all overweight people. It offers an option for people who have not been able to maintain weight loss and control their health through dieting alone. To qualify for weight loss surgery, patients must:

  • Be at least 100 pounds over their ideal body weight (BMI greater than 40 kg/M2 or BMI greater than 35 kg/M2 with medical problems)
  • Complete the work up for bariatric surgery, including our online information session.
  • Be recommended for bariatric surgery by our bariatric team

Transition of Care

We work closely with our patients and their family to smoothly transition to a bariatric center focused on adult patients when and if it becomes necessary. Nationwide Children's Hospital is a major pediatric affiliate of The Wexner Medical Center at The Ohio State University, College of Medicine.

What Options are Available? 

At Nationwide Children’s, we offer two types of bariatric surgery: Gastric Bypass Surgery and Gastric Sleeve Surgery. Both of these surgeries cause restriction in the amount of food that can be eaten at one time, so patients feel full faster. The weight loss for any surgery depends on how well patients follow the recommended nutrition and exercise program.

Gastric Sleeve Surgery

Gastric Sleeve Surgery (Sleeve Gastrectomy)

After gastric sleeve surgery, food will travel down your throat and enter the tube-like sleeve created by removing 80% of your stomach and stapling closed the rest of the stomach.

Gastric Bypass Surgery

Gastric Bypass Surgery

With gastric bypass surgery, a small pouch is created by stapling closed the top portion of the stomach, separating it from the lower portion.
