Bariatric Surgery :: Nationwide Children's Hospital

Bariatric Surgery

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
  • Be recommended for bariatric surgery by our bariatric team

Bariatric Surgery requires major lifestyle changes

To maintain weight loss after surgery, you will still have to exercise and limit food amounts. You will also need to change the types of food that you eat every day. It is important to remember that bariatric surgery is only a tool to support you in achieving lasting weight loss. Healthy eating patterns and regular exercise are the keys to success.

How much weight will you lose?

On average, people steadily lose one to two pounds per week. This means you will lose 50-100 pounds or more in a year. The amount of weight loss and the ability to keep it off depends on how well you follow the diet and exercise program after weight loss surgery.

It’s a long process

Leading up to surgery, a complete evaluation is needed. This includes a physical exam, nutrition, activity and social work evaluations, psychological testing, evaluation by other specialists and other medical tests. This process can take 6-12 months and requires your full participation at each step. Patients will have regular visits before surgery, during the first 12 months after bariatric surgery and then every 6 months for years to come. Patients are required to attend at least two support group sessions before surgery and at least one after surgery.

Weight Loss Surgery Options

At Nationwide Children’s Hospital, we offer three types of bariatric surgery: Gastric Bypass, Gastric Sleeve, and Laparoscopic Adjustable Band (currently, based on FDA regulations, you must be at least 18 years old to have laparoscopic adjustable band surgery). All 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.

Laparoscopic Surgery vs. Open Surgery

Most patients are candidates for laparoscopic bariatric surgery. In this type of surgery, several small incisions are made in the stomach, through which small, thin instruments, including a telescope and camera, are inserted. The camera and telescope send pictures of the internal organs and surgical instruments onto a TV screen. Laparoscopic surgery reduces the pain and complications after surgery, since the incisions are so small.

For medical reasons, some patients may need an open surgery. If this is needed, the surgeon makes one large incision in the stomach to access the organs. The surgeon will explain each type of surgery and determine which type of surgery is best for you.

Teen Bariatric Surgery is a Commitment

In a May 2011 article, "Surgery Is No Quick Fix for Obese Teens," Dr. Marc Michalsky explains teen weight loss surgery is not a cosmetic procedure and is generally not performed on teens until they have gone through puberty. The article also follows patients and discusses their outcomes along with how life is changed after bariatric surgery.
