Bariatric Surgery Requirements

University Hospitals Digestive Health Institute’s Nutritional Health & Bariatric Surgery Center uses the National Institutes of Health guidelines in determining if patients are good candidates for weight loss surgery.

Body Mass Index and How It Is Used

Body mass index (BMI) is the primary measurement used to determine a patient’s eligibility for weight loss surgery. BMI is a number that is calculated from a patient’s height and weight; as a person’s body mass increases, their risk of weight-related diseases increase as well.

To qualify for weight loss surgery, patients must meet one of the following criteria:

  • BMI of 40 or higher (about 100 pounds overweight)
  • BMI of 35-39.9 and at least one medical condition caused by being overweight. These conditions include: diabetes, high blood pressure, sleep apnea and many more

To qualify for endoscopic weight loss procedures, patients must have a body mass index greater than 30.

Weight Loss History

Weight loss procedures are an option for patients who have not succeeded at diets and other weight loss efforts. The Nutritional Health & Bariatric Surgery Center requires that patients have tried other weight loss measures in the past.

Lifestyle Changes for Lifelong Success

Each patient who has weight loss surgery must commit to lifelong changes. These include:

  • Following a healthy diet
  • Exercising regularly
  • Taking vitamin and mineral supplements as directed
  • Following up with the bariatric program
