  • Candidates Must Be Considered Morbidly Obese: This means that the candidate has a body mass index (BMI) of 35 or higher with serious health problems that are related to their obesity, such as Sleep Apnea, Hypertension (High Blood Pressure), type 2 Diabetes, and many more. Individuals suffering from morbid obesity are at risk for more than 30 co-morbid medical problems such as these. If a candidate’s BMI is 40 or greater he/she is considered a surgical candidate even without associated medical conditions because the risk of serious medical problems is so high.

  • Candidates Must Be Willing and Motivated to Make the Permanent Lifestyle Changes Necessary to Live a Healthier Life: Laparoscopic Roux-en-Y Gastric Bypass is not a quick-fix for obesity. Rather, it is a starting point toward a healthier lifestyle.
