For the purpose of these guidelines, people are defined as having morbid obesity if they have a body mass index (BMI) either equal to or greater than 40 kg/m2 or greater than 35 kg/ m2 in the presence of significant co-morbid conditions that could be improved by weight loss. With the availability of minimally invasive techniques, there is a potential for the patient to consider this type of surgery as minor. It is incumbent upon the bariatric surgeon to warn the patient of the potential benefits and longer term implications of surgery as well as the associated risks, including serious complications and postoperative mortality.
