The generally accepted criteria are a body mass index of 40 or above, or a BMI between 35 and 40 together with a related condition such as type 2 diabetes, hypertension or sleep apnoea. These numbers alone do not decide the matter; age, eating habits, previous weight-loss attempts and overall health are assessed together. Before surgery a multidisciplinary preparation process is carried out involving endocrinology, psychiatry and nutrition specialists.

For bariatric and cancer operations the hospital stay is a few days and full recovery takes a few weeks. Compared with open surgery, the keyhole approach means less pain, a shorter hospital stay and smaller scars.
