The Bariatric Surgery is performed almost exclusively through minimally invasive surgical access such as laparoscopy or highly minimally invasive and reversible procedures such as gastric banding and gastric bypass. But there are also irreversible surgeries such as vertical gastrectomy (sleeve gastrectomy) and bilio-pancreatic diversion with/without duodenal switch.

Each of these interventions affects weight loss and therefore also the resolution of co-morbidities with different effectiveness.

The decision to perform one rather than another is derived from the careful assessment of the type of obesity (gynoid/visceral), BMI, the patient’s eating habits, and thus the presence or absence of severe eating disorders, as well as the presence of associated conditions such as Type 2 Diabetes Mellitus.
