Resumo#### Summary points The relation between morbid obesity, serious morbidity, and early mortality is well known (fig 1⇓ and table 1⇓).1 2 A recent systematic review of over 890 000 participants found that each 5 point increase in body mass index (kg/m2) over 25 was associated with a 30% increase in overall mortality.3 Conservative approaches to managing obesity (dieting, exercise, and cognitive behavioural therapy) achieve long term weight loss in only a small minority of highly motivated individuals.4 Weight loss drugs such as orlistat and sibutramine produce modest weight loss and can be prescribed only for a short time.5 Bariatric (weight loss) surgery is the only treatment that randomised controlled trials have shown to produce effective long term weight loss.6 This review provides an overview of surgical procedures for adult obesity, including results, follow-up, and complications of surgery. It focuses mainly on practice in the United Kingdom. Fig 1 Proportion of people with a major comorbidity, by degree of obesity.

Data adapted from guidance from the National Institute for Health and Clinical Excellence1 Categories of obesity are classified according to body mass index (weight(kg)/(height (m)2)) (table 2⇓). Recommendations on the management of obesity in adults are provided in guidelines published by the National Institute for Health and Clinical Excellence (NICE).1 View this table: Table 2 Classification of obesity based on body …
