Weight loss surgery for morbidly obese adolescents: a review

Obesity is common among adolescents resulting in substantial comorbidities and reduced life expectancy. Conservative treatments normally fail to ensure significant and sustained weight loss and suitable adolescents should be offered weight loss surgery. Laparoscopic Adjustable Gastric Banding and Roux-en-Y Gastric Bypass are commonly used in adolescents. Complications in RYGB tend to be more severe, but the procedure leads to more immediate results. LAGB complications are often device-related and less severe. Dietary adherence, eating behaviour and unrealistic patient expectations often cause problems. Significant and sustained weight loss of 50-70 per cent of excess weight is achievable, comorbidities and psychological problems improve. Meticulous patient selection and preparation and good post-operative care are vital for successful weight loss surgery. Weight loss surgery is safe, effective and economically viable with nurses playing a vital role at all stages of its application.
