ReviewBariatric surgery: mechanisms, indications and outcomes.
The rising problem of obesity is causing major health problems, reduced quality of life and reduced life expectancy. It now generates approximately 10% of all health costs. The progression of the problem indicates preventive measures have been unsuccessful so far. ⋯ Perioperative risk is significant with gastric bypass and late revisional procedures can be required after both procedures. Gastric banding is indicated in any adult who has a BMI over 30, has problems with their obesity and has made substantial effort to reduce their weight by lifestyle methods. Gastric bypass or biliopancreatic diversion should be considered in those with BMI greater than 35 if banding is contraindicated or has been unsuccessful.
