title: Obesity surgery: a gastroenterologist's perspective.
abstract: Obesity is increasing at an alarming rate. Approximately 25% of adult women and 20% of adult men in the United States are obese. Obesity is increasing even more rapidly in children. The incidence of type 2 diabetes mellitus, hypertension, dyslipidemia, and liver disease is significantly increased in obese persons. Traditional methods of diet, exercise, drugs, and behavior modification are unsuccessful in the treatment of patients who are morbidly obese and have a body mass index of 40 kg/m(2) or a body mass index of 35 kg/m(2) with comorbidity. Multiple surgical alternatives to the traditional treatments are available and have been successful. Considerable weight loss may be achieved and maintained. Each procedure is associated with a variety of side effects and complications. The selection of patients for bariatric surgery requires a careful evaluation of their medical condition in addition to multiple psychological and social factors. Postoperative care entails careful medical follow-up and long-term support. Patients may have a difficult time adjusting to their new ability to eat normally.
