The increasing prevalence and far-reaching medical, social, and economical implications of obesity have made it a national health-care crisis in the United States.
About one in every three persons is at least 20% above « ideal » body weight, and approximately 5% have direct weight-related serious health problems (morbid obesity), including hypertension, hyperlipidemia, coronary artery disease, adult-onset diabetes mellitus, degenerative osteoarthropathy, and obstructive sleep apnea.
Morbidly obese patients have an estimated 6-to 12-fold increase in mortality.
In addition, they have a substantially diminished quality of life, not only physically but also psychosocially due to overt and occult prejudice.
Weight reduction must be aggressively pursued in these patients.
Medically supervised weight-control programs have been ineffective because patients cannot maintain pronounced long-term weight loss.
In contrast, current operative methods have been proved to be effective in helping patients achieve and maintain permanent weight reduction.
Several operations have been designed and assessed ; with these procedures, weight loss is achieved by inducing malabsorption, maldigestion, early satiety, or a combination of these outcomes.
Although these operations have associated side effects and limitations, the expected benefits outweigh the risks.
For optimal results, patients must be carefully selected and treated by a multidisciplinary group.
