title: Filling the treatment gap in the weight management of overweight and obese patients.
abstract: Approximately two out of three adult Americans are overweight or obese. Despite widespread recognition of this disorder, there has been little progress in the past 20 years in finding effective noninvasive treatments for weight loss. The consequences of obesity are increasingly well recognized and include increases in blood pressure, plasma lipids, the onset of type 2 diabetes, sleep apnea, asthma, osteoarthritis and a variety of cancers. Obesity can increase the rate of pregnancy complications and fetal malformations in normoglycemic women. Current medical approaches to obesity, including intensive lifestyle interventions and drug therapies, have been successful in achieving modest weight loss of 4-7%, less than the 1998 NIH Guidelines target of 10%. Surgical approaches, including laparoscopic adjustable gastric banding, vertical banded gastroplasty and Roux-en-Y gastric bypass, are much more successful, achieving weight loss of 15-50%. A treatment gap therefore exists in the management of obese and overweight patients, because many patients desire and would receive great health benefits by achieving weight loss of 7-15%. This review will discuss the dilemma of the treatment gap and explore possible ways by which it may be filled in the future by the use of innovative approaches.
