A working paradigm for the treatment of obesity in gastrointestinal practice.

Obesity is a chronic, relapsing, multi-factorial disease characterized by abnormal or excessive adipose tissue accumulation that may impair health and increase disease risks. Despite the ever-increasing prevalence and economic and societal burden, the current approaches to treat obesity are not standardized or generally effective. In this manuscript, we describe a current working paradigm developed by a consensus approach for the multidisciplinary treatment of obesity in the GI practice. Obesity should be managed as a continuum of care focusing on weight loss, weight loss maintenance and prevention of weight regain. This approach needs to be disseminated throughout the health care system, coordinated by a multidisciplinary team and include gastroenterologists who are in a unique position to address obesity. Gastroenterologists are in the front line of managing the morbidity resulting from obesity, and have expertise in use of the essential tools to manage obesity: nutrition, pharmacology, endoscopy and surgery.
