Obesity is a chronic disease in which someone has so much extra fat that it negatively impacts his or her health. Over 60 percent of American adults weigh more than is healthy. AGA understands the importance of embracing obesity as a chronic, relapsing disease, and supports a multidisciplinary approach to the management of obesity.


Providing Value-Based Management of Patients with Obesity

GIs are uniquely positioned to lead a care team to help patients with obesity achieve a healthy weight. The AGA Obesity Practice Guide was created to provide a comprehensive, multi-disciplinary process to personalize innovative obesity care for safe and effective weight management. 

An important part of implementing the AGA Obesity Practice Guide is understanding how to integrate and operationalize obesity management in your practice for financial success. AGA created a series of webinars to provide guidance to help you assess your ability to participate in and implement an obesity program. Watch the webinars in the AGA Community at the links below (login required). 

Obesity Practice Guide

The POWER (Practice guide on Obesity and Weight management, Education and Resources) white paper provides physicians with a comprehensive, multi-disciplinary process to guide and personalize innovative obesity care for safe and effective weight management.

Instead of a linear care pathway, the POWER program care cycle is circular in order to represent the fact that obesity is a chronic disease that requires a lifelong multidisciplinary approach for effective, long-term therapy. Each portion of the circle represents a different step in the continued, comprehensive approach to obesity treatment.

The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), The Obesity Society (TOS), and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) contributed content to the POWER program, which was endorsed with input by the American Society for Gastrointestinal Endoscopy (ASGE), American Society for Metabolic and Bariatric Surgery (ASMBS), American Association for the Study of Liver Diseases (AASLD), Obesity Medicine Association (OMA) and Academy of Nutrition and Dietetics (AND).
