Increasing clinical awareness of obesity as a serious, chronic, relapsing, and treatable disease

The American Medical Association recognized obesity as a disease in 2013. Obesity is influenced by genetic, environmental, physiologic, behavioral, and sleep factors and is associated with approximately 200 health conditions. Assessed using body mass index, body composition, and evaluation of weight-related complications, obesity is treated with lifestyle interventions, anti-obesity medications, and metabolic and bariatric surgery. The age-adjusted prevalence of overweight and obesity in US adults has increased substantially in the 21st century, from an estimated 56% in 1988-1994 to approximately 73.1% in 2017-2018. Nevertheless, there are substantial barriers to successful obesity treatment in the United States, including inadequate treatment coverage; a lack of acceptance by providers, patients, and employers that obesity is a disease; the perception that treatment is ineffective; and the belief that obesity is a behavioral concern related to a lack of willpower. Obesity is a serious, chronic, relapsing, and treatable disease associated with many related conditions; it requires long-term medical management and multimodal care strategies.
