Although obesity affects more than 1 billion people worldwide, according to a global analysis published in The Lancet, it still lacks a clear “identity” in research, social perception, and the healthcare sector. This lack of clarity hinders accurate diagnoses and treatments, while also perpetuating stigma and prejudice. Specialists argue that obesity is a chronic disease rather than just a condition that leads to other diseases.
At the latest International Congress on Obesity held in São Paulo, Brazil from June 26 to 29, The Lancet Commission on the Definition and Diagnosis of Clinical Obesity announced that it is conducting a global study to create a clear definition for obesity. This condition is often wrongly associated solely with individual choices. Ricardo Cohen, MD, PhD, coordinator of the Obesity and Diabetes Specialized Center at the Oswaldo Cruz German Hospital, São Paulo, and a key researcher in the study, made the announcement. “The current definition of obesity is too broad and ineffective for our needs,” said Dr. Cohen.
Dr. Cohen highlighted several challenges stemming from the lack of a precise definition, including confusion between prevention and treatment strategies, inadequate access to evidence-based treatments, and misconceptions about obesity and its reversibility. He also pointed out the limited understanding of the metabolic and biological complexity of the disease. “Society is comfortable with the current scenario because people are commonly blamed for their obesity. This is evident in the acceptance of so-called ‘magic solutions,’ such as fad diets, and the idea that obesity is merely a result of overeating and underexercising,” he said, noting the mental health damage that this perception can cause.
The difficulty in defining obesity stems from its common classification as a risk factor rather than a disease, said Dr. Cohen. Obesity meets the criteria to be considered a disease, such as well-defined pathophysiologic and etiologic mechanisms. In this way, obesity resembles diabetes and depressive disorders, which are classified as diseases based on the same criteria. This inconsistency, maintained by societal perceptions and the healthcare sector, creates confusion. Many professionals still lack a clear understanding of obesity as a disease.
This confusion perpetuates stigma and ignores the unique metabolic function in individuals. As a result, treatments often focus on preventing secondary diseases like diabetes and hypertension rather than on addressing obesity itself. Dr. Cohen recounted the case of a patient with fatigue, knee pain, and osteolysis who couldn’t perform daily activities but did not receive the necessary care. “If he had diabetes, he could have access to treatment because diabetes is recognized as a disease and needs to be treated. But since obesity is not recognized as such, he was sent home.”
To address these challenges, The Lancet Commission’s study, which is expected to be published this year, aims to establish clear diagnostic criteria for adults and children. Drawing inspiration from medical disciplines with well-established diagnostic criteria, such as rheumatology and psychiatry, the research has defined 18 criteria for adults and 14 for children.
The study also redefines treatment outcomes, sets standards for clinical remission of obesity, and proposes clear recommendations for clinical practice and public health policies. The ultimate goal, according to Dr. Cohen, is to transform the global treatment spectrum of obesity and improve access to necessary care.
“Our plan is to recognize obesity as a disease so that health policies, societal attitudes, and treatments will address it more effectively. This approach will also help reduce the harm caused by stigma and prejudice,” concluded Dr. Cohen.
