Modern understanding and advances in the diagnosis and treatment of obesity

As a multifactorial chronic metabolic disorder with complex causes and serious health risks, obesity has drawn significant societal and medical attention. This article systematically reviewed the latest advancements in the clinical diagnosis and treatment of obesity. A disease-centered diagnosis and treatment concept has been proposed, which combines BMI and introduces a brand-new clinical diagnosis and treatment standard centered on fat content and functional disorders, such as new diagnostic markers like adipose tissue distribution, visceral adiposity, and waist-to-height ratio, to conduct a comprehensive assessment and lifespan management of patients. In recent years, novel biomarkers and artificial intelligence (AI)-assisted diagnosis have provided new tools for the diagnosis and treatment of obesity. In terms of treatment, combined therapy based on lifestyle and behavioral intervention has been widely recognized. The advent of new weight-loss drugs, such as glucagon-like peptide-1(GLP-1), minimally invasive techniques such as endoscopic sleeve gastrectomy(ESG), which reduced surgical risks, have provided possibilities for the treatment of obesity. The current concept of obesity management has become increasingly mature, feasible, and standardized. The construction principles of a weight management center, characterized by centralized management and individualized treatment, ensure the long-term stability of body weight and promote a healthy quality of life for patients with obesity.
