In a recent study researchers proposed a new scientifically correct and medically actionable disease classification system for obesity based on the concept of Adiposity-Based Chronic Disease (ABCD). Diagnostic term Adiposity-Based Chronic Disease (ABCD) reflects both the pathophysiology and clinical impact of obesity as a chronic disease. The research published online in Obesity is the flagship journal of The Obesity Society. The proposed coding system has four domains: pathophysiology, body mass index (BMI) classification, complications, and complication severity; and incorporates disease staging, specific complications that impact health, the basis for clinical intervention, individualized treatment goals and a personalized medicine approach. The American Association of Clinical Endocrinologists (AACE) and the European Association for the Study of Obesity (EASO) have both embraced the concept of ABCD.
