Clinical Obesity: A Classic Endocrinology Critique.
Obesity is a ‘heavyweight’ disease, with more than its fair share of controversies and challenges. Differing modes of diagnosis, a variety of diagnostic and interventional thresholds, and a rapidly evolving therapeutic landscape all contribute to confusion in obesity medicine. To bring clarity to this field, the term ‘clinical obesity’ has recently been proposed [Box 1]. The Lancet Commission on obesity as a condition characterized by excessive adiposity, along with at least one of 18 complications mentioned in adults, or one of 13 complications identified in adolescents.[1] While these lists are exhaustive, they are unable to encapsulate the entire spectrum of life with obesity.Box 1: Definition of clinical obesityWe therefore suggest a fresh look at this concept. We define clinical obesity as a disease state characterized by excessive adiposity, identified by ethnic age and gender specific anthropometric and/or imaging parameters, associated with any comorbid condition, complication or clinically significant laboratory abnormality/disease, dysfunction, disability, or deviation from normal, which has the potential to be corrected by weight loss and maintenance. This definition includes the Lancet rubric, and goes beyond it. It focuses on action (weight loss) to achieve better health (potential to be corrected). It is also more inclusive, as it makes the divide between comorbidity and complication irrelevant. By including ‘disease, dysfunction, disability and deviation from normal’, it covers every possible aspect of obesity medicine. The biopsychosocial challenges of living with obesity all find a place under this umbrella definition.[2] This person-friendly definition contrasts with contemporary thought, which has excluded psychological and social facets of obesity from the concept of clinical obesity.[3] This is unfortunate, and these issues are major impediments to quality of life with obesity.[4] While we commend the Commission for its attempt to standardize obesity, we highlight the need for a more inclusive, more person-centred definition, that addresses psychosocial and endocrine health as well.
