What clinical obesity means
Clinical obesity describes excess adiposity significant enough to impair an animal’s health, function, or quality of life. It reframes obesity from a cosmetic or weight-only concern into a chronic medical condition that can be assessed, treated, and monitored.
The World Pet Obesity Association helps veterinary teams recognize, define, and manage obesity on clinical terms, with emphasis on long-term health, function, quality of life, and the people who care for these animals.
Clearer clinical language
Moving beyond weight alone toward a more clinically meaningful understanding of obesity.
Better assessment
Supporting consistent use of body condition, muscle condition, clinical history, and diagnostic findings.
Treatment-focused care
Emphasizing nutrition, monitoring, communication, long-term support, and evolving approaches to care.
