Obesity and body-image concerns in adolescents
Also known as Adolescent obesity · Teenage overweight and obesity · Body image disturbance in adolescence · Weight-related distress · Disordered eating in higher-weight adolescents · Paediatric metabolic syndrome · Severe obesity in adolescence
A fellowship approach to adolescent obesity and body-image concerns: BMI-based classification with adult crossover, multifactorial aetiology, comorbidity screening, staged and weight-neutral lifestyle-to-surgery management, and concurrent mental-health and body-image care that refuses to reduce a young person to a number on the scale.

A 15-year-old walks into your clinic. Her BMI plots above the 97th percentile, her mother is anxious, and she will not make eye contact. Three things are true at once, and a good clinician holds all of them: she has a chronic metabolic disease that can be staged and treated, she carries a psychological burden that may dwarf the physical one, and the words you choose in the next ten minutes will either build trust or shut it down. This page teaches you to hold all three — to classify, screen for comorbidity, screen for distress, and deliver staged care that refuses to reduce her to a weight. [1] [8]
Overview & Definition
Obesity in adolescence is best understood first as a patient, then as a number. The young person in front of you has a chronic, relapsing disease of excess adiposity in which biological, behavioural, psychosocial and environmental forces have pushed energy balance toward sustained fat storage. The 2023 American Academy of Pediatrics Clinical Practice Guideline reframes it this way deliberately, to move the conversation away from blame and toward long-term, treatable disease. [1]
Clinically you define the physical dimension with body mass index plotted against age and sex on a growth reference. Obesity is a BMI at or above the 95th percentile for age and sex from ages 2 through 19, and severe obesity carries stricter thresholds that change management. The Endocrine Society guideline sits alongside the AAP framework and gives the same percentile-based definition. [1] [2]
Running alongside the physical disease is a psychological dimension — body-image concern. This is the gap between the body a young person perceives and the body they feel they ought to have, amplified by peers, family, media and clinicians. Body-image concern ranges from a healthy, accepting relationship with one's body through mild dissatisfaction to clinically significant disordered eating. Crucially, distress does not map neatly onto BMI: a young person in a larger body can feel fine, and a young person in a slim body can be devastated. [8] [11]
The headline numbers matter, but they exist to orient you, not to summarise a person. The tracking figure tells you why adolescence is a strategic window: intervention here changes the adult trajectory. [5] [8]
