The World Health Organization (WHO) has issued its first global guidelines for managing obesity in children and adolescents, calling for age-appropriate care that combines healthy eating, physical activity and behavioural support rather than relying on weight-loss medicines alone.
Released on October 7, 2026, the guidance aims to help health systems and healthcare professionals provide evidence-based care to children and young people living with obesity. It also highlights the importance of involving parents and caregivers and creating environments in which healthy food and regular physical activity are accessible.

Key Highlights
Important points readers should notice.
Issue/Event: WHO released its first global guidelines for managing obesity in children and adolescents.
Location: Global; the recommendations are intended to inform health systems and care worldwide.
Authority/Organisation: World Health Organization.
Action Taken: WHO recommended structured, age-appropriate interventions involving nutrition, physical activity and behaviour change, with specific limits and conditions for medical and surgical treatment.
Impact: The guidance gives healthcare professionals, parents and caregivers a framework for supporting children's physical and mental wellbeing while discouraging unsafe or unsupervised weight-loss approaches.
According to WHO estimates, approximately 170 million children and adolescents aged 5–19 were living with obesity in 2024. This included around 70 million children aged 5–9 and 100 million adolescents aged 10–19. The prevalence of obesity in this age group rose from 2% in 1990 to 8% in 2024.
The organisation also reported that about 400 million people aged 5–19 were overweight in 2024, including those living with obesity. Overweight and obesity are related but distinct classifications, and the figures should not be treated as interchangeable.
What Do the New Guidelines Recommend?
Editorial Analysis
Why This Matters
For parents: The guidance explains why sustainable routines and professional advice matter more than quick weight-loss solutions. For children: Respectful, supportive care can help protect physical health, confidence and emotional wellbeing. For schools: Nutritious food options, active play and anti-bullying measures can contribute to healthier environments. For healthcare providers: The recommendations offer an age-specific framework for assessing and managing childhood obesity. For policymakers: Prevention also requires access to affordable nutritious food, safe activity spaces and appropriate health services.
WHO recommends structured interventions addressing diet, physical activity and behaviour for children and adolescents living with obesity. These interventions may be delivered individually or combined into a broader programme suited to the child's circumstances.
The guidance recognises that childhood obesity is influenced by several interacting factors, including biological susceptibility, family and social environments, food availability, physical activity opportunities and broader living conditions. It is therefore not appropriate to treat a child's weight as simply a matter of willpower.
Parents and caregivers can support healthy routines by making nutritious meals accessible, encouraging enjoyable physical activity and helping children establish consistent sleep habits. These measures should focus on overall health and development rather than punishment or pressure to lose weight.
Are Weight-Loss Medicines Recommended for Children?
The recommendations distinguish between younger children and adolescents.
For children aged 0–9 years, WHO does not recommend pharmacological treatment, bariatric surgery or weight-management devices as treatments for obesity under the new guidance. Instead, the emphasis is on structured nutrition, physical activity and behavioural interventions.
For adolescents aged 10–19 years, approved medicines may be considered in selected cases when a supervised, comprehensive lifestyle programme has not achieved the desired results. Any such decision requires qualified clinical assessment and appropriate monitoring. Surgery is also limited to carefully selected adolescents with severe obesity under strict conditions.
These recommendations concern the management of obesity. They should not be interpreted as instructions to stop or change medicines prescribed for other medical conditions. Parents should discuss treatment decisions with a qualified healthcare professional.
Why Diet, Movement and Behaviour Matter
A child's daily routine can be shaped by the food available at home and school, opportunities to play or exercise, time spent sitting and sleeping patterns. These factors can influence health over time, but individual circumstances differ.
Families can begin with practical steps: offer a variety of nutritious foods, make water readily available, encourage active play suited to the child's age and abilities, and establish regular sleep routines. Changes are more likely to be sustainable when adults participate and the household environment supports them.
There is no single diet or activity plan suitable for every child. Children have different growth patterns, nutritional needs and medical circumstances. Restrictive diets, weight-loss supplements or unsupervised medicines should not be used as shortcuts.
Protecting Children's Mental Health
WHO's guidance also stresses the importance of addressing mental health alongside obesity. Children who experience weight-related teasing, discrimination or bullying may face emotional and social difficulties in addition to physical health concerns.
Parents, teachers and caregivers should avoid shaming children about their appearance or using humiliating language about body weight. Conversations about health should be respectful and age-appropriate, with an emphasis on wellbeing, energy, strength, sleep and healthy development.
Healthcare professionals can help families understand whether a child's growth pattern needs assessment and what support is appropriate. A child's weight alone does not provide a complete picture of health.
Why the Problem Goes Beyond the Household
WHO says the growing prevalence of obesity cannot be addressed through treatment alone. Access to affordable nutritious food, safe places for physical activity, supportive schools and effective healthcare services also matters.
Schools and communities can help by supporting nutritious food choices, opportunities for movement and anti-bullying practices. Policymakers can contribute through measures affecting food environments, education, urban planning and access to healthcare.
The new guidelines provide a framework for care, but their impact will depend on how health systems and communities put the recommendations into practice.
