WHO Recommends Lifestyle Support Over Weight-Loss Drugs for Children Under 10

The World Health Organization (WHO) has issued its first global guidelines addressing childhood and adolescent obesity, emphasising healthy eating, physical activity and behavioural support over weight-loss medicines or surgery for children under 10.

The guidance, reported by Reuters on October 7, 2026, comes as childhood obesity remains a growing global public-health concern. The WHO said approximately 400 million people aged five to 19 were overweight in 2024, including around 170 million living with obesity. The prevalence of obesity in this age group has quadrupled since 1990.

The recommendations emphasise comprehensive, age-appropriate care rather than relying primarily on medication or surgical interventions.

What Does the WHO Recommend?

For children under 10, the WHO recommends approaches centred on healthy diets, physical activity and combined behavioural support. It advises against relying on obesity medicines, surgery or devices for this age group, citing uncertainty about safety and long-term effectiveness.

For adolescents aged 10 to 19 living with obesity, medication may be considered after supervised lifestyle interventions have failed. Bariatric surgery may be considered in selected adolescents with severe obesity who are physically and mentally mature, following six months of unsuccessful treatment.

These recommendations are clinical guidance, not a substitute for individual medical assessment. Treatment decisions must take account of the child’s health, development and circumstances.

Why Is the WHO Emphasising Lifestyle Support?

Children’s nutritional needs change as they grow. Weight management therefore requires attention to growth, development, mental well-being and the home and school environments in which children live.

The WHO recommends tailored dietary approaches, physical activity and behavioural programmes that involve caregivers. Supervised digital support may also be used as an additional option.

The organisation has highlighted uncertainty surrounding the long-term safety and effectiveness of GLP-1 medicines in younger populations. It has indicated that evidence may be reassessed as more research becomes available.

The guidelines do not suggest that medicines are never appropriate for adolescents. Instead, they recommend a more cautious, supervised approach.

The Global Childhood Obesity Challenge

According to the figures cited by the WHO, around 170 million people aged five to 19 were living with obesity in 2024. The increase in prevalence highlights the importance of prevention and access to appropriate care.

Childhood obesity is influenced by multiple factors, including diet, physical activity, family circumstances, the wider food environment and access to healthcare. Effective responses may therefore require action beyond the clinic.

Schools, families, communities and public-health systems can contribute by supporting nutritious food choices, opportunities for physical activity and access to appropriate professional guidance.

What Should Parents Do?

Parents concerned about a child’s weight should speak with a qualified healthcare professional rather than attempt restrictive diets or use weight-loss medicines without medical supervision.

Children need sufficient nutrition for growth. Care should focus on sustainable habits, emotional well-being and individual health needs rather than appearance or stigma.

Families can discuss practical changes with healthcare professionals, including regular physical activity, balanced meals, adequate sleep and supportive routines.

What the Guidelines Mean

The WHO’s recommendations reinforce the importance of comprehensive care for childhood obesity. They also underline that treatment must be appropriate to a child’s age and clinical circumstances.

The guidance does not eliminate the role of medication in every adolescent case. It places greater emphasis on evidence, supervision and sustainable lifestyle support while acknowledging that research into treatment options continues.
