170 million children, and a first global rulebook that does not start with a drug
What happened
On 7 October 2026 the World Health Organization published its first ever global guidelines on treating obesity in children and young people. There are two documents. One covers children. One covers adolescents aged 10 to 19. Until now, WHO had clinical advice for adults with obesity but no matching advice for the young. That gap has been filled. The numbers behind the guidelines are large. WHO says that in 2024, 170 million children and adolescents aged 5 to 19 were living with obesity. About 70 million of them were aged 5 to 9. About 100 million were aged 10 to 19. Across that whole age group, obesity has quadrupled since 1990, rising from 2% to 8%. The headline recommendation is not what many people might expect. WHO strongly recommends structured support with diet, physical activity and behaviour change, given one-to-one or as part of a wider programme. Dr Luz Maria De Regil, Director of WHO's Department of Nutrition and Food Safety, put it plainly: "The foundation of obesity care for children and adolescents is not medicine or surgery".
Why this matters
Obesity in childhood is often treated as a matter of willpower. These guidelines treat it as a health condition that deserves proper care, and they say what that care should look like. That matters for families who have been offered very little. It also matters for families who have been offered a lot of advice but no real support. A leaflet is not a programme. There is a second reason this is important. Weight-loss injections and tablets are now widely talked about, including for teenagers. WHO has set out where medicines fit, and where they do not. That gives parents, GPs and paediatricians a shared reference point instead of a guessing game. WHO also makes a point about mental health. It says health workers should deal with obesity and mental health conditions early and together, rather than one after the other. Children living with obesity often face bullying and low mood. Treating the weight and ignoring the distress helps nobody.
What the evidence actually says
The guidelines are graded, which means WHO says how confident it is in each point. That detail is worth reading carefully. Strongly recommended: structured dietary, physical activity and behaviour-change support, delivered on its own or as part of a multimodal programme. This is the core of care. Conditionally recommended: digital health tools, such as apps, but with a parent or carer supervising. A conditional recommendation means the evidence is weaker and the decision should fit the child and family. For children aged 0 to 9, WHO does not recommend medicines, weight-loss surgery or weight-loss devices. For adolescents aged 10 to 19, approved medicines may be considered, but only where a supervised multimodal lifestyle programme has not achieved the results hoped for. Medicines are a step after support, not instead of it. For adolescents with severe obesity, bariatric surgery may be considered under strict conditions. WHO also says care should go beyond weight loss alone. It should be person-centred, suitable for the child's age and stage, and include long-term follow-up. Weight is one measure. Health, function and how a young person feels all count too. Finally, WHO is clear that clinical care cannot carry this on its own. It calls for healthy food and physical activity to be made cheaper and easier to reach, including through regulation and tax measures, and for action across education, urban planning, transport and social protection.
Qurexa perspective
Most of what WHO recommends happens in homes, schools and clinics, not in a pharmacy. But one part does touch what we do. Where a young person is prescribed an approved weight-management medicine, WHO is explicit that it sits on top of a supervised programme and needs long-term follow-up. Long-term only works if the medicine actually arrives, month after month, and if someone is on hand to answer questions about it. That is the part we help with: getting prescriptions delivered reliably to Lincolnshire homes, and making it easy to ask a pharmacist something you did not want to ask in a busy waiting room. We would rather a family asked us a small question early than skipped a dose and said nothing.
Practical advice
If you are worried about your child's weight, these guidelines suggest a few sensible steps. Start with your GP or school nurse, not a search engine. Ask what structured support exists locally. WHO's strongest recommendation is for a programme, so it is fair to ask for one. Ask for the whole picture to be looked at. That includes sleep, mood, bullying and any other health conditions. WHO says mental health should be addressed at the same time, not later. If an app is suggested, stay involved. WHO only recommends digital tools with a parent or carer supervising. If medicines come up for a teenager, ask two questions. Has a supervised programme been tried? And what is the follow-up plan? Those are the conditions WHO sets out. Be wary of anything sold online that promises fast results for children. WHO does not recommend medicines, surgery or weight-loss devices for children aged 0 to 9 at all. And keep it kind. The guidelines are built around support, not blame.
What to know
WHO has published its first global guidelines on obesity in children and adolescents, on 7 October 2026. In 2024, 170 million children and adolescents aged 5 to 19 were living with obesity, four times the share seen in 1990. Structured diet, activity and behaviour support is strongly recommended as the foundation of care. Digital tools are conditionally recommended with adult supervision. Medicines, surgery and weight-loss devices are not recommended for children aged 0 to 9. For adolescents, approved medicines may be considered only after a supervised programme has not worked, and surgery only in severe cases under strict conditions. Mental health should be handled alongside weight, and care should include long-term follow-up.
