What happened

On Oct. 7, the World Health Organization released its first global guidelines on managing obesity in children and teens. It puts diet, physical activity and behavior-change programs first. It advises against weight-loss drugs, bariatric surgery or devices for children under 10. For ages 10 to 19, drugs such as GLP-1s may be considered only after supervised lifestyle programs fail.

Summary

The World Health Organization has issued its first global guidelines for treating obesity in children and teenagers. The core message is that care should start with healthier eating, more physical activity and support for changing daily habits, with families involved. For children younger than 10, the WHO does not recommend weight-loss medicines, bariatric surgery (an operation on the digestive system to cause weight loss) or weight-loss devices. It cites doubts about their safety and long-term effects. The agency says about 170 million young people ages 5 to 19 were living with obesity in 2024, a share that has quadrupled since 1990, from 2% to 8%. [3] [5] [10] [11] [12]

For adolescents ages 10 to 19, approved medicines such as GLP-1 drugs may be considered, but only after a supervised lifestyle program has not worked. Surgery could be an option under strict conditions for mature teens with severe obesity after six months of unsuccessful treatment. Luz María De Regil, who directs the WHO's nutrition and food safety department, said the evidence on GLP-1s in young people is currently insufficient. She said the agency may revise its advice as trial results come in. The guidelines also call for treating anxiety, depression, stigma and bullying alongside weight. They urge governments to make healthy food and exercise more affordable and accessible. [5] [9] [10] [11] [12]

The guidance arrives as drugmakers test these medicines in younger children. Forbes reports that Novo Nordisk said last month its drug Wegovy helped two of five obese children ages 6 to 12 drop out of the obese category after a year. Eli Lilly, AstraZeneca and Pfizer are also studying the drugs in children. The WHO's advice is not binding in the U.S. There, the American Academy of Pediatrics recommends offering medication to obese teens 12 and older alongside lifestyle treatment. Canadian pediatric endocrinologist Dr. Marina Ybarra welcomed the WHO's acknowledgment of medication. She said she hopes it helps win public funding for young patients in Canada. [2] [9] [11]

Key questions

Do U.S. doctors have to follow the WHO's child obesity guidelines?

No. The guidance is advisory and does not change FDA approvals or insurance rules. U.S. pediatricians generally follow the American Academy of Pediatrics, which recommends offering weight-loss medication to teens 12 and older with obesity. [11]

Can teenagers take GLP-1 weight-loss drugs under the WHO guidance?

Yes, in some cases. The WHO says approved medicines may be considered for ages 10 to 19, but only after a supervised diet, exercise and behavior program has failed. Long-term follow-up is needed. [5] [9] [10] [12]

Why does the WHO advise against obesity drugs for children under 10?

The WHO says there is not enough evidence on how the drugs affect children's long-term growth, development and mental health. It also points to a risk of misuse. It says the evidence will be reviewed as more trial data emerge. [2] [3] [5] [11]
