A Landmark Shift in Global Health
On October 7, 2026, the World Health Organization (WHO) released its first global guidelines for the treatment of obesity in children and adolescents, responding to a dramatic rise in prevalence. Since 1990, the rate of obesity in those aged 5-19 has
quadrupled, now affecting an estimated 170 million young people worldwide. These guidelines are groundbreaking not just for their clinical recommendations, but for their foundational principle: treating obesity as a chronic disease and demanding a 'person-centred' approach that moves beyond simplistic advice and tackles deep-seated stigma. The document stresses that care should aim to improve overall health and well-being, not just focus on weight loss.
Putting an End to Weight Stigma
For too long, children living with obesity have faced blame, bullying, and discrimination, not only from peers but sometimes within the healthcare system itself. The new WHO guidelines explicitly reject this, recognizing that weight stigma is a serious barrier to effective care. It can lead to anxiety, depression, low self-esteem, and avoidance of physical activity and medical care. The WHO urges health workers to create supportive environments and use 'people-first' language, such as saying 'a child with obesity' rather than 'an obese child'. This simple change reframes the issue, focusing on the child as an individual, not a label. The goal is to provide compassionate, age-appropriate support that protects both physical and mental health.
A Crisis Hitting Home in India
These global guidelines are critically relevant for India. According to the World Obesity Atlas 2026, India ranks second in the world, behind only China, for the number of children with high Body Mass Index (BMI). An estimated 41 million Indian children and adolescents were living with overweight or obesity as of 2025. The rate of increase is among the fastest globally, with projections suggesting 56 million could be affected by 2040 if trends continue. Key drivers of this crisis in India include a decrease in physical activity, with 74% of adolescents not meeting recommended daily movement, and increasing access to ultra-processed foods and sugary drinks.
What the Guidelines Recommend
The foundation of the WHO's approach is not medication or surgery, but comprehensive, family-centred support. For all children, the guidelines strongly recommend structured interventions that combine dietary changes, increased physical activity, and behavioural support. For children under the age of 10, the WHO does not recommend weight-loss drugs or surgery. For adolescents over 10, pharmacotherapy may be considered, but only after a supervised lifestyle program has failed to achieve the desired results. Bariatric surgery is seen as a last resort for adolescents with severe obesity and under strict conditions. The emphasis is always on a holistic plan that is sustainable and tailored to the needs of the child and their family.
