Health alert: India sees rise in child obesity with 56 million at risk by 2040

New Delhi: India now ranks second worldwide in the number of overweight and obese children, according to the World Obesity Atlas, raising serious concerns about a growing childhood obesity crisis in India.

The report warns that if current trends continue, nearly 56 million children in India could be obese or overweight by 2040, highlighting the urgent need for public health intervention and lifestyle changes.

Rising childhood obesity in India

The data shows that around 41 million children aged 5 to 11 in India have a high Body Mass Index (BMI), while nearly 14 million are already classified as obese. Experts say childhood obesity is no longer limited to adults, with cases increasing rapidly among younger age groups.

Globally, more than 180 countries have recorded a rise in obesity since 2010, and there are now more obese children than underweight children, signalling a major shift in global health trends.

Key causes: Sedentary lifestyle and poor diet

Health experts attribute the surge in childhood obesity in India to a combination of sedentary lifestyles, increased screen time, and unhealthy eating habits.

Doctors note that children today are more physically inactive, spend longer hours on screens, and consume junk food high in sugar, salt and calories. Poor sleep patterns, stress, and genetic factors are also contributing to rising obesity levels.

Early health risks: Diabetes, heart disease and fatty liver

Medical experts warn that obesity-related health risks in children can begin early and continue into adulthood. Obese children are more likely to develop insulin resistance, increasing their risk of pre-diabetes and Type 2 diabetes.

They also face a higher likelihood of hypertension, early-onset cardiovascular diseases, and fatty liver disease, due to excess fat accumulation in the body.

High triglycerides can lead to serious complications

Doctors highlight that high triglyceride levels in children — a condition where excess fat circulates in the blood — are becoming increasingly common. This can significantly raise the risk of heart disease, diabetes, fatty liver, and in severe cases, acute pancreatitis, a potentially life-threatening condition.

Urban lifestyle and ultra-processed foods are driving the trend

Experts link the rise in childhood obesity to urbanisation, easy access to ultra-processed foods, and aggressive marketing of unhealthy food products targeted at children.

Prevention: Healthy diet, exercise and reduced screen time

Health specialists emphasise that early intervention is critical to tackling obesity in children. Recommended measures include reducing processed and sugary foods, avoiding trans fats, and encouraging whole, balanced diets.

Increasing physical activity, sports participation, better sleep routines, and limiting screen time are also key to preventing obesity and improving overall child health.

Urgent need to address India’s obesity epidemic

With millions of children already affected, experts warn that India could face a surge in chronic diseases such as diabetes and heart conditions if the trend is not addressed.

The findings reinforce the need for strong public health policies, parental awareness, and lifestyle changes to curb the growing childhood obesity epidemic in India.
