Obesity in Children: Warning Signs Parents Should Not Ignore

Childhood obesity has become a major concern worldwide.

According to UNICEF (2025), about 1 in 10 children and teens, roughly 188 million kids, are now obese. This means millions of children are affected. 

The main reasons are linked to daily habits like eating junk food, playing less outside, and spending too much time on screens. Childhood obesity is no longer just a city problem; it’s now seen in small towns and rural areas too.

When excess weight starts early in life and is ignored, it can lead to health problems such as diabetes, heart problems, and fatty liver disease at a young age. Obesity in children isn’t just about weight — it affects their health, mind, and future.

What Is Childhood Obesity?

Childhood obesity is a condition where a child gains more weight than is healthy for their age and height. It is usually measured with BMI.

BMI stands for the Body Mass Index. It is a simple measure that compares a child’s weight with their height and age. For children aged 2 and older, obesity is usually diagnosed when their BMI is at or above the 95th percentile for their age and sex.

Causes and Risk Factors of Obesity in Children

Kids can become overweight for a bunch of reasons, and often it’s a mix of several things:

• Genes and hormones: Some kids naturally gain weight more easily because of their genes or hormones that affect how their body uses energy.
• What’s on the plate: If healthy foods like fruits and veggies aren’t easy to get, kids might eat more fast food, snacks, or sugary drinks.
• Stress: Feeling stressed at home or school can make kids reach for comfort foods, which are usually not very healthy.
• Sleep: Not getting enough sleep can make kids hungrier and less active, which can lead to weight gain.
• Money and surroundings: Family income, where a family lives, and the support around them can affect the food kids eat and how much they move.
• Eating and activity habits: Eating big portions, snacking a lot, and not being active enough can all add up over time.
