Childhood overweight and obesity increase the risk of chronic diseases, including Type 2 diabetes, high blood pressure, fatty liver disease, heart disease, and sleep apnea if left untreated.
Early recognition and regular growth monitoring help identify children at risk, allowing timely intervention and reducing obesity-related complications.
Prevent childhood obesity by encouraging a balanced diet, reducing sugary drinks, processed foods, and fast food, while increasing fruits and vegetables at every meal.
Promote at least 60 minutes of physical activity daily and limit recreational screen time to support healthy weight management and overall child development.
Parents play a vital role by modeling healthy eating habits, active lifestyles, and positive family routines that encourage lifelong healthy behaviors.
Consult a pediatrician if your child is overweight or gaining weight rapidly for personalized assessment, treatment, and long-term prevention of obesity-related non-communicable diseases (NCDs).

Overweight and Obesity in Children and Adolescents

Early Awareness, Better Prevention, Healthier Future

Risk Factors for Childhood Obesity

Regularly eating foods high in sugar, fat, and salt, or consuming fast food.
Frequently drinking sugary beverages such as sweetened tea, soft drinks, and bubble tea.
Spending excessive time on screens (mobile phones, tablets, video games).
Lack of physical activity or regular exercise.
Staying up late or not getting enough sleep.
Having a family history of obesity (parents with obesity).
Emotional stress or using food as a way to cope with emotions.

Possible Health Complications

Physical Health Effects

High blood pressure
High blood cholesterol
Type 2 diabetes
Fatty liver disease
Snoring or obstructive sleep apnea
Knee pain, joint pain, and flat feet
Early onset of puberty

Emotional and Social Effects

Low self-esteem
Being teased or bullied

Children with obesity are more likely to become adults with obesity, increasing their risk of developing non-communicable diseases (NCDs) later in life, such as heart disease, diabetes, and stroke.

Preventing Childhood Obesity Starts at Home

Eat a balanced diet with all five food groups and include fruits and vegetables at every meal.
Limit sweets, sugary drinks, and processed foods.
Choose plain water instead of sugary beverages.
Enjoy family meals together and reduce screen time during meals.
Encourage at least 60 minutes of physical activity every day.
Limit recreational screen time to no more than 2 hours per day (excluding school-related activities).
Ensure children get enough sleep appropriate for their age.

Parents are powerful role models—children learn by watching what you do.

What Should You Do If Your Child Is Becoming Overweight?

Avoid blaming or making your child feel guilty about their body size.
Set healthy lifestyle goals and make changes together as a family.
Monitor your child's weight and growth regularly.
If your child gains weight rapidly, has underlying health conditions, or shows signs of obesity-related complications, consult a pediatrician.

Key Takeaway

Preventing obesity from childhood is a long-term investment in your child's health. Healthy children today are more likely to become healthy, strong adults in the future.
