Understanding BMI for Teenagers

📈 What is BMI?

Body Mass Index (BMI) is a screening tool that measures body fat based on height and weight. For teenagers, BMI is interpreted using age and sex-specific percentiles.

🎯 Teen-Specific Categories

Unlike adults, teen BMI uses percentiles: Underweight (<5th), Healthy (5th-85th), Overweight (85th-95th), and Obese (>95th percentile).

⚠️ BMI Limitations

BMI doesn't measure body fat directly and may not account for muscle mass, bone density, and overall body composition in growing teens.

👩‍⚕️ When to Consult a Doctor

If your BMI falls outside the healthy range, or if you have concerns about growth and development, consult with a healthcare provider.
