📘 What Is BMI (Body Mass Index)?

Body Mass Index (BMI) is a numerical value calculated from a person’s height and weight. It is widely used as a screening tool to categorize individuals into weight ranges that may indicate potential health risks.

The BMI formula is:

BMI = weight (kg) ÷ height² (m²)

BMI is commonly used by:

• Health professionals

• Fitness experts

• Researchers

• Public health organizations

Although BMI does not directly measure body fat, it provides a useful estimate for most adults.

These categories help identify potential health concerns related to body weight.

🩺 Why BMI Matters

BMI is often used as an initial indicator because:

• It is simple and quick to calculate

• It helps identify weight-related health risks

• It is useful for large population studies

• It provides a general health screening

A high or low BMI may be associated with increased risk of:

• Heart disease

• Diabetes

• High blood pressure

• Joint problems

However, BMI should never be used alone to diagnose health conditions.

⚠️ Limitations of BMI (Very Important)

BMI has several limitations, and it may not be accurate for everyone:

• It does not measure body fat directly

• Athletes may have high BMI due to muscle mass

• Older adults may have normal BMI but high body fat

• It does not consider body composition or fat distribution

• It is not suitable for children without age-specific charts

For this reason, BMI results should always be interpreted carefully.
