Quick Summary

The **Body Mass Index (BMI)** is a universal screening tool used to identify if an individual is at a healthy weight for their height. While it doesn't measure body fat directly, it is a highly useful indicator of health risks associated with obesity and malnutrition.

Understanding Your BMI Score

The results of our BMI calculator are based on the standard categories established by health experts. Knowing which category you fall into can help you and your healthcare provider determine if further diagnostic testing is needed.

Official BMI Categories (Adults)

BMI Range Weight Status Potential Health Risk
Below 18.5 Underweight Nutritional deficiency, weakened immunity
18.5 – 24.9 Healthy Weight Low risk for lifestyle-related diseases
25.0 – 29.9 Overweight Increased risk of heart disease & hypertension
30.0 and Above Obesity High risk of Type 2 diabetes, stroke, and more

Important Considerations

While BMI is a reliable indicator for most people, it does have limitations. It may not be accurate for:
• **Athletes:** Muscle is denser than fat, giving a high BMI despite low body fat.
• **Elderly:** May have less muscle mass and more body fat for a given BMI.
• **Pregnant Women:** BMI ranges are not applicable during pregnancy.

Why Track Your BMI?

Consistently monitoring your BMI allows you to notice trends in your weight management. Whether you are aiming for weight loss or muscle gain, this index provides a baseline to measure your progress against global health standards.
