Understanding Body Mass Index (BMI)
Body Mass Index (BMI) is a widely used screening tool that helps assess whether an individual's weight falls within a healthy range relative to their height. While BMI is not a diagnostic measure, it serves as a valuable initial indicator of potential health risks associated with weight status.
How is BMI Calculated?
BMI is calculated by dividing a person's weight in kilograms by their height in meters squared (kg/m²).
BMI = Weight (kg) ÷ Height² (m²) BMI Categories and Health Implications

- Bone density loss
- Irregular menstrual cycles
- Fertility issues
Normal Weight (BMI 18.5-24.9)
- Better energy levels
- Reduced risk of chronic diseases
- Improved mobility
- Better sleep quality

Frequently Asked Questions
Is BMI accurate for everyone?
BMI is a general screening tool but may not be accurate for athletes, elderly individuals, or people with high muscle mass. It's best used alongside other health assessments.
How often should I check my BMI?
Regular BMI monitoring, typically every 6-12 months, can help track weight changes. However, sudden weight changes should be discussed with a healthcare provider.
Can BMI predict health problems?
While BMI can indicate potential health risks, it's not a diagnostic tool. Other factors like diet, physical activity, and family history also play crucial roles in health outcomes.
