What is BMI?

Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple measure to evaluate whether you have a healthy body weight for your height.

How BMI is Calculated

The formula for BMI is:

BMI = Weight (kg) ÷ Height² (m²)
BMI Categories

18.5 – 24.9 Normal weight Lower risk for health problems
25 – 29.9 Overweight Increased risk for health problems
30 and above Obese High risk for health problems
Why BMI Matters

Having a BMI in the overweight or obese range increases your risk for:

  • Heart disease and stroke
  • Type 2 diabetes
  • Certain types of cancer
  • Sleep apnea and breathing problems
  • Osteoarthritis
  • Mental health issues like depression
Note: While BMI is useful for most adults, it has limitations. It may overestimate body fat in athletes and underestimate body fat in older adults or those who have lost muscle mass. Always consult a healthcare professional for a comprehensive health assessment.
