What is BMI?

Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. It is a simple tool used to quickly categorize a person's weight as underweight, normal weight, overweight, or obese.

Important: BMI is a general indicator and does not account for factors like body composition (muscle vs. fat), age, or sex. It should not be used as a sole diagnostic tool but rather as a starting point for assessing weight status.

BMI Categories (WHO Standard):

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 – 24.9
  • Overweight: BMI 25 – 29.9
  • Obesity: BMI 30 or greater
