Are You At Risk?

BMI, or body mass index, is one way of measuring whether you’re a healthy weight for your height.

BMI calculator

The result gives an indication of whether you’re a healthy weight, and if not, how over- or underweight you are. Body mass index (BMI) isn’t perfect because there are other things that you need to take into account when it comes to weight, but it’s a useful guide.

Your BMI is a measure of your weight relative to your height. The following categories are used to identify possible weight problems in adults.

  • Underweight
  • Normal
  • Overweight
  • Obese I
  • Obese II
  • Morbidly Obese
  • <18.5
  • 18.5 – 25
  • 25 – 30
  • 30 – 35
  • 35 – 40
  • ≥40
