SIMPLE TOOLS TO HELP YOU AND YOUR DOCTOR ASSESS YOUR WEIGHT

These two easy-to-use tools will help you and your doctor to assess your weight. Just fill in the details and the calculations will be done for you.
  • What is your BMI?

    BMI or Body Mass Index is a tool that helps your doctor work out your weight category and your level of health risk due to your weight. BMI is calculated from your height and weight. While BMI isn’t always the perfect measure of weight category, it is a good start. Calculate your BMI and discuss the result with your doctor.

  • Calculate
  • Your BMI is: 
  • BMI value Weight category Health risk
    20-25 Healthy Weight Low
    25-30 Overweight Moderate
    Over 30 Obese High
  • What is your waist circumference?

    Measuring your waist circumference is another way to access health risks related to your weight. Generally, if your waist measurement is over 94 cm for a man or over 80 cm for a woman, your health is more likely to be at risk. These guideline figures can vary though depending on your ethnic background. Once you have measured your waist and filled in your details you can check your results against the chart.

    How to measure your waist circumference
    1. Measure directly against your skin
    2. Breathe out normally
    3. Ensure the tape is snug, without compressing the skin
    4. Measure halfway between the lowest rib and the top of the hipbone, roughly in line with the belly button.
  • Assess
  • Waist circumference and disease risk

    These are the waist circumference thresholds that indicate and increased risk of disease:

    If you are a woman:
    • your risk is increased at 80 cm or more
    • your risk is greatly increased at 88 cm or more
    If you are a man:
    • your risk is increased at 94 cm or more
    • your risk is greatly increased at 102 cm or more

    Limitations of waist circumference

    Waist circumference is less accurate in some situations, including pregnancy; where the person has a medical condition involving enlargement of the abdomen; for certain ethnic groups; and for children and young people.
