The importance of knowing your Body Mass Index (BMI)

Your BMI is a measurement that is a ratio of your weight and height. It’s a good way to gauge whether your weight is in healthy proportion to your height. In fact, knowing your BMI can help you - and your GP - determine any health risks you may face if it’s outside of the healthy range.

Being overweight can lead to a range of chronic conditions including:

  • Type 2 Diabetes
  • High blood pressure
  • Heart or blood vessel problems
  • Cardiovascular disease
  • Musculoskeletal problems

Being underweight can result in other health issues like:

  • Risk of malnutrition
  • Osteoporosis
  • Anaemia

The BMI scale

18.5 to 24.9 = healthy
25 to 29.9 = overweight
30 and above = obese
18.4 and under = underweight

It’s a good measure of your health, but not perfect

While it may be a great guide to establishing the amount of body fat you carry, your BMI won’t take into consideration your age, sex, ethnicity, or even muscle mass. It’s also not appropriate in determining a healthy weight in the elderly, children, pregnant women or even athletes.
