There's more to staying healthy than being a certain weight, size or body shape.

There are some simple tools available to assess your current body weight and wether it is putting you at high risk of illnesses such as type 2 diabetes, heart disease and some form of cancers.

The Body Mass Index (BMI) calculator is a guide to what is considered a healthy weight for your height.  It is quick and easy to use, and will provide you with a guide to whether you are underweight, at a healthy bodyweight or overweight.  The results will provide you with an indication of your health status to help point you in the right direction.

In conjunction with the BMI you can also check your waist measurement to help you assess your weight-related health risk.

These calculators are a guide only. Please seek professional medical advice about your own individual circumstances.
