A higher BMI increases the chance of developing long-term conditions, such as type 2 diabetes and heart disease. The BMI calculation is just one measure of health.

You can use this tool to:

• Check your BMI (for adults aged 18 and over)
• Get information about what to do next

You should not use this tool to diagnose any symptoms. If you are worried about your weight, contact your local pharmacist or GP surgery.

You should not use this tool if:

• You are under 18 years old
• You are pregnant
• You have been diagnosed with an eating disorder, or think you may have one
• You have a condition that affects your height
  
  

What you will need:

To use the calculator, you will need to know your:

• Height
• Weight
  
  

Ethnic background

The calculator will also ask for information on your ethnic background. This is because people from an Asian, Black African, African-Caribbean, or Middle Eastern ethnic background have a higher chance of developing health problems at a lower BMI.

When you enter information on your ethnic background, the calculator will give you more accurate advice about your BMI result.
