Body mass index (BMI)
Your BMI is calculated by dividing your weight in kilograms by your height in metres.
Work out your BMI using the safefood BMI healthy weight calculator.
People with a BMI of 30 or more have a high risk of obesity.
Your GP will measure your waist to see where you carry your weight.
The amount of weight you carry around your tummy can affect your:
- immune system
- risk of heart disease and diabetes
If you have more fat in your belly area than elsewhere, this may increase your risk of obesity.
For men, you have a higher risk of health problems if your waist circumference is more than 102 centimetres (40 inches).
For women, you have a higher risk of health problems if your waist circumference is more than 88 centimetres (35 inches).
Waist size cut offs are lower for people of certain ethnicities because of a higher risk of type 2 diabetes and heart disease.

Health problems linked to weight
Your GP will check if you have any health conditions linked to your weight.
These conditions include:

- raised liver enzymes
- pre-diabetes or type 2 diabetes
- heart disease

- physical limitations, such as shortness of breath and poor mobility

They may also carry out health checks to find out if your weight puts you at risk of developing health problems. These checks could include blood tests and measuring your blood pressure.
This will help your GP to understand your risk of obesity. They will help you decide on the best treatment plan.
