If your BMI is higher than the healthy range (anything above 25, or anything above 23 if you have a south Asian background), you may be referred to a weight-management service that could help you to achieve a healthy weight, as well as looking at your diet and activity levels.
You can use the BMI healthy weight calculator to keep track of your BMI as your weight changes and to get advice on the best ways to achieve a healthy weight.
