NICE no longer specifies target cholesterol levels for people with diabetes. Your doctors will use a calculator, called QRISK2, to work out your risk of heart disease using a number of factors such as age, BMI, gender, blood pressure levels, cholesterol levels and which type of diabetes you have.

If you want a general guide of how healthy your cholesterol levels are, find out your total cholesterol-to-HDL ratio

To find this, take your total cholesterol figure and divide it by your HDL figure. A result of less than four is healthy
