Diabetes & Body Mass Index (BMI)


Find Diabetes Clinics »

Your body mass index (BMI) illustrates your body weight based on your height. It is used by medical professionals to estimate a healthy weight for your height so that they can diagnose cases of obesity and advise you if you are under or over weight. To find your BMI you must first measure your mass (weight) in kilograms and your height in meters. You then need to find the square of your height by multiplying your height by itself (using a calculator). Your BMI is then calculated by dividing your mass by the square of your height. A normal BMI lies between approximately 18-25 so that if your BMI is under 18 then you are thought to be underweight and if your BMI is over 25 then you are thought to be underweight. However, if your calculated BMI is above 30 then you will be classed as obese and you should discuss your weight with your GP so that you can come up with a management plan to help you lose weight as obesity will increase your susceptibility to numerous diseases included joint problems, diabetes and heart problems. This will ultimately reduce your life expectancy.
