Orlos is recommended for those with a body mass index (BMI) of 28 or more with other weight-related conditions, such as high blood pressure or type 2 diabetes.
If you have no underlying health conditions related to your weight, Orlos should only be used if you have a BMI of 30 or more.
BMI is a measurement that uses your height and weight to work out if you're currently a healthy weight. For most adults, the ideal BMI ranges from 18.5 to 24.9.
Whilst it's a fairly accurate measurement for most of us, do bear in mind that very muscular people like athletes, weight trainers or heavyweight boxers may receive an inaccurate 'overweight' or 'obese' reading. This is because muscle is much denser than fat.
To calculate your BMI, you need to divide your weight in kilograms by your height in metres squared - or just use our handy calculator and we'll do it for you!
