Are you living with obesity?
Body Mass Index (BMI) and obesity
There are different considerations when defining obesity—it is more complicated than just a number on a scale.6 Obesity is a chronic disease and while BMI can be used to categorize obesity, your doctor may consider additional factors.7 Some of these factors include the measurement of waist-to-height ratio and the effect that excess weight has on your health or quality of life whether that be medically, functionally, or psychologically.8 BMI is calculated by comparing your weight to your height and can be an initial indicator on whether you should speak with your doctor.
Enter your height and weight to calculate your BMI.
Use the chart below to see the BMI categories for those aged 20 and older and their definitions.6 It’s important to note that the BMI categories can differ depending on a person’s ethnicity.7 Remember, your BMI is just one indicator for obesity—it is always best to talk with your doctor about it.
