Calculate Your Adult Body Mass Index (BMI)

This service allows you to:

• Determine the BMI for individuals aged 18 and older
• Receive guidance on subsequent steps based on your BMI

Who Is Advised Against Using This Calculator

Avoid using this calculator for individuals who:

• Are below 18 years of age
• Are expecting
• Have been diagnosed with or suspect they might have an eating disorder
• Have a health condition that influences their height
• Preparation for Use

To use this calculator effectively, you'll need your:

• Date of Birth (to check your over 18)
• Height
• Weight

Interpreting Your Results

Your BMI will be indicated as a numeric value falling into one of the following categories:

• Underweight
• Healthy weight
• Overweight
• Obese

Understanding Your BMI Outcome

A higher BMI is linked to an increased likelihood of chronic health issues, including type 2 diabetes and heart disease. However, BMI alone is not a comprehensive health indicator, as it does not differentiate between muscle mass and fat.

For instance, a muscular build might result in an overweight or obese classification despite minimal body fat. This highlights why waist measurement can often provide a fuller picture of your health status.
