What is BMI?

Body Mass Index (BMI) is a widely used screening tool that estimates whether a person has a healthy weight for their height. By calculating your BMI, you can determine if you are in the category of underweight, normal weight, overweight, or obese.

It’s important to remember that BMI is a general indicator and not a direct diagnosis of body fatness or health. However, it is a useful starting point to identify if further action or consultation with a healthcare provider might be needed.
