FAQ’s of Body Mass Index

What is the BMI formula?

The BMI formula is weight in kilograms divided by the square of height in meters. For adults, this gives an indication of body fat. However, BMI vs body fat varies as BMI doesn’t account for muscle mass.

Many plastic surgeons use the BMI scale to determine a patient’s eligibility for certain procedures. Ideal BMI varies by procedure and surgeon, but typically ranges between 35-39 for cosmetic procedures.

Yes, BMI for adults is calculated differently than BMI for children. BMI interpretation for children takes into account age and gender-specific percentiles.

A healthy BMI is generally considered to be between 18.5 and 24.9. This can vary by individual health, so always consult a healthcare professional for personal recommendations.

Every surgery carries some risk like infections. However, these risks are minimized when procedures are performed by qualified, experienced surgeons in accredited facilities.

While BMI provides a general estimate of body fat based on height and weight, body fat percentage is a more accurate measure as it distinguishes between fat mass and lean mass.
