What to know
One number cannot tell the whole story
BMI does not distinguish muscle from fat or show fat distribution. It needs a different interpretation for athletes, pregnant people and children. This calculator is for adults.
When planning plastic surgery, the surgeon assesses health, medical history, examination findings and tests — BMI is only one part of that assessment.
