Body Mass Index

Patients with a body mass index BMI of >35 have twice the mortality of matched controls.

BMI- what is it? Body Mass Index (BMI) is one measure commonly used to define % of body fat. It is defined as Weight (kg)/ height (metre) x height (metre) If you are a big, muscular rugby player the BMI overestimates your fat ratio and if you are a tiny, fine boned person the BMI underestimates the fat ratio.

However general guides are that a BMI of <18.5=underweight, 18.5-24.9=healthy weight, 25-29.9=overweight, >30-34.9=obese

The Orbera balloon may be a useful device for weight loss in patients with a BMI of 29-35.
