Body Mass Index

The Body Mass Index (BMI) or Quetelet Index (QI) provides a simple numeric measure of a person's 'thickness' or 'thinness', allowing health professionals to objectively discuss over- and underweight problems with their patients.

A BMI below 18.5 suggests underweight. A Body Mass Index of 18.5 to 25 usually indicates normal or 'optimal' weight, while a number above 25 may indicate overweight. A BMI above 30 suggests serious, even health threatening overweight (obesity).
