Another factor that’s taken into account when considering surgery is a patient’s weight. Usually, doctors look at a calculation called the Body Mass Index, or BMI, that takes both height and weight into account. The range of BMI values for people whose weight is considered average is 18.5-25. If a person’s BMI is lower than this, they’re underweight; if it’s higher, they’re overweight. If the BMI is over 30, they’re considered obese.
Roswell Park patients having this procedure have ranged from underweight to obese. Altogether, 83% were either overweight or obese.
